  • Dr. Cheryl Poon

    Pediatric Dentist Tribeca & Upper East Side

    Dr. Cheryl is a Board Certified Pediatric Dentist. She was a touch-it-all child at the dentist and was completely fascinated with all the cool tools and gadgets. She had her eyes set on being a dentist at a young age. Her dreams came true when she was accepted into an accelerated program, which allowed her to become a dentist in 7 years instead of 8 years. Even with an accelerated curriculum, Dr. Cheryl graduated Summa Cum Laude from SUNY Geneseo with a Bachelor of Science degree in Biology and a minor in Chemistry. She then graduated Magna Cum Laude from SUNY Buffalo School of Dental Medicine and was top 10 in her class allowing her to be inducted into the prestigious Omicron Kappa Upsilon National Dental Honor Society.

    It was then in her General Practice Residency in Newark that she found her passion for treating children. Dr. Cheryl still fondly remembers treating a scared little girl where she was able to channel her long-lost creativity and make an appointment full of sleepy teeth, sugar bugs and princess castles. She continued on her journey to pursue her pediatric dental training at Bronx-Lebanon Hospital Center and served as chief resident in her second year. She is also a recipient of the American Board of Pediatric Dentistry Richard C. Pugh Achievement award for scoring in the top 3% of the written boards.

    In her spare time, Dr. Cheryl enjoys going to concerts, watching movies, baking and traveling the world one country at a time. She is also passionate about giving back and volunteering her time to provide dental care to underserved populations. For the past 5 years, she has become an essential part of an outreach group that travels to Guatemala annually to treat the population who otherwise has no access to dental care.

    Dr. Cheryl understands that every child is special and needs tender love and care tailored to their individual needs. She takes a conservative approach to dentistry and believes that prevention is the most important goal in dentistry. She strives to give every patient a fun and positive experience to pave the way for a lifetime of happy and healthy smiles!

Upon graduation, Dr. Oh moved to New York, continuing her training at a hospital-based general practice residency at St. Barnabas Hospital in the Bronx. Dr. Oh’s top priority remains in providing the highest quality dental care, treating every patient with her gentle touch in a thorough and efficient nature.

    Also Speaks: Korean

    Q: How do you want people to feel when they come to see you? A: Safe. I would never do anything to harm my patients and I would never recommend treatment that I wouldn’t do on myself.

    Q: If you could tell people one thing about dentistry or oral health, what would it be? A: Come to your 6 month dental wellness appointments. It is the best, easiest, and cheapest way to make sure your mouth stays healthy.
