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.”
Although my training in surgery and my sub specialty 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 time when it becomes the best option or is the only option. I begin therapy, when appropriate, with all natural products to improve colorectal and anorectal health. These products included unadulterated psyllium based fiber, natural plant base d(bioflavonoid) antioxidants to shrink hemorrhoids, probiotics, prebiotics with other natural ingredients like L-Glutamine and Aloe Vera extra for improving intestinal health and encourage more water intake.
Prior to determining if hemorrhoid surgery if necessary, I can painlessly treat internal hemorrhoids in the office as the first line of therapy. For the majority of patients therapy with all natural supplements work very well to avert surgery for the issue. When surgery or a procedure such as a colonoscopy is necessary, I use the latest proven technology alone with the newest proven methods available. The best way to offer effective, caring and nurturing health care is to listen to the patients, make a diagnosis and, when appropriate, use both a holistic practice in conjunction the Western practices of Medicine. Both philosophies have their advantages and when used together can be more effective than done individually.
