This was the first office visit with this particular doctor at this practice. It was a good experience.

April 25, 2019

My appointment was at 9:20, but I didn't see the doctor until 11:10. His assistant showed up at around 10 and asked many details about my condition. That's good! The only complain is that the doctor kept me waiting for too long. I didn't prepare to wait for 2 hours in the exam room.

wonderful physician - clarified my questions and provided multiple viewpoints of my condition to consider

Dr. Mark Schwartz is a wonderful doctor. I would recommend him to family and friends suffering from IBS/IBD.

March 14, 2019

My doctor was very interested in my health and explained everything very clearly. He is definitely concerned in my wellness. I am so glad I have found him as my medical situation can leave me very, very concerned and Dr. Schwartz always is there to answer any questions I may have.

March 14, 2019

Messaged Dr. on 3/18 with concerns about a script. Never received a reply.

February 28, 2019

I have no issues with my care or doctor himself. The only reason I cannot choose 10/10 is because even though I can see my test results in my online portal, no one from the office has either called me about them and not have they followed up with the appointment scheduling with the secondary specialist my current doctor wanted requested ASAP.

February 07, 2019

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.

the staff and everyone else I talked to were very helpful and knowledgable.
