Make an Appointment


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.

Dr. Schneider has always been an exceptional doctor. He has always listened and has always spent the time when I had an appointment, even if it's been over and beyond. Like I said, he's an exception doctor. He cares about his patients and I would recommend him to anybody.

Excellent service. They were very patient with us and understand what we needed. Thank you doctor and nurses for caring with us and communicating with us what we've been through with the little issues. Once again, thank you for your care and patience with us. Sincerely, (PHI removed).

I made a mistake on the very last question if I would refer Mark Schneider, Dr. Schneider, to friends and family. I meant to hit four like, yes, indeed, but I hit two by mistake. Maybe you can fix it for me. Thanks a lot. Other than that, he was a perfect doctor with a perfect visit and the perfect staff, and a perfect experience. Thanks for caring. Bye bye.
