About Our Practice

Led by Dr. Jeffrey C.G. Mark, MD, who holds five board-certifications, All Functional Health employs cutting-edge technology to help patients regain their vitality and improve their quality of life. All Functional Health is a leading practice specializing in highly customized regenerative medicine, functional medicine, metabolic medicine, healthy aging and functional gastroenterology services. With convenient locations in the Bay Area-San Ramon, Menlo Park and Turlock, California, as well as Chicago, Illinois, the state-of-the-art offices offer highly personalized, holistic care. We also provide Telehealth services to patients from all 50 states and internationally.

Through conservative, drug-free options and minimally invasive procedures, patients always have choices and receive comprehensive education to make informed decisions. Whether it’s an anti-aging treatment with platelet-rich plasma, bio-identical hormone replacement therapy, drug free options for chronic pain or sleep management, or stress reduction, we seek to resolve the root cause of your health issues rather than just treat your symptoms. At All Functional Health, we have an answer for your health needs.

Dr. Mark provides highly individualized care plans for a variety of health conditions, which address patients’ needs and preferences while ensuring desired clinical outcomes. His patient-centered, science-based approach often includes a combination of prescribed pharmaceuticals and nutraceuticals, natural drug-free therapies, peptides, bio-identical hormone replacement therapies, platelet rich plasma and biocelldlar treatments, energy medicine and minimally invasive procedures.

The warm and friendly staff helps patients feel comfortable and at ease despite dealing with potentially serious health concerns. They deliver exceptional customer service and make items such as appointment setting, asking questions, and payment options seamless and simple.

To meet all your health and wellness needs, schedule a consultation with Dr. Mark at All Functional Health.
