Dr. Clemma Nash, MD went to medical school because she knew the lifesaving value of traditional medicine, but she quickly learned that if you have a chronic illness, it is a different story. She saw a pill for every symptom given by multiple physicians, each working from their own view of the problem but with no attention to the potential underlying causes of the symptoms.

Dr. Clemma Nash, MD always knew there was more to medicine than pills and procedures and now focuses on patients with chronic illnesses. She utilizes the functional medicine principle of searching out root causes of imbalance and shifting patients from unwell to well at a deeper and more lasting level. In addition to board certification in Family Medicine, she also is board certified in integrative medicine (ABOIM). She also has extensive additional training in functional medicine, mold illness, and Lyme disease. She is in an ongoing mentorship with Dr. Neil Nathan and Dr. Jill Christa focusing on environmentally acquired illness and has trained with Dr. Tom Moorcroft on the treatment of Lyme disease.

With the tools of traditional, functional, and integrative medicine, she has helped patients with chronic gastrointestinal symptoms, fatigue, thyroid disease, mold illness, autoimmune conditions, and now Lyme disease, and more. Her toolbox far exceeds the training she received as a medical doctor and her expertise both in traditional medicine as well as integrative and functional medicine allows her to see your individual health puzzle from an expert perspective and guide you with a comprehensive, personalized, precision medicine approach helping you open the doors to recovery, healing, and vitality.


In Our Patients Own Words

  • “A year into the COVID-19 had me at my heaviest weight ever. I was able to focus on better eating and lost some weight but then stagnated. A few months later I joined a Reset Program led by Dr. Clemma Nash and things really began to move again. Less joint pain, better focus, and I could actually taste the sweetness of natural foods like fruit. So thrilled about the results and the encouragement from Dr. Clemma Nash, MD along the way.”


  • “I was typically burning the candle at both ends and in the middle. I finally realised I needed to take care of myself. I did the program with Dr. Clemma Nash, MD. My fatigue immensely improved. During the program, I noticed I had more energy and since completing it I continue to have more energy. I find myself still following the guidelines and the energy levels are staying improved. I've re-energized myself and can continue working full time, working with my husband building fences, and taking care of others including myself.”


  • “Dr. Clemma Nash, MD is a smart, compassionate physician who really knows her stuff! She recently helped me with my blood sugars being mildly elevated, joint pain, and brain fog. Working with Dr. Clemma Nash, MD I got my blood sugars back to normal and ended up losing 20 pounds! I can think much more clearly and my joints are significantly improved. Dr. Clemma Nash, MD was able to help me feel good again which made me want to be more active. She is extremely helpful and encouraging and had excellent advice when I was struggling. She has been a true gift to my health!”


Born in Newton, Massachusetts, Dr. Clemma Nash attended rotations at Hudson Medical Center, the Roxbury Health Clinic, and primary care rotations through the Massachusetts Center for Natural Health. Her inspiration continued during work with Doctors Without Borders, an NGO that brings free medical health care to under-served communities in South Africa.

After returning to America, she spent ten years as a full-time emergency physician before becoming Medical Director of the Brookline Stomach Health Center. While there, she became overly aware of the limitations that “conventional” medicine posed. As a response to this, Dr. Clemma Nash began studying Ericksonian hypnotherapy and body-oriented psychotherapeutic methods, along with herbs and supplements that are known to improve stomach health.

The root cause of her philosophy for diagnosing and treating stomach illnesses lies in a comprehensive approach that combines both physical and mental-emotional treatment methods. In addition to utilizing these treatments effectively, she also strives to teach patients that their good stomach health is dependent on:

  • A well-functioning autonomic nervous system and a stomach supplemented with proper enzymes.
  • A healthy stomach that is pain-free, creating a balanced emotional state in the process.
  • A supportive network of relationships with friends, family, and medical practitioners.

She is proud to bring her decades of medical knowledge to his own clinic,  UltraVitalityMD. She is equally honored to be joined by such an exciting and experienced team as the one she has recruited to work alongside her.
