Mark Schneider DO
Program Director
Dr. Schneider decided to pursue medicine because he wanted to make a difference in people's lives. "I wanted to blend my interest in science with taking care of people, and I had several role models that influenced me, including my father and uncle. Both my identical twin brother and cousin became physicians also."
Dr. Schneider enjoys the continuity and trust he develops with his patients over the years, especially in becoming the family physician for generations of the same family. He has served as a California delegate to American Osteopathic Association House of Delegates for more than 10 years.
Dr. Schneider enjoys baseball, sailing, and tennis, as well as spending time with his family.
