Dr Schwartz has been very helpful with my condition...always is attentive when I visit him.

February 07, 2019

Dr. Schwartz is an excellent health care provider. He provides the utmost care and concern for me as a patient. I am deeply saddened that I will lose the ability to continue under his care as of June 30,2019 due to having BCBS insurance. This dispute has proven to be a great disservice to me as well as other patients with BCBS.

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
