Dr. Guerra is one of the kindest doctors I know. I have gone to him for the past 10-12 years. I dread the day he retires. I don't see him often, but when I do I feel like i am getting the best care possible.

I will definitely continue recommending Dr. Guerra to family, friends, and others. Dr. Guerra has been my doctor for over 20 years. He is an exceptional doctor who is ethical, professional, patient, considerate, and very concerned about his patients' concerns. He orders necessary testing and analyzes results prior to determining the best treatment options. Dr Guerra is the "best-of-the-best" and very strongly recommended to whoever may be so fortunate see this review!

Dr Guerra has been my Gastroenterologist for over 15 years and as a retired RN I would place my care in his hands on any day. He has performed both Endoscopies and Colonoscopies on me multiple times and I have sustained no negative complication.He is very easy to talk to and explains things fully.

I have been a patient of Doctor Guerra's nearly 18 years. I first saw him as a favor for the Orthopedic Surgeon my mother worked for at the time. Prior to that he had a policy of not seeing patients under 18 years of age. I am forever grateful that he did as the Pediatric Gasteroenterologist had misdiagnosed Crohn's for 3 years. Dr. Guerra, I can say with all honesty, saved my life when he agreed to see me when I was only 16 years old.

Dr Guerra is nice and funny. The staff I saw that I can really speak highly of is the Nurse Practitioner, Karen Spencer. I would go back and request to be seen by her. Aside from that, staff is courteous and effective which makes things easier. Wait time can get long.

I went in for a routine colonoscopy, my first one. Dr. Guerra was very attentive, has a very positive and caring attitude, a great bedside manner and really listens. He explained what he saw in the photographs. When I went back for my follow-up, he explained the surgical options and what he would recommend and even wrote out notes for me to give to my surgeon. Not only is he a great doctor, but one of the nicest guys I ever met. I highly recommend him.
