Joon-Yong Koh, DMD  General Dentist

Dr. Koh 8x10

Joon-Yong Koh, DMD is a general dentist skilled in various aspects of general dentistry including composite restorations, crown/bridge restorations, endodontics, partial/complete dentures, routine and surgical extractions as well as implant restorations and placement. Dr. Koh is a certified Invisalign® Provider and is also trained in laser dentistry and CEREC restoration.
I grew up in a close knit family, and I keep that feeling in my work, too. I’m a dentist for the whole family, and I really get to know my patients.” For Dr. Koh, dentistry is more than working on teeth. It is about taking time to listen to the patients’ needs and concerns so that he may deliver customized dental care. But more importantly, it is about building lasting relationships and helping patients achieve a lifetime of optimal oral health and healthy smiles.
Dr. Koh attended the University of Washington in Seattle, WA for his undergraduate studies and completed a Doctorate in Dental Medicine at University of Pittsburgh School of Dental Medicine in Pittsburgh, PA. Upon graduating from dental school, he completed a General Practice Residency at Montefiore Medical Center in Bronx, NY and later finished the Comprehensive Implant Program at Columbia University in New York City, NY.
Dr. Koh consistently takes continuing education courses and attends seminars to update his knowledge on the latest and most effective techniques in dentistry. He feels that dentistry is continually changing and these courses help him stay on top of the latest technology available in order to provide the highest level of care for his patients.
Dr. Koh is an active member of the American Dental Association and Academy of General Dentistry. He enjoys playing golf, listening to music, watching movies, cooking and spending time with family including his recently born baby girl. Dr. Koh is fluent in both English and Korean.
