After growing up in New Jersey, I have come to call many places home.  My journey started in Connecticut where I did my undergraduate studies, and continued onto Seoul, Korea where I spent the year as a Fulbright scholar.  I also spent time in the Washington DC area performing and publishing scientific research at the NIH. I then moved onto New York City where I obtained my dental degree.  I then spent 6 years in San Francisco and received my medical degree, and completed my residency training in oral and maxillofacial surgery.  My wife, two daughters, and I have been happy with our time in California and we are excited to continue to call Northern California our home.

During my residency in oral and maxillofacial surgery at UCSF, I was trained in all aspects of this wonderful field including orthognathic surgery, facial trauma reconstruction, TMJ surgery, facial cosmetic surgery, benign and malignant tumor surgeries, and variety of different facial reconstructive surgeries for conditions such as craniofacial anomalies .  I took a particular interest in orthognathic surgery as it relates to both dentofacial deformities and facial esthestics.  In fact, that was the focus of my research project.  I am very passionate about maxillofacial surgery and I am equally excited to have the opportunity to provide my best care to all my patients at Kaiser Permanente.  I joined the Kaiser Permanente hospital system because it allows me to put patient care first without any compromise.
