In Their Words

My name is Mikke Pierson, and I am a patient of Dr. Grinberg. Why did I pick him as my doctor? Well, first of all, he came highly recommended by our friend Dr. Dave Jenkins, who we know extremely well as a longevity doctor. When I explained my diagnosis, he said, “You’ve got to meet Dr. Alex,” as we call him.

When my wife and I met Dr. Alex, after talking to a number of other doctors, we just knew. You know when you talk to someone and they speak your language and speak to you directly? He has a great manner. His knowledge of the subject is extensive, and we just felt very confident.

Why did we choose this path instead of the traditional US medical path for early-stage Alzheimer’s? Because I’d read about the science and the debate and controversy around Alzheimer’s and its treatment. Frankly, the current American system isn’t for me. I don’t even get it.

There’s really no answer. I know things may change in the future, but Dr. Alex brings the kind of medicine I’m looking for. He follows what I call the ReCODE protocol, or Dr. Bredesen’s protocol.

He’s extremely knowledgeable about all the modern techniques and procedures you can do. We just came back from a clinic in Mexico. We met Dr. Alex down there.

The clinic was great. The people are great. I did a lot of different procedures.

I’d be glad to talk about it anytime with anyone. We feel like our journey makes sense. We’re doing something proactive.

Because of Dr. Alex and others, I am now living my healthiest life, which is how you start to deal with Alzheimer’s. Dr. Alex is so responsive and there for us, and he is exactly the kind of cutting-edge doctor we’ve been looking for. In some ways, it sounds strange.

I’m excited for this journey because I know I have a great team, and that’s a great feeling. So thank you.

After going through some very intense seasons in my life — an athlete’s mindset since childhood, being a high performer in the corporate world, and then a significant cancer diagnosis — I came out the other side feeling healthy again, but with a quiet concern still sitting in the back of my mind. I wanted to strengthen my immune system as naturally as possible, and that’s what led me to Dr. Grinberg.

From the moment I met him, I knew I could trust him. He’s open, transparent, and clearly brilliant — a physician who is also a scientist, someone who understands both the psychiatric and biological sides of health and brings a truly holistic, innovative approach to care.

What I appreciated most is that he never just handed me solutions — he explained how they worked, which helped me understand my own biology and cut through the conflicting information that’s everywhere in this space. He always gave me the time I needed and even connected me with some of the best people in the world in their fields. He also struck a real balance: recommending innovative, cutting-edge options when they mattered, but also simpler, more natural, cost-effective solutions when those were just as effective.

I’m so grateful for his care and looking forward to continuing this partnership. Thank you, Dr. Grinberg. Erin

Health and integrative medicine information can be overwhelming, making it hard to know what is truly right for you. This confusion can sometimes lead to unnecessary treatments that don’t address the root cause.

Before seeing Dr. Grinberg, I had consulted several doctors without success. He started from the beginning, carefully reviewed my history and tests, and finally identified the underlying issue.

What stood out was his professionalism, clarity, and ability to listen. He views the body as an interconnected system, not isolated symptoms.

Dr. Grinberg combines experience with strong analytical thinking, allowing him to tailor care to the individual rather than using a one-size-fits-all approach.

I am very grateful for his thoughtful care and highly recommend him to anyone seeking a thorough, insightful doctor focused on root causes.

Working with Dr. Grinberg is valuable because of his extensive knowledge and experience. His expertise in the immune system and cellular activity is especially important when dealing with complex illness. Prior to Dr. Grinberg, I was being treated by other well meaning integrative doctors but results were limited due to more narrow approaches and lack of understanding of deep biological processes.

Despite battling several serious conditions, my quality of life has improved under Dr. Grinberg’s care and I have hope that my situation will continue to improve. His approach is personalized, cautious, thoughtful, generous, and he is genuinely invested in his patient’s care. My family and I are very grateful for his support and consider ourselves very fortunate to have him on our team.

I did a lot of research before I found Dr. Grinberg. He is everything I had hoped he would be as a regenerative medicine doctor — and more. Not only is he extremely knowledgeable about the latest advancements in regenerative medicine and peptide therapy, but he is also genuinely kind and compassionate. He takes a very systematic, thoughtful and cautious approach to my care.

I have been diagnosed with a life-threatening autoimmune condition that affected my kidneys, nerves and lungs, and I have been dealing with some of the lasting effects of both the disease and its treatment. From the start, it was obvious that Dr. Grinberg is well versed in working with complex cases like mine. He looks at the whole picture, considers all aspects of my health, and is careful and methodical in determining what may be appropriate for me.

I am only at the beginning of my journey with Dr. Grinberg, so I can’t yet speak to the long-term results. What I can say is that I have tremendous confidence in both his knowledge and his judgment, and I feel very fortunate to be working with someone of his caliber. I likely would not have pursued regenerative medicine if I had not found a doctor I trusted this much. Dr. Grinberg has the depth of knowledge, experience and character that I was looking for in someone to help guide me through a complex medical situation.

Working together with Dr. Grinberg has been a dynamic but wonderful experience with his ability to weave in the psychological, physical, spiritual & energetic vibrational - frequency approach to the practice of longevity in a very professional manner!

I would highly recommend his expertise in the field subject matter to dispel the confusion created by other third parties.

Dr. Grinberg is a rare breed to reckon with his ability to listen and interact with his patients in a simplistic, but compassionate and understanding manner.

Kudos to the man with a network that spans many countries and medical jurisdictions !

I have had the pleasure of collaborating with Dr. Grinberg for the past three years, exchanging patient referrals and discussing complex cases. Throughout that time, I have come to deeply value his knowledge, experience, and ability to think beyond conventional approaches.

At Holistic Bio Spa® in Puerto Vallarta, Mexico, we frequently care for patients who return to the United States. Dr. Grinberg is a trusted colleague to whom we confidently refer patients for continued care. His understanding of cellular and regenerative medicine, combined with his thoughtful, innovative approach, makes him an invaluable collaborator.

What I appreciate most is the insight he brings to challenging cases. Our discussions consistently generate fresh perspectives and practical ideas that help us better serve our patients.

I wholeheartedly recommend Dr. Grinberg to anyone interested in biohacking, healthy aging, and regenerative medicine. His depth of expertise and pioneering spirit have earned my professional respect and personal trust.

I work in the longevity field, which means seeing more protocols, panels and promises than most people ever will. That is exactly why I did not want a standard program or just any longevity doctor.

Dr. Alex Grinberg is well known, on a global scale for his expertise in molecular and biological medicine. Having the opportunity to work with him personally has been extremely special and rewarding on all fronts.

What stood out immediately about Dr. Grinberg was how thoroughly he studied my background, my prior labs and my related diagnostics before he designed anything. He treats information as something to be understood and used properly, not collected and skimmed. By the time we discussed a program, he knew my history better than I did.

The personalized program he built genuinely moved the needle. My most recent labs showed improvement across the board. His mastery of integration is at the highest level I have seen. Peptides, stem cells, supplements, lifestyle and the rest are not deployed as separate tools in his hands. He knows how they work together, in what order, and why, and he builds the combination around the person in front of him. I also value that he is easily accessible and consistently willing to work a difficult health situation until he finds a solution.

There is no hurry in his approach, and that's the point. It's designed to endure. He makes the fundamental changes first, then builds a custom program to meet our intended goals, shifting and adapting the elements along the way. I'ts an honor and privilege to be his patient.

I’ve been working with Dr. Alexander Grinberg for the past year on advanced longevity and health-optimization protocols, with one goal: to understand how we can optimize the body, improve biological function, and potentially slow aspects of biological aging.

The results I’ve seen personally have been remarkable. Based on the biological-age testing and biomarkers we’ve been tracking, some of my results are now measuring approximately 14–15 years younger than my chronological age.

What makes Dr. Grinberg different is his deep understanding of biology and his ability to approach advanced interventions thoughtfully and strategically. We don’t just try things—we test, look at biomarkers, evaluate the results, and determine what makes sense as the next step.

Over the past year, we’ve explored a number of advanced protocols, including different peptide protocols, extensive biomarker testing, plasma exchange, exosome therapies, and NK-cell-derived exosome protocols as part of our broader longevity strategy.

We also traveled to Zurich, where I underwent an advanced apheresis blood-cleansing procedure. Before the treatment, my testing showed elevated levels of mold-related markers and other environmental toxins. Afterward, my follow-up testing showed significant improvements, including dramatic reductions in several of those markers.

And we’re not stopping there. We continue to test, evaluate, and refine my protocols to stay at the forefront of my longevity journey.

I truly believe I could not have navigated this level of optimization without Dr. Alexander Grinberg. His knowledge of biology, peptides, biomarkers, and emerging longevity science is exceptional. Most importantly, when I’m considering advanced interventions, he is the person I trust to help me understand the science, evaluate the risks and benefits, and decide what is appropriate for me.

For anyone interested in taking a highly personalized and advanced approach to longevity and health optimization, my experience working with Dr. Grinberg has been extraordinary.

Even though I was eating healthy, drinking enough water, exercising, and meditating I was still experiencing extreme fatigue, brain fog, and lack of focus. Dr. Grinberg educated me on alternative therapies that conventional western medicine simply doesn’t offer. It’s been just a few weeks since I have received plasmapheresis, hyperbaric oxygen, MUSE cell, and peptide therapies and I am already seeing a difference. I have learned how important it is to consult with a doctor who is able to look at the big picture of my health and guide me to personalized solutions that actually heal the body. On a personal note, I just love Dr. Grinberg, not only is he brilliant and on the cutting edge of research, but he is also kind and genuinely cares about his patients getting the best results they can.

I had the good fortune to be referred to Dr. Alexander Grinberg by a trusted colleague when I was seeking alternative treatments for several health issues. Specifically, I needed someone with expertise in peptide therapy to address macular degeneration and memory issues.

Here is what I experienced in Dr. Grinberg's care. His approach is thorough, flexible, professional and remarkably personal. He was exhaustive as he collected my personal history, assessed tests and discussed my goals. He always takes time to explain the science behind his recommendations and then checks in with me often to monitor my reactions and results. He is readily available by text and uses zoom for more detailed conversations despite his demanding schedule of international presentations.

Dr. Grinberg made it clear from the start that this would be a long process. In the four months since I started peptide treatment, I 've experienced improvement in my eyesight and long-term memory. When I tell people in the regenerative medicine field that I'm working with Dr. Grinberg they inevitably respond, "He's a brilliant"

Como persona con problemas del corazón, artriti degenerativa, victima de guerra, bombardeos, persecusiòn, secuestros y extrema torturas estoy muy agradecida con Dios por haber puesto en mi camino al doctor Alexander Grinberg.

Dr Grinberg tiene la poderosa qualidad de ver al ser humano detras del diagnostico. Su nivel de profesionalismo, empatia, compaciòn y respeto hace que se tome el tiempo de conoser a sus pacientes y ver sus necesidades individuales.

A diferencia de otros doctores que tube en el pasado, Dr. Grinberg me ayudò a entender mi enfermedad y aprender a manejar mis simtomas. Él ambient me ayudo a entender como mi severo trauma afectaba mi salud en general.

Una de las cosas mas importante en la que me ha ayudado Dr. Grinberg es a no sentirme culpable de mi enfermedad y entender que con un buen tratamiento y un buen cuidado medico puedo sobrevivir y llevar una mejor vida.

Basado en mi experiencia personal, creo profundamente que tomarse el tiempo para diagnosticar a un paciente hace la diferencia entre un buen y un mal profesional de la salud.

Sin ninguna duda encontrar un doctor que conozca tus necesidades individuales y se tome el tiempo de conocer a su paciente antes de comenzar un plan de salud hace la diferencia entre la vida y la muerte de usus pacientes.

Por esta razón yo recomiendo a las personas con enfermedades psicòlogicas y fisiolgicas que no se cansen de buscar un buen medico. Un medico capaz de entener la relation entre mente y cuerpo junto con las necesidades individuales de sus pacientes.

I run a biologics company, so I'm around physicians who talk about "cutting edge" medicine all day. Dr. Grinberg is one of the very few I trust with my own health.

What makes him different is how he thinks. He’s not linear and he’s not one-dimensional. When a new therapy comes across his desk, he doesn’t just accept it or dismiss it. He studies it. He works to understand how it acts, what it pairs well with, and who it actually helps, so by the time it becomes part of someone’s care, he already knows where it fits and the impact it creates. He’s constantly challenging the status quo, not just to be different, but because he refuses to believe the standard playbook is the best we can do.

That mindset shows up in his solutions. Nothing is one-size-fits-all. He connects dots other doctors don't see, pairs therapies most wouldn't think to pair, and builds something specific to the person in front of him. He did that for me, and he explained every step of the reasoning along the way.

If you're someone like me who is tired of conflicting longevity advice and cookie-cutter protocols, this is the doctor who's out there finding the better option, not waiting for someone else to.

I have been under the care of Dr. Alexander Grinberg for nearly 35 years, and I can say without hesitation that he has been nothing short of a blessing in my life. In the most difficult moments of my illnesses, he was the one who guided me through, supported me, and quite literally saved me more times than I can count.

Dr. Grinberg approaches every situation with exceptional attention and depth. He never focuses on just one symptom — he looks at the whole picture, every aspect of my health, my history, and my circumstances. Only after carefully considering all of this does he recommend treatment or procedures. To me, this is the highest level of medical professionalism and the true calling of a physician: to heal people, not just treat conditions.

After decades of working with him, I can say confidently that his expertise, compassion, and dedication are extraordinary. He is the kind of doctor who makes a profound difference in his patients’ lives.

Five stars — without a doubt.

With respect,

If you have questions, please contact me. Thank you!

I have been a patient of Dr. Grinberg for many years, and I cannot recommend him highly enough. He is exceptionally knowledgeable, talented, and personable, and he consistently stays current with the latest developments in medicine and scientific research.

Most importantly, Dr. Grinberg helped me substantially improve a health condition that had previously been considered very difficult to treat. His expertise, persistence, and thoughtful approach made a meaningful difference in my health.

He is also active in the scientific community and regularly publishes articles and podcasts, which I believe further reflects his commitment to staying at the forefront of his field.

From our first conversation and consultation Alexander has taken his time to guide me through the various modalities that will hopefully put my health in a much stronger state.

I am and will be forever grateful for what he has done and continues to do for me.

It was a great pleasure to meet both Alexander and his wife, while I was undergoing treatment in Puerto Vallarta.

After many years of trying to navigate through the traditional healthcare system I realized that conventional medicine wasn’t changing my results. Dr. Grinberg approached my medical problems by asking questions about me and my past. He wanted to know what I wanted from his help and what I had already done to prepare for my healing journey. One of the first things that I learned was that regenerating the kidneys was possible and that I didn’t need to settle for doing dialysis for the rest of my life. The most important lesson was to never give up . Medical breakthroughs are happening everyday. The process of working with Dr Grinberg has been life changing. We started with a protocol of peptides to help with the base work and address my autoimmune disease and now has evolved into a more advanced protocol involving MUSE cells. I am feeling very hopeful about the future and looking forward to my journey of healing. Thank you Dr. Grinberg.

I’ve been a patient of Dr. Alex Grinberg since 2021, when I first came to him through a recommendation for his expertise in longevity. Since then, he has become my go-to doctor for practically any health concern.

Alex is knowledgeable, attentive, and caring. He always takes the time to listen, answer my questions, and explain his recommendations. His approach feels thorough, personalized, and never rushed. I especially appreciate that he considers both the mental and physical aspects of health.

Over the years, his recommendations have included medications, vitamins, and peptides tailored to my needs. Working with him has made me appreciate the value of understanding my individual health needs and having a doctor who knows my history.

With so much conflicting longevity advice, having a physician I trust makes a real difference.

Alex, thank you for your professionalism, care, and deep knowledge of longevity. I’m very grateful for your support over the years and wholeheartedly recommend Dr. Alex Grinberg.

Over more than five years under Dr. Grinberg’s care, I have developed a deep appreciation for his knowledge, clinical judgment, and commitment to individualized care. As a chiropractor with three decades of experience in clinical practice, I place considerable importance on careful assessment, objective information, and a clear rationale for clinical recommendations. These are qualities I have consistently appreciated in his approach to my health.

My experience has involved detailed laboratory testing, thoughtful discussions about treatment, and most importantly, ongoing monitoring of my response to supplements, peptides, and other interventions. Dr. Grinberg’s attention continues well beyond the initial recommendation. Through regular monthly follow-up, he asks specific questions about how I feel, how treatments are going, and whether changes are warranted. That continuity has allowed me to discuss my progress and concerns with a physician who knows my history and remains actively involved in my care.

During my time under his care, I have experienced tangible improvements in my overall wellness and sense of well-being, along with significant gains in exercise performance and strength during resistance training. Improved recovery after workouts has been especially noticeable. For someone who values staying active while maintaining a demanding professional schedule, these changes have made a substantial difference in daily life.

As a diplomate of the American Board of Anti-Aging and Regenerative Medicine, Dr. Grinberg brings depth of expertise to the care of patients focused on longevity, sustained health, and physical performance. His background in psychiatry and neurodegenerative conditions further informs that work, allowing him to consider physical health, mental well-being, and daily function together. His command of the field is apparent, and he takes the time to explain his reasoning, address questions, and tailor his recommendations to each patient’s health history and goals.

In a field where patients encounter conflicting advice and expansive promises, I value the care with which he approaches assessment and follow-up. My experience has reinforced how much it matters to have a physician who understands your goals, follows your response, and remains available as your needs evolve.

Dr. Grinberg is also a valued friend, and this endorsement reflects my personal experience as his patient over more than five years. I regard him as a leading physician in longevity and regenerative medicine, and I am grateful for the expertise, attention, and thoughtful guidance he has brought to my health.

I have been in pharmacy practice for more than forty-one years, and I had the opportunity to work with many physicians. Some are considered physicians, but some others are more than physicians.

Dr. Alexander Grinberg, in my book, is considered one of the most intelligent, articulate, thoughtful and visionary physicians and scientists.

His background in immunology, molecular science and medicine makes him an avant-garde practitioner, leading science and medicine to new frontiers.

I have no doubt in my mind that his expertise in regenerative medicine, focusing on longevity and integrative medicine, will be his legacy.
