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.

I want to recommend Dr. Schneider for everything. He is an excellent doctor and the receptionist sometimes when I call in, they don't understand what I'm saying. My doctor gave me his extension and if I ask for my doctor, I should be put on directly to him. He gave me his extension and the nurse's station too. But sometimes they say can I help you? I said no, I said I want to talk to my... my nurse that knows me and knows that I don't usually call in unless there is a good...question that I need to ask about something. So, please change your people up there in the receptionist cause

The only down side is the inability to make my next appointment while in the office.
February 26, 2021
Yes, I was very satisfied with the provider, Mark Schneider. The only problem is not being able to schedule my next appointment. He wants me to come back in 4 months, and I have to call back to schedule that appointment. That does not make sense. That's not convenient. Other than that, I'm happy. Thank you.

Everything was really well good except that I made an appointment to come in for my physical and that's not what they made the appointment for. So that was a little disappointing, but I made another appointment for my physical. That's all I have to say. Thank you. Bye.

Dr. Schneider has always been a great doctor for me. He is always knowledgeable not only about my past history but what he is looking at not only at lab results but my physical well being as of today. Anything that might seem off he discusses with me. Then asks if I have any concerns as well. I continue to feel better mentally about my health and what is needed every time I have a visit with him. Thank you, Dr. Schneider!
