Sally discovered Functional Medicine in 2009 after reading Dr. Mark Hyman’s book: The Ultra Mind Solution. “Dr. Hyman described everything I was trying to do within the conventional model. The book came at a time when I was feeling so disenchanted with medicine and had thought about leaving medicine altogether. It gave me hope that we could change the way we practice. “

Olga Shemanyuk, DMD
Dr. Shemanyuk has been practicing general and family dentistry since 1996 at which time she graduated with her first DMD degree from State Medical University in Kiev, Ukraine. She went on to complete a specialty program in therapeutic dentistry that covered restorative dentistry and endodontics. After gaining experience in a state dental clinic she opened her first practice in Kiev. In 2013 she earned her second DMD degree from Tufts University School of Dental Medicine in Boston. Dr. Shemanyuk has been serving patients at private practices throughout New England and the Greater Boston area including the MIT Dental Clinic in Cambridge, MA.
She believes in biosafe and holistic dentistry methods and knows full well that she is not only caring for her patient’s oral health in their dental treatment, but also for their overall health as the oral cavity is not a separate part of the body. Our overall health is a direct result of our oral health, which many people tend not to know. For her, dentistry is more than just a profession – helping people has always been her guiding principle.
