Cape Code Restorative Dentistry not only specializes in general dentistry, but we are also a holistic cosmetic practice, aimed at using the safest and bio-comptible dental materials in our procedures.  The new and innovative tools we use are much safer than previously common materials. Our patients have loved the upgrade and have taken well to the use of these materials & holistic procedures. We recognize the impact of toxic materials to not only our bodies, but also to our environment.  


Cape Code Dentist

Dr. Shemanyuk

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 is also affiliated with the American Dental Association, Massachusetts Dental Society, Academy of General Dentistry, International Academy of Oral Medicine and Toxicology, and is a fellow of the International Dental Implant Association.


Dr. Shemanyuk’s top priority is to stay connected with the most current trends which she does through continuing education classes throughout the year having completed 100 hours annually and to provide her patients with the most expert and individualized care that they deserve.  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. 

A Note from Dr. Olga

“Welcome! Besides dentistry, I enjoy spending time with family and friends, gardening, cooking, and traveling. As I explored Cape Cod for the first time, I fell in love with the area and its people. I am excited to serve this community, and especially look forward to meeting each of you personally.  I hope to continue a lasting relationship, providing you and your families with a lifetime of good oral health.”

Stephanie graduated from Upper Cape Cod Regional Tech School before moving on to pursue a career in dental hygiene. She obtained her Associate degree from  Cape Cod Community College’s Dental Hygiene Program.

Stephanie resides in Sandwich. She is also a Cape Cod native. She likes helping others feel good about themselves which is what has driven her to become a hygienist. She has two siblings, enjoys being at the beach, boat rides, and spending time with her family and friends. 



Marie moved from Northampton, MA to Cape Cod in the fall of 2016.  Having worked in a large insurance company for twenty years and then managing a large dental office for ten years, sitting at home proved just not to be enough for her.  After enjoying some time being retired, Marie decided she needed to get out more and meet some new people. Having joined our office and working as a part of our front desk administration team has allowed her to do just that and she truly enjoys helping patients.  Her favorite pastimes  include gardening, reading and baking and long walks on the beautiful beaches that surround us. 

She's a member of The Friday Club.
