Bengt F Pehrsson, MD

Great doctor. He is definitely very very experienced. In fact, I am surprised that he is still practicing. However, he is very down to earth. Very patient and takes his time to answer all your questions.
You won’t go wrong with this surgeon!

Sadly, I can only give 3 stars. I had gastric bypass surgery with Dr. Pehrsson in 2010. I went in feeling very prepared, thanks to the quality pre-​op nutritional education that his office requires. My surgery went well, I was in the hospital 24 hours total with no complications. Sounds good, right? Several follow-​up visits in the first year, all good. At the one year anniversary, I received lab orders in the mail in advance of my appointment so that I could have them completed to review with the doctor during my appointment. Everything was still looking good and after that, I was freed of follow-​up appointments for another year. At that point, I figured that I would have regular annual check-​ups with Dr. Pehrsson’s office for life, because that is what I had read about gastric bypass. When my two-​year appointment was approaching, I had not received a lab order in the mail, so I contacted the office. I was told that the doctor does not give the lab order until you come in for you 2 year «its his way of making sure you come in.» At my appointment, Dr. Pehrsson «shot the breeze» with me. Did not go into any in-​depth discussion to identify symptoms that I may have missed and at the end of the appointment, he handed me a photocopied list of labs and said «you can have your doctor order these, if you want.» If I want? All I have read and understood is that it is imperitive that you keep up with your lab work yearly because malabsorption issues could arise at any time! My three year anniversary came and went and I never heard another word from Dr. Pehrsson’s office (they had contacted me to make sure I scheduled all of the previous appointments. I have the distinct feeling that he needs statistics on weight and complications for 2 years post-​op, and after that he has no need for you. My suspicion was confirmed when a friend who had gone to surgeon in Orange County described the level of follow-​up care she was getting. So, I contacted this physician and asked if he would take over my follow up care. I got quite a battery of tests. I had experienced an increase in burping and felt some chest pressure recently, but was blaming myself, saying I must be eating too fast (even though I was eating RNY slow) This doctor asked the right questions, did the right tests and found out that I have h pylori, which could be very dangerous for a GBS pt if not treated.
Bottom line — great preperation and surgery — lackluster follow up.

Dr. Pehrsson did my recent emergency appendix surgery he was very nice and answered all my questions. I feel very lucky that I got him as my doctor. My incisions are so small they are barely noticeable. I went to my follow up appointment with him at his Pasadena office which was nice too but I couldn’t find it on Unilocal to review. I want to say Thank you very much Dr. Pehrsson

Dr. Pehrsson saved my life — I think that’s worth five stars, don’t you? Two years back I had perforated diverticulitis, needed emergency surgery, & he was the guy they brought in to do the job. Great surgeon, superb human being. So I dunno, how do you say thanks in Swedish!!!

I have known Dr. Pehrsson for 9 years now. He is the man that changed my life. Literally. He performed my gastric bypass surgery 8 years ago.
I first met him at a symposium that he and his office put on. At first I was a little hesitant because he seemed extremely serious and his thick German accent. He was actually a little scary mouthing off statistics and stuff all in a very monotone voice.
Fast forward to my consultation and the man had me in stitches. OMG! I realized that he is the funniest of the group. His colleagues all know this and let him play serious all of the time.
I did my research on him and realized that he is FACS accredited and, at the time, was the only doc in California that was doing revisions and was the one teaching other doctors how to do the Roux-​en-​Y.
I have referred countless amounts of people to his office and every one of them has been very happy. His office staff is a bunch of sweethearts! They are the kindest bunch. I can call them with questions and they will make sure I get the answer, whether they call me back or have a doc call me back.
Dr. Pehrsson does most of his surgeries laparoscopically which means a quick heal time. I was up and shopping at the mall 4 days after my surgery. :)
If you need a good gastro surgeon, see Dr. Pehrsson. Don’t let his demeanor freak you out.
