My primary doctor referred me to Dr. Parrish for a routine colonoscopy. Dr. Parrish took his time assessing my medical history and answering all the questions I had. The day of the procedure I went to the surgical center and everyone from the front desk to the surgical room were amazing. They knew I was nervous and helped put me at ease. I appreciate how each one took the time to explain what they were doing and what to expect. Dr. Parrish also swung by beforehand to check in on me and see if I had any questions. The procedure was a breeze - I basically took a nap and woke up 30 minutes later. Dr. Parrish swung by again to review results (all good!) with me. Highly recommended - I wish he could be my primary care physician!

Dr Parrish is hands down friggin amazing! He walked me thru the procedure multiple times so that I could understand what was going to happen, went thru all the pros & cons and gave me a good tip or two on how I could get back to my normal style of life. 10s across the board!

Hi, I'm 42 and this was my first visit to a proctologist's office. Dr. Parish was professional and made a sincere effort to clarify any questions I had and to relate to my situation. The experience was positive and I'd have no pause in recommending him to a friend.
