Shay Markovitch, DDS

An Israeli-born dentist and married with three children, Dr. Markovitch started his training in cosmetic dentistry over 20 years ago in Israel. He continued his training in the United States at Eastman Dental Center in Rochester, NY, as well as in countless continuing education courses.

His belief is that informed patients are better prepared to make the right decision regarding their oral health and well-being. Therefore, he takes the time to thoroughly explain all the stages of the treatment to his patients, as well as what options are available in modern dentistry.

Dr. Shay Markovitch is a certified Invisalign® and Lumineers® provider. Utilizing his skills to create beautiful smiles for his patients is one of his priorities because he believes that a smile is a mirror to the soul. When not performing dentistry, Dr. Markovitch enjoys sports, specifically soccer and basketball; however, he usually prefers to spend his time with his wonderful wife and three children.

He came to the United States and continued his dental education, completing his Post-Graduate Clinical Residency at Columbia University, College of Dental Medicine, (as Chief Resident), in Manhattan, NY, and most recently completing his Graduate Fellowship Hospital Dentistry at Presbyterian Hospital in New York City.

With ethical patient care at the core of his values, and a goal of providing quality dental care to all of his patients, that will not only benefit them, but enhance their lives as well. It’s no surprise that his patients feel completely at ease and confident in him to provide them with the utmost comprehensive dental care. It is what drives him to do this job that he loves.

Sean Kearns, DDS

Dr. Kearns’ philosophy is that dentistry is as much an art as it is a science. It is important to design a smile that builds self-confidence and to architect a bite that properly functions.

Later Dr. Kearns brought his luck to Baltimore where he went on to see the Ravens win the super bowl and to complete his Doctor of Dental Surgery degree at the prestigious University of Maryland School of Dentistry. While in Maryland, he bettered the community with his charitable work at the Perryville dental clinic for underserved populations. In order to expand his knowledge and culture, Dr. Kearns studied in Ireland at Trinity College.

In 2013 Dr. Kearns came to Westchester and did his General Practice Residency at Westchester Medical Center. He excelled in Implantology and Cosmetic Dentistry. It is here where he met his fiancé Gaby. Having active memberships in the Alumni Association of New York Medical College, the NYSDA, the 9th District Dental Association and the ADA, he is committed to furthering his education and participation in the community.

“Dentistry has afforded me the opportunity to work with my hands and to meet new and interesting people everyday.” Dr. Kearns enjoys painting, scuba diving, rock climbing and cutting edge technology.
