"My family has gone to Dr. Penn for many years. He's one of a kind! In a not so fun procedure, Dr. Penn's professional side seems to put you at ease with just the right amount of humor. Downside: 0 rating or the worst possible are the Schedulers. You are not able to make an appointment. They will call you. My procedure was to be scheduled in July. I called 3-4 times and always got the same story... they only get a schedule 1 month at a time. I was on the list and was told, DO NOT CALL BACK. July 12th Alexandra called me to schedule an Aug. appt. I asked what happened to July. She said July was full. Worst experience of my life trying to schedule a Drs appointment. And yes, I told Dr. Penn and his Team. He was not happy!"

"From the first contact, Lorrie at the registration desk the process was positive. All staff were knowledgeable, professional, kind and respectful. I would recommend your facility!"
"I have told several of my family members and friends, and how very pleased I am with your service I had a colon scope done. all the people were very professional, efficient friendly, and certainly made an unpleasant experience pleasant. the nurses , doctors,, anesthesiologist, are all courteous, and their first concern is your well-being . My previous doctor had retired and I was concerned about who I would have in his place . I am so glad that I got Dr. Penn. He explained the procedure before you go in and then he comes and talks to in recovery after you’re done. The anesthesia they use is awesome. You’re in a twilight sleep in what seems like seconds and you wake up after the procedure in recovery as quickly as you went to sleep in the operating room. And so much better than going to a regular hospital for that type of a procedure"
