Unfortunately, Dr. Ray was not the GI I should have been scheduled with. While she was kind enough to counsel me about some of my issues, she informed me that I needed a General GI. She was kind enough to suggest a couple of them at Willoughby Hills Family Center which is closer to my home.

All the people that took care of me were wonderful and very very kind!!!!!!!!!!!! I think Dr.Ray is a wonderful Doctor!!!!!!!!!!!!!!!!!

Dr. Monica Ray is excellent. Before her, I had doctors attending to my particular problem, but they hadn't identified or recognized the whole picture. Dr. Ray did. She's personable, gracious, answers questions, offers information, so that now I know the whole picture and where I am in my medical situation. For me, Dr. Ray and the swallowing clinic is where I should have been sent to from the beginning.

Dr. Monica Ray was very thorough in her care for me. She listened which led to a correct diagnosis. I am very great full and would highly recommend her. It was very refreshing to have her as my doctor. She was very knowledgeable and trated me for something that had been increasingly getting worse over a period of 10 years. Other doctors just repeated the same tests and told me that they could not help me. Dr. Monica Ray did not do that. I am very grateful and pleased with the care that she provided.

very long wait for an appointment. providers heavily booked

Reviewed on Sep 21, 2018

Dr. Ray was very thorough and seemed to genuinely care about this health issue. She carefully reviewed the medical records that had available. She asked specific questions. She did not waste my time by requesting that I repeat procedures that had previously been done. I felt respected, and valued. I felt that she truly LISTENED to my concerns. She provided a plan of action that gave me the hope and confidence in her ability to correctly identify the issue and provide the specific care that I need. I feel that I will finally be treated and healed of this issue that I have suffered from for several years. Her bedside manner was very careful. She gave me hope. I left the appointment extremely happy. I am looking forward to working together with her regarding this issue. I am of the opinion that ALL previous doctors have failed me regarding this health issue. They did not have the answers so instead of referring me out, or continuing to work with me, I felt abandoned. I sought out the Cleveland Clinic based on a program I viewed on TBN regarding this issue. I am happy that I followed through and called. Dr. Ray has been a very refreshing and I appreciate the care, concern, respect and options she provided. Excellent!!

Reviewed on Sep 21, 2018

Their were several steps before seeing Dr. Ray. However, I understand that it only aided in her having as much information to review prior to seeing me. This saved her time as well as mine. Lastly, she did not just come in say a few things and dismiss me. She really took the time to review, evaluate, ask questions to suggest the best possible plan of action.

Dr Ray, is a very good doctor, she listens and she gets to the root of the problem. She's very kind!
