Mehran Abbassian, DDS

I graduated from University of the Pacific School of Dentistry in San Francisco in 1988. In 1989, I moved to the Santa Clarita Valley. I purchased my office in 1990 located in Newhall, California. In 2007, I moved to my state-of-the-art practice located on Tourney Road, Valencia. It is a full service dental office, for adults and children. Throughout the years, I have served on many boards for non-profit organizations. In early 2000, I was the assistant clinical professor at the University of the Pacific School of Dentistry. In 2011, I was the President of the San Fernando Valley Dental Society which is a component of the California Dental Association and the American Dental Association. In my free time I enjoy playing golf and of course my family and friends.
