Patient Testimonials


Doctor Rosenfeld was very kind and explained every detail of the procedure to me. I highly recommend Doctor Rosenfeld and his very kind staff.

Dan Parks


I had been suffering for the last 5+ years with the ailment and [had] 2 surgeries which made it recur before I met Dr Rosenfeld. He is not only [a] compassionate and caring doctor but also very detailed in his analysis and explanation of what the problem is and the next steps. He generally goes in for surgery only when he is sure of where the issue is and what it is. Post operative [he was] extremely caring and helpful. In short he has been able to give me a successful year post my 3rd surgery and I hope it continues the same way!!

I was spraying a lot of blood like a sprinkler for 2 years when having a bowel movement. A big mess. Dr. Rosenfeld performed hemorrhoid surgery of the inner veins and solved this problem with great expertise and changed my life at 65 forever. He is a great man and doctor. Extremely knowledgeable and humble. If you know of any one with any problems in this region please recommend they contact him and get his advice. There are people out there you can trust. Dr. David Rosenfeld is one of them, very passionate and helpful. Thank you with all my heart and soul.

Our Mission

To provide the most up to date medical / surgical care with a 1940’s bedside manner. We work hard to make your experience as smooth as possible from scheduling appointments to check out.

Dr. Rosenfeld’s motto is, “if we treat every patient like a family member, each patient will get the best and utmost compassionate care.”

At the end of the visit, new patients receive a copy of their visit note and a pamphlet explaining the ailment and therapies. These easy-to-understand and informative papers are very beneficial as patients will, at their leisure, have the ability to recap the visit and the recommended treatments. By making the experience as pleasant as possible, we hope that our patients will open up to others suffering from similar ailments. This will help to increase awareness about anorectal issues and colon cancer screening.

As you can imagine, proctology is not a glamorous field so a good sense of humor is important. Most of Dr. Rosenfeld’s patients ask why he became a proctologist. His answer is simple. Regardless of the profession, in order to succeed we must, “start at the bottom and work our way up”.
