His comments about me, the patient, knowing my body better than anyone when I made the suggestion allowed for me to recognize that he has my best interest at heart.

Dr. Lashner is an amazing doctor and has met every expectation I have had regarding my care and treatment at the Cleveland Clinic. When I first came to the Cleveland Clinic I saw Dr. Anthony Senagore. He helped get me on track and then he turned my care over to Dr. Lashner. I have been seeing Dr. Lashner since July 2000. I have not looked back or regretted that decision in any way during the last 21 years! He is the reason I am doing as well as I am. Chrohns is an evil disease, but he has helped make it more manageable.

The doctor invited me to message him using Mychart anytime and that was very reassuring to me.

My referring provider & I both sent my medical records to Cleveland Clinic as requested. Dr. Lashner had not looked at ANY of my records before my appointment. He said I didn't have any records there & I told him I brought everything that had been faxed. I showed him the envelope and records that Cleveland Clinic had mailed back to me. He said, "Maybe they're under scanned documents." He looked & they all were there. I would have liked for him to have had some knowledge of my problems before I was seen by him. I was very disappointed.
