Our History

Growing up in the Soviet Union, Drs. Ronkin and Shwartzman heard about the advanced healthcare available in the United States. They wanted to learn to provide high quality care and practice in an environment where thy can always continue to learn and flourish. When they came to the U.S. they were accepted into the world-renowned Tufts Dental School, which is actually where they met each other. Sharing an identical dream, they found that they both had the same drive and ambition to pursue it.

Cosmetic Dentistry

In 1994 Drs. Ronkin and Shwartzman opened their first Dental Practice in Canton, MA. In 1995, they were the first office in New England to offer laser tooth whitening. That was the beginning of two things for Ronkin and Shwartzman: an unprecedented approach to dentistry later called “cosmetic dentistry” and earning their keep as the pioneers of modern dentistry.


In 1996, Drs. Ronkin and Shwartzman joined the American Academy of Cosmetic Dentistry. In the group of advanced dentists dedicated to the art and science of dentistry, Drs. Ronkin and Shwartzman found their place. They began eradicating sliver fillings from the practice, patients were coming in and asking for veneers and teeth whitening was becoming more and more popular.


Also in 1996, Ronkin and Shwartzman began attending cosmetic dentistry courses at the Las Vegas Institute for Advanced Dental Studies. Along with the other 1% of dentists in the country, the doctors learned techniques that kept them at the forefront of high-tech dentistry. They began changing peoples’ lives by giving them the self assurance they lacked from not being able to smile confidently.

In 2002, Drs. Ronkin and Shwartzman began shifting in a new direction. They continued to change people’s lives, but now they actually had the tools and skills to change their patients’ quality of life. Undergoing over 100 hours of continuing education on the concept of neuromuscular dentistry, the doctors began taking not only the teeth into account, but also incorporating the roles of the joints and muscles in relation to the teeth. This allowed them to help patients relieve TMJ symptoms such as headaches, neck and back pain, jaw pain, tingling of the fingers and many more. With the help of neuromuscular dentistry, Dr. Shwartzman has treated many patients with sleep apnea and has given them an alternative to the CPAP and a healthier sleep, resulting in more productivity and happiness.

It also allowed them to restore teeth in such a bite that actually increased the longevity of their restorations. The days of when crowns “needed to be redone” every 5 years were over. If done correctly, and if the patient follows all recommendations, restorations can actually last a whole lifetime.


The International Association of Physiological Aesthetics was founded in 2005 and Drs. Ronkin and Shwartzman were members since the foundation of this organization. Having already brought modern dentistry back to Russia, the doctors felt the importance of an international organization that brought the highest quality professionals together. Dentists who are passionate about improving the quality of life for their patients, were now able to resource the research being done in various countries across the world. Drs. Ronkin and Shwartzman are not only members, but they attend the annual IACA meeting every year and even bring a group of dentists from Russia. The goal is to bring the level of dentistry up wherever possible so that patients around the globe can have access to this amazing dental care that we know changes and prolongs lives.


This unique form of straightening teeth using invisible aligners was introduced to the market in 1999. That year Drs. Ronkin and Shwartzman were one of the first to get certified using this technology that will have gone on to revolutionize the orthodontic world. Eleven years later, Invisalign has grown into a multi-million dollar company with 1.3 million people have used their product. The highest level of achievement with Invisalign that a doctor can attain is the “Preferred Super Elite Provider”, Drs. Ronkin and Shwartzman are 2 of 13 in the whole world that hold this status. With over 800-lifetime cases completed and over 100 just in the past 6 months, the doctors have taken their orthodontic achievement to the highest level. With the help of Invisalign in combination with neuromuscular orthodontics, Dr. Ronkin has helped many patients beyond just straightening their teeth. For children, neuromuscular orthodontics lays down the foundation for healthy development and prevention of sleep apnea, respiratory disease, heart disease and other illnesses.
