Brief Intro

Mark A. DeNigris, DDS Following in his father’s footsteps “This practice was established by my father, Dr. Guy DeNigris, back in 1954 and was built on developing long-term relationships with patients the old-fashioned, caring way. Like my dad, I enjoy helping people achieve healthy smiles, and my patients appreciate what I do. I can’t think of anything else that I would rather do for a living.” DDS: Graduated Head of Class, Georgetown University School of Dentistry, 1980 BA: Catholic University, 1975 Licensure: State of New York Advanced training makes the difference “In order to continue to improve and stay current, dentists must constantly learn about new advances in care. I have always sought out the best continuing-education courses available, preferably those that allow hands-on training.” Advanced Training: Includes hundreds of continuing-education hours in all aspects of dentistry Active in professional organizations “Professional dental organizations keep me informed of new developments in dentistry — all of which benefits you as a patient. Plus, I’ve had the opportunity to present and share techniques and difficult cases with other dentists.” Member: American Dental Association, Academy of General Dentistry In his free time, Dr. DeNigris enjoys sailboat racing, golfing, fishing and shooting.
