Dr. Vagan Tapaltsyan, DDS, PhD

A Berkeley resident since 2010, Dr. Tapaltsyan spent the first part of his childhood in Europe, attending a foreign language immersion preparatory school before moving to the US for high school. He went on to graduate Summa Cum Laude with a BS in Biology from the University of Central Oklahoma, where he was also a member of the sailing team. Continuing on his lifelong path of going West, Dr Tapaltsyan moved to California for graduate studies and received both his DDS and PhD in Stem Cell and Regenerative Medicine from UCSF, where he currently holds the rank of Assistant Professor and is the Director of Evidence-Based Dentistry Program and an instructor for the UCSF Dental Implantology Training Program.

In addition to practicing dentistry and teaching, Dr. Tapaltsyan's research interests include dental implantology and dental stem cells biology, which can one day help us regenerate new teeth and bone. He has authored many research articles and book chapters on this subject and lectures internationally.

Dr. Tapaltsyan is a member of the American Dental Association, California Dental Association, American Association of Endodontists, American Academy of Sports Dentistry, and American Academy of Laser Dentistry. In his spare time, he enjoys occasional crewing for sailboat races, drawing, hiking, reading, and exploring the great outdoors with his German shorthair pointer Duke.

Dr. George Ibrahim, DDS

Born and raised in the Bay Area, Dr Ibrahim spent his childhood in South San Francisco until graduating from South San Francisco High School and moving to Los Angeles to begin his undergraduate education at UCLA. He went on to graduate with honors and received a Bachelor of Science in Molecular, Cellular, and Developmental Biology. After completing his undergraduate studies, Dr Ibrahim moved back north and received his DDS degree from the University of the Pacific, Arthur A. Dugoni School of Dentistry in San Francisco, where he served both as class president and associated student body president. While at UOP, Dr Ibrahim researched comparative strengths of adhesive and restorative materials used in modern dentistry.

Dr. Ibrahim is an Assistant Professor at the UOP Dugoni School of Dentistry, and is a member of the American Dental Association and California Dental Association. Outside of dentistry, he spends his time reading, swimming, going on hikes with his dog Tiger, and playing chess poorly.
