Dr. Ruben Sandu

Dr. Ruben grew up in a large extended family of cousins and uncles in Eastern Europe and he immigrated to the US at the age of four. As the eldest cousin, he naturally ended up taking care of all his aunt and uncles’ kids. As a young child during play, he was often found examining the mouths of the ducks, chickens, cats, and dogs his grandfather owned. It comes to no surprise that he had a natural inclination to choose to become a pediatric dentist.

Dr. Ruben obtained his DDS degree from University of the Pacific Arthur A. Dugoni School of Dentistry and then completed a General Practice Residency at Community Regional Medical Center in Fresno, which is affiliated with UCSF. Realizing his passion for treating children and special needs patients during that time, he then completed a fellowship in Special Needs at Helen Hayes Hospital in upstate New York, which is affiliated with Columbia University. Afterwards, he completed his specialty residency in pediatric dentistry at The Mount Sinai Hospital in New York City. He is board certified by the American Board of Pediatric Dentistry.

After residency, Dr. Ruben practiced in Texas part time before settling back in Orange County, where he and his wife are from. While not at the office, Dr. Ruben enjoys spending time with his wife and daughter as well as reading on his balcony.
