About Us

Dr. Steven Arima

Born in Los Angeles, Dr. Arima was raised in the San Fernando Valley and has lived in Valencia since 1989. He earned his bachelor's of science degree in biology with a minor in chemistry from California State University at Northridge. He continued his education to receive a doctorate of dental surgery (DDS) and a bachelor's degree in dental science from University of California at San Francisco. After being selected for a residency program in advanced cosmetic and general practice dentistry, Dr. Arima became a certified resident at Loma Linda Veteran's Hospital.

In 1989, Dr. Arima married Rhonda and moved to the Santa Clarita Valley to open his cosmetic and family dental practice in the new and growing community. In April of 2007, after many years of practice in Saugus and Newhall, Dr. Arima finished his custom built, professionally decorated dream office. The practice is located in a brand new building on Tourney Road in Valencia, where Dr. Arima continues to provide excellent cosmetic and family dental care. After many years of building beautiful smiles in Santa Clarita Valley, Dr. Arima maintains the enthusiasm and motivation that prompted him to pursue a career in dentistry. He holds membership with the American Dental Association, California Dental Association, San Fernando Dental Society, Academy of General Dentistry, American Academy of Cosmetic Dentistry, and he is a fellow in the International Congress of Oral Implantologists.

Dr. Arima's three children are his pride and joy: Ryan, the oldest, Megan, the only girl, and Chasen, the baby of the family. When he isn't working, Dr. Arima enjoys golf, scuba diving, playing online games, and he is a nationally ranked second-degree black belt in Tae Kwon Do. His main pastime is having fun with the family and enjoying his kids' many sporting and club endeavors.
