Lorraine Kosztyu, DMD

I graduated from UMDNJ — New Jersey Dental School (now Rutgers) with honors in 1994 as an OKU Dental Honor Society member. Following dental school, a one year dental residency was completed at Monmouth Medical Center in Long Branch, NJ. My undergraduate studies for a degree in biology were at Douglass College, Rutgers University. Raised in Ewing, NJ, I attended Notre Dame High School. I have maintained a solo private family general dental practice in Lawrenceville, NJ since 1998.

Lorraine Kosztyu, DMD

As a proponent of organized dentistry, I belong to the ADA, NJDA (New Jersey Dental Association) and its local component, Mercer Dental Society. I am a Past President of the Mercer Dental Society serving twice as President. I currently sit on the Board of Trustees as a Trustee for Mercer Dental Society. I am also a member of the Peer Review Committee and many other committees at the state level.

My staff and I aim to deliver the highest level of detailed and comprehensive care for patients. This includes a focus on the health of the teeth, gums and the surrounding structures of the tongue, face, neck and throat. All aspects of dentistry are performed at my office, with referral to local dental specialists when required. I enjoy cosmetic dentistry and all aspects of implant dentistry. Parents and children are treated at the office making it a convenient office for family visits.
