Dr. Roger Lau, a native of the Bay Area, has emerged as a trailblazing oral surgeon committed to advancing the field. Graduating as valedictorian from San Leandro High School, he went on to achieve a B.S. in Biochemistry from UCLA, earning a place on the dean's honor list. He continued his educational journey at UCLA School of Dentistry, obtaining his DDS degree.

Dr. Lau's pursuit of excellence led him to New York City, where he completed dual oral and maxillofacial surgery internships at Montefiore Medical Center and Mount Sinai Hospital. This experience set the stage for his four-year residency at Allegheny Health Network, Pittsburgh, including a chief resident year. Under the tutelage of global experts, he mastered dental implants, sleep apnea surgery, and corrective jaw procedures.

A member of prestigious organizations like AAOMS and ACOMS, Dr. Lau's surgical prowess spans dental implants, facial trauma revision, and more. Beyond his professional achievements, he enjoys snowboarding and travel. Dr. Roger Lau's journey exemplifies a commitment to innovation, learning, and elevating oral surgery to new heights.

Dr. James Kim was born and raised in a suburb of Boston, Massachusetts.  After completing his studies in biology and psychology at Boston College, he received his dental education and training at New York University College of Dentistry, where he also acquired a certification in Public Health.  After completing his studies, he began his dental career back in his hometown, spending several years in private practice, as well as spending much needed time back at home with family.  Life had different plans for James,  and he soon found himself in San Francisco where he plans to reside long term.

Raised by a family that stressed importance in conservative values and friendly, well-mannered interactions with others, Dr. Kim has translated these teachings to his relationship with his patients.  Dr. Kim had long sought to work in a practice in the Peninsula that would allow him to practice doing what he believes is in the best interest for his patients.  

Being a family oriented person, Dr. James spends much of his free time enjoying life with Michelle and their sons, Evan and Noah.  Outdoor living has been a great benefit for James and Michelle since their move out west.  Their hobbies include walks in parks with their beloved dog, Bailey, enjoying the wide variety of culinary treats San Francisco and the Peninsula have to offer, and the occasional winery excursion when time and weather permits.
