Mission Statement

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”.

Doctors Care – The System Doesn’t!

Doctors today are often accused of being uncaring. It is what we hear on the television and cable networks and what we perceive in the busy waiting room as we wait to see the doctor to get only for a few minutes of their time. While having lunch in the […]

When a pseudoscientific remedy makes a patient feel better

I was trained in Western Medicine where surgery and pharmaceuticals were all that was important. Over the years my beliefs have changed and so have those of the medical community. In many ways Western medicine is adopting the beliefs of the Eastern medicine philosophies which I feel is a big […]
