Dr. McMorrow is the ONLY Dr I have ever seen who walks in having already read your chart, remembers your history and knows what is bringing you in so he can immediately start addressing your concerns. I hadn’t been in in almost tShow morewo years and he was still up to date with what we went over on my last visit and asked great follow up questions. And ON TIME! I did not feel like a number to him. Also, this may just be me, but I appreciate the old school use of pen and paper to take notes while making eye contact. He wasn’t sitting there staring at the screen and typing away. I’m sure he used a laptop after he walked out, but was sure nice to be looked and spoken to while questions being asked.

The instructions from the office leading up to the procedure were very clear and easy to follow. The day of the procedure, everything/everybody was extremely professional while at the same time being so helpful and kind.
