Dr. Rosenfeld's bio

This content was provided by Dr. Rosenfeld "Midwestern Values Dr. Rosenfeld is a husband to his wife, Shaina, and a father to his 3 boys, Charlie, Jack and Henry. 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 works hard to be a loving husband and 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 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 option or is the only option. I begin therapy, when appropriate, with all natural products to improve colorectal and anorectal health. These products include unadulterated psyllium based fiber, natural plant based (bioflavonoid) antioxidants to shrink hemorrhoids, probiotics, prebiotics with other natural ingredients like L-Glutamine and Aloe Vera extract for improving intestinal health and encourage more water intake. Prior to determining if hemorrhoid surgery is necessary I can painlessly treat internal hemorrhoids in the office as the first line of therapy. For the majority of patients therapy along 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 along 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. Professional Expertise Dr. Rosenfeld finished his fellowship at USC in proctology and colorectal surgery in 1998. Dr. Rosenfeld specializes in proctology (butt doctor) in California. He is an expert in diagnostic colonoscopy, surgical colonoscopy, hemorrhoid therapy, hemorrhoid surgery, benign and malignant anal diseases, pilonidal cyst disease, and rectal prolapse (in elderly). He has been in private practice since 1998. He spent 7 years at Cedars Sinai Medical Center. During his tenure he was an active professor in the colorectal surgery fellowship program. Dr. Rosenfeld is now on staff at Simi Valley Hospital, Aspen Surgery Center and is also a Clinical Assistant Professor at County Hospital USC. He is double board certified in general surgery and colorectal surgery/proctology. Publications Dr. Rosenfeld published a chapter on laparoscopic colectomy [Modern Management of Cancer of the Rectum: Chapter 9: Laparoscopic Resections for Large Bowel Malignancy, Springer-Veriag Publications, London]. His paper, "Intraoperative High Resolution Anoscopy: a minimally invasive approach in the treatment of patients with Bowen's Disease and results in a private practice setting" was accepted for publication in The American Surgeon 2007;73:1279-1283. Bowen's disease is the same as high grade anal dysplasia."
