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.

This is the best doctors office I've visited. The doctor is great, he actually listens to you, when you have questions and takes the time to explain. The nurses and front office and schedulers were great, friendly and personable.

Dr Schneider has been our doctor for over 35 years He has always been attentive and taken the time to address our concerns. We appreciate him ver much

Dr Schneider is knowledgeable and caring, if a bit stern. He's been our doctor over 25 years now...??
August 15, 2019
I have told my family and friends how disappointed I am in our health care and cost. What use to be somewhat manageable in cost has more than tripled and the care is only 10% as to we used to get.

Dr. Schneider is an outstanding doctor and I have been his patient for over 25 years I drive well over 30 minutes to see him because that is how much I value him as my doctor. He is caring and spends a lot of time with me answering all of my questions and addressing all my health concerns. I would highly recommend him to anyone.

Our doctor has always been very personable and we wouldn't trade him. He has been our doctor for over 25 years and his service has always been great! Other doctors he has had to refer us to states that Dr Schneider keeps well detailed and informed notes about his patients which in turn keeps everyone informed and able to treat patients with the best care. He's the greatest. We appreciate his expertise!

Dr.Schneider is an amazing doctor. He is knowledgable, has a great manner and explains things. I did experience a problem with long wait times. I had booked an appointment and waited 2 hours and was told there was still 1 patient ahead of me. I had another appointment and had to reschedule. I understand that there are times that unexpected things come up, however; it would be nice to have a staff member inform the patient that their wait time will be longer than anticipated. Thank you.

If you're looking for a provider who will listen to your concerns, Dr. Schneider is the PCP for you. Great bedside manner, always takes time to answer all your questions and his residents are great. I've been a patient of his for 20 plus years and if I didn't feel like he cared about my health, I wouldn't have stuck with him this long.
April 22, 2019

As I mentioned Dr. Schneider is an excellent doctor. He has always looked out for my families best interest. He was caring and assisted with providing the care my husband needed for his health. He asked me if there was anything I need to help care for my husband. He was concern about me getting sufficient rest, while caring my husband. Dr. Schneider cares about his patients, there not just next patient.

Dr. Schenieder is one of the best providers I know. Personally he has been my primary doctor for 15 years. I am a Registered Nurse. I have been in nursing for 22 years. So I know a little thing or two about good doctors. And Dr. Schneider is exceptional. PIH is truly lucky to have him. However us, the patients, are not lucky to have PIH.
