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 was very pleased with my visit with Dr. Schneider. He listened to everything that I had to say and answered all my questions. And I felt like he was really interested in what I was saying and that he really cared and wanted to help me with whatever problems I was having with my health. I'm very pleased with Dr. Schneider being my doctor. and I would highly recommend him to my family members and friends also. Thank you.

Yes, Mark has been my doctor for nine years and been a very good doctor, one that listens to you, explains this things to you that you could understand and helps you. And he's the best one I ever had during my lifetime.

Dr. Schneider is the best. So thankful that he is my PCP. It's hard to fit so much into a limited 8000 digit limit on how my life was restored through the expertise of this man, and he would probably say something like "all I did was turn him over to rheumatology". Thank You Dr Schneider.

Dr. Schneider has been my physician for over 40 years. I respect him and he has provided not only courteous, educational, and medical advise. He cares about his patients.

Everything was done very well. I don't see anything that needs to be improved. And when you asked about an appointment, I gave a two. Actually, that should be a four. Making an appointment was very easy and I appreciate everything. Thank you.

It is still difficult to make follow-up appointment when six months out with this office. I'll have to call 1-2 months before the six months Dr. Schneider recommended that I come in again. I'll have to wait a long time on phone then to get appointment. Dr. Schneider is very competent and treats me well.
