Appointment was great! I waited only minutes to see the doctor and he was very thorough with learning my medical history and current issues. He seemed very knowledgeable and explained the next steps clearly. The employee helping schedule my next appointments was great too and I really appreciated the fact that they are scheduled and I don’t have to worry about making other calls myself later on. Overall I’m super impressed by everyone and can’t say enough good things!! Thank you!!

Dr. McMorrow and all the staff made the experience as pleasant as could be. My only negative feedback would be that the doctor gave his post-op findings while I was still coming out of the anesthesia so I don’t even remember him talking to me. I was still babbling about golf carts!

Dr. McMorrow and his team provided excellent care during my recent procedure. He is very easy to talk to while explaining the procedure and was easy to understand the results afterwards. His team reflected his care and concerns in a very supportive way. I highly recommend.

The staff here was so accommodating; from making the appointment to follow up on the day after my procedure. My wife had a colonoscopy the month before I did and we experienced the same treatment!

Extremely professional. He takes the time to explain everything in easy to understand terms. The nurses and support staff are all great as well. I could not recommend them more.

This is my first time to be seen by a physician at Gateway. I was astonished by the warm and caring attitudes of everyone there. The support staff is unbelievable both in person and on the phone. Dr. McMorrow helped me to stop feeling so frantic about current health issues. I'm grateful to have found this group of professionals!
