Dr Rosenfeld is a rare combination of knowlege, experience and empathy. He came highly recommended to me via my family practioner.
He and his office staff have been instrumental in providing support after he recently discovered my colon cancer via a colonoscopy he encouraged me to have. He was forthright in explaining the implications of my tumor and he made knowledgeable suggestions, recommendatiions regarding what I needed to do next. He and his staff have gone out of their way to make this difficult time a positive transition and they continue to do so!
Dr. Rosenfeld does not take our insurance at this time but he was very fair in his charges and the office staff is very up front about how the charges are handled. They handled all my insurance billing so I could be reimbursed ASAP!

I could not have been happier with the work Dr. Rosenfeld did on my external hemorrhoid. The hemorrhoid wasn’t painful, but having it back there didn’t quite gel with my overall self image. I went to his office for an initial check up and he told me he’d have to excise it to get rid of it. He said it would be like going to the dentist office.
Well, I went home and surfed the internet. Bad idea. It’s filled with horror stories from around the globe of people with similar procedures, leading to everything from infection to their anuses practically falling off. So I didn’t do anything for about it for nearly 8 months. Depression set in and I gained weight. Finally I decided to do it. The worst part of the procedure was the shot of lidocaine into the hemorrhoid, which I barely felt. It was the same feeling that you get at the dentist office when they numb your mouth. When the site was sufficiently numb he cut the little bugger out, even showing it to me afterwards. Gross, thanks Dr. Rosenfeld.
I was told by the internet that the time after the procedure would be where the real fun started. Dr. Rosenfeld confirmed this to a degree but didn’t think I’d have too much trouble. I left the office and went straight to the pharmacy to get my painkillers. I went home and waited for that first awful bowel movement, when it came the dread set in, but I sat on the throne and waited. To my utter amazement I did my business without any pain. NONE! That continued throughout my recovery and I still have all of my painkillers. The site, at first pretty swollen and gross, healed very quickly and was nearly healed by the time I had my post-op check up three weeks later.
Today, you can’t even notice anything was ever wrong down there. The only regret is I didn’t go through with it sooner. I am truly blessed that I found a real doctor out in Simi Valley. He and his staff are the real deal. And we are all blessed that we live in an age where medical maladies like hemorrhoids are easily treated and that doctors like Dr. Rosenfeld are as knowledgeable and skilled as they are.
And one more thing, because I’m a student the office gave me a pretty generous discount. That was icing on the cake.

Complete professional, great staff and wonderful results!! I had a perirectal abscess in March which the doctor diagnosed immediately upon seeing me and then treated. I felt 100 times better that same day and was on the road to recovery. He checked on me many times after the treatment and so did his staff. He really cares and he spent alot of time with me going over everything about my condition. I feel lucky to have found Dr Rosenfeld since I am not originally from the area. My dad is a radiologist and met Dr Rosenfeld and was also very impressed. He is truly a specialist in his field and I would highly recommend him!! Thanks again Dr and God Bless!!

A great doctor with a fantastic personality.
No need to be scared or nervous knowing that you have a doctor that truly cares and can communicate with you.
I wish there were more Dr’s like him.

Dr. Rosenfeld is an amazing doctor. He has a great bedside manner and he really listens to his patience’s.
I began to see doctor Rosenfeld little over a year ago and at the time I was not able to sit due to the excruciating pain in my bottom. I had this pain in my bottom for almost ten years, image not sitting on your bottom or when you did sit you need a donut (come to find out DONUTS are just for eating) with lots of ice. I could only sit on the donut for short periods of time not even a half an hour that was to long…It was very difficult being me, carrying and transporting ice packs, pillows time restraints, oh no!!!!. So I was so glad to find Dr. Rosenfeld.
On my first visit with Dr. Rosenfeld, he was able to diagnose that I had tension butt ache (go figure what the heck was that) and hemorrhoids. He treated those in his office and a few days later I felt a little better but the symptoms kept coming back. I continued to complain about the same thing. Because I have a lot of sensitivities to drugs I was unable to take anything that may have helped this problem. Since drugs where not an option Dr. Rosenfeld suggested I consider a procedure to simulate my muscles to relax the tension butt ache. I went ahead with this procedure in December of 2012. I felt amazing for the three weeks that I had the device in, when the device was taken out the tension butt ache was gone but not the hemorrhoids. So I continued to see Dr. Rosenfeld so he could treat the hemorrhoids in his office. In May of 2013 he suggested I have hemorrhoid surgery, he said he uses this new Doppler technique and he is one of the only doctors in southern California that does this procedure…wouldn’t knowing that make you want to run right over to his office. That is what I really like about Dr. Rosenfeld is he is always looking for those new state of the art techniques to help his patient, besides he has a great sense of humor.
So in June of 2013 I agreed to the surgery. I will not kid you hemorrhoid surgery is a little rough at first but PLEASE do not get discouraged and listen to everything Dr. Rosenfeld tells you, and in the end you will be very very happy with results.
I told Dr. Rosenfeld’s office that I wanted to send them a picture of me doing a back flip in a pool SO my best back flip story I can give them was 6 weeks after the surgery my husband and I went on 3,200 mile road trip and I was able to sit and help drive as well. This is something I would have not been able to do a year ago.
Thank you and your amazing staff for all your help.
