ABOUT
Meet The Doctor Behind Proctologist Preferred, Inc
Dr. Rosenfeld is a loving father to his 3 boys. Born and raised in Michigan his Midwest values (honesty, trust, dependability) are important to him. As family values are equally important, he left his practice of 7 years (2000–2007) at Cedars Sinai Medical Center to join Simi Valley Adventist Hospital in order to be closer to his family. He recently moved his practice again to Thousand Oaks to be even closer. He works hard to be a loving father, while striving to be the best, most up-to-date proctologist. Dr. Rosenfeld's motto is: "If we treat every patient like a family member, each patient will get the best and utmost compassionate care."

Practice Philosophy
Although my training in surgery and my subspecialty of proctology was based on Western Medicine philosophy, my practice approach includes a holistic ideology as well. All patients are different; therefore, the one-size-fits-all mentality is not the way to practice medicine.
I firmly believe in natural and conservative therapies for healing and reserve surgery for times when it becomes the best or only option. I begin therapy, when appropriate, with all-natural products to improve colorectal and anorectal health. These include unadulterated psyllium-based fiber, natural plant-based (bioflavonoid) antioxidants to shrink hemorrhoids, probiotics, prebiotics, L-Glutamine, and Aloe Vera extract to improve intestinal health and encourage more water intake.
Before determining if hemorrhoid surgery is necessary, I can painlessly treat internal hemorrhoids in the office as a first-line therapy. Most patients respond well to therapy with natural supplements, helping avoid surgery. When surgery or procedures like colonoscopy are needed, I use the latest proven technology and techniques. The best way to offer effective, caring, and nurturing care is by listening to patients, making a diagnosis, and using both holistic and Western medical approaches when appropriate.
