Dr. Jessica Saliba

My name is Dr. Jessica! Growing up, I always knew two things: I loved medicine and working with children. After my mom immigrated as a dentist from Syria, I was inspired to pursue a career in dentistry. Being the oldest of four, I opted to stay in my home state of New Jersey to double major in Biology and French Literature at Rutgers University.

A Northeasterner at heart, I always wanted my 20s to be lived out in its biggest cities. I attended Harvard School of Dental Medicine in Boston, and upon graduation, I completed my general practice residency at Bronx-Lebanon in the Bronx.

Jassica Saliba

I moved to Philadelphia soon after to work at a private pediatric dental practice and treat children. I also worked on adults with special needs, and treated many who had severe cavities in the operating room at a local hospital.

One year later, I returned to the city that feels like home, New York City, and embarked on a rigorous two-year pediatric dental residency at Mount Sinai Hospital in Manhattan. After multiple exams, both written and oral, I became a Board Certified Pediatric Dentist. When I am not spending time getting to know all the kiddos on my schedule, I love to travel around the world, experience the great outdoors, eat good food, and spend time with my loved ones!

Dr. Georgio H. Woo

Dr. Woo - the Gum and Implant Specialist

My name is Dr. Georgio H. Woo. I am a board eligible periodontist, and my goal is to provide you with optimal gum health and beautiful smiles in the manner of comfortable experiences and personalized periodontal treatments. Periodontics, a dental specialty exclusively focusing on gum disease, other tooth-supporting tissues, and dental implantology, was my natural choice since I love science, medicine, and dentistry.

I graduated from Cornell University with a bachelor's degree in biological sciences with a concentration in molecular and cell biology, continued my education at Johns Hopkins University, and received a master's degree. Upon graduation, I worked at a biotechnology company in Seoul, South Korea where I was part of the first Korean human genome sequencing project that became published in Nature. At that time, I decided to be a dentist, received Dental Degree from Case Western Reserve University School of Dental Medicine in Cleveland, OH, and finished my periodontics residency at Columbia University College of Dental Medicine in the city of New York.


During my residency, I did research on reconstruction of periodontal tissues on dental implants for the treatment of peri-implantitis and received a Master of Science degree in periodontics. I am also appointed to a part-time faculty teaching periodontics at Columbia University College of Dental Medicine. I enjoy spending time with my wife and 3-year-old son James and exploring lots of outdoor activities. New York has always been my home state since my college years, and I am glad to serve my communities and patients here.
