Long dedicated to her passion of doing the right thing for people, she realized her talents in dentistry purely by accident, but was gratified to discover she held a natural skill in the discipline. In addition to receiving a Bachelor of Arts in biology and chemistry from the University of Denver in 2000, she earned a Doctor of Dental Surgery at the New York University College of Dentistry in 2004. After completing an internship and residency at Beth Israel Medical Center, Dr. Gohard was accepted in the exclusive dental postdoctoral fellowship program in implantology at NYU Langone Medical Center.

Dr. Gohard is board-certified in New York, New Jersey and Pennsylvania, and concentrates her practice in restorative and cosmetic dental procedures. She strives to educate and empower clients to take an active role in their care and ongoing periodontal health, rather than simply resolving the issues that brought them in, and is proud to have cultivated trust and a strong rapport with her patients. In recognition of her outstanding record of practice, Dr. Gohard has been named as an Outstanding Dental Provider, the 2020 Best Dentist in Florham Park and listed three times as one of America’s Top Dentists.

As a part of her commitment to community service, Dr. Gohard participates in the Give A Smile program, offering free or reduced-cost treatment for first responders. She attributes her success to her professional mentors and to the connections she has made throughout her career. She looks forward to continuing to refine her patient care and skills in the coming years.
