I have never had a bad experience with Dr Schwartz he always listens and takes his time to answer my wifes or my questions and never tries to hurry appointments. His staff is great and always is there to answer questions.

My care provider for my crohn's was Dr Jason Swoger who I was very pleased with. I respected his decisions concerning my medical condition & was sorry to see him go. He referred us to Dr Marc Schwartz who has also earned my respect & I also trust his decisions concerning my medical condition. He listens when I have concerns & comes up with the better treatment

Jennifer the lpn or rn Who checked me in was extremely kind and helpful. I was very upset when I arrived because the garage I parked in was very confusing and I had a difficult time finding my way to the hospital. Jennifer really help to me feel comfortable welcome and relaxed. The young girl with a long dark hair who checked me out was equally as sweet and kind.

Dr Schwartz Was patient yet very thorough and explained everything in plain language. He took time to listen to all of my concerns and was familiar with my health history before he came in the room.

Dr. Schwartz was excellent. This is the first time I have seen him but I am going to be a regular from now on.
