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. Mark Schneider has been my primary physician for over 31 years. I wouldn't trade him for any other doctor in the world. He is the best doctor.

Dr. Schneider is caring and a wonderful doctor. He listens to me and all my concerns. His intern was awesome as well. He listened to me and asked all the right questions.

The doctor's resident was extremely kind and helpful. Dr. Schneider himself was extremely rude and smug. I will never book another appointment with him.

I've been seeing Dr. Mark Schneider for almost 30 years, and I went to him because he is like the old-fashioned doctors that used to listen and address each one of your concerns. He takes his time with his patients, and when he sold his practice to PIH, I followed him. I won't see any other doctor than Dr. Schneider. He's great. So that's what I have to say.

I have been visiting Dr. Schneider for Uber 30 years, and it's been a blessing to have a great Dr. like him who takes the time to listen and give you proper feedback. However, since they have come on board with PIH. I've noticed that it's changed quite a bit. And not for the good, they're always short staff or so, I've been told in addition to that. Whenever you try to get through to someone, if you're running lateI, or have to get a live person on the phone it's ridiculous and your messages eacalls ectrerturnwsI

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.

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.
