Peter O'Brien Bariatric Surgeon M.D.,F.A.C.S.

I highly recommend him to anyone. he was very kind and supportive. i visited with two other surgeons before him. i also knew a nurse from the surgery room and she said that he was the best. Sioux Vally hospitial was also very good.

Dr O'Brien is very straight forward, but seems to genuinely care about you. Didn't have a lot to say that first visit, but his staff has been great. I tend to like his quiet, formal attitude, makes me feel like he's serious about his work, which is what I want! :o)

A bit cold but businesslike and competent.

My meeting with Dr. O'Brian have been short. I have had no reason to change my impression of him.

The staff seems to be competent and efficient.

I would have liked to have been able to have longer meetings with him both before and after surgery.

There is a structured aftercare program and patients are strongly advised to participate.

He explaned what could go wrong, the remedial actions that might be necessary and the odds of different outcomes.

I would let him do surgery on me again if I needed it.

While bedside manner is nice I would put a higher value on surgecal competence.

My impression of Dr O"Brien has been great so far. He answered all of y questons and was extremely thurough w/ his answers. His staff has been very quick, kind and helpful as well.

He does tend to lean toward the Lap-Band, but will advise which procedure will work best for you as an individual.

He informed me of my personal potential risks that are catered to my current health issues for both procedures.

I thought he was very knowledgable, nice and helpful. He figured I wouldn't be approved for the surgery because of the insurance plan I had, so that was a little discouraging. He is somewhat quiet and not forthcoming with info unless asked. He stressed that aftercare was very important to followup with. His nurses are the best. They are very knowledgeable and if they do not know the answer they do get back to you with it.

I thought Dr O'Brien seemed to be a very knowledgeable physician.I trust him.


I have only met with him once.

The office staff are great.I have spoken to Aurie a couple of times and she has been very helpful and cooperative.

I think he is very good at what he does and has much experience in gastric surgery.
The aftercare has been emphasized int the informational pamphlets very much.
Yes,from reading the information given to me there are regular followup care appointments to make sure everything is going the way it should.

I would rate him overall as 8 out of 10.He is nice but does not have the warm personality I would like.
Definitely,surgical competence is the most important thing, but I need to be able to feel comfortable discussing my concerns with my sugeon. I think I have both with Dr O'Brien!

First impression of Dr. O'Brien was he knew his stuff, to the point and helped me make up my mind on which way to go.
Impression has not change.
The office staff is GREAT... VERY helpful and very nice.
Future patients should see him twice to get a get feeling on him, if your having a hard time making up your mind. But I think you will like him from the start, you don't get a smile from him right away, my wife thougth he was a bit cold, but I liked him from the start.
Aftercare is a must, yes there are structured aftercare programs, also a support group on the web and meeting at the hospital or close by.
Was told of the risks, but the risks of not having it is higher, at least to me.
Rating him from 1 - 10 I'd give him a 10.
I think surgical competence and bedside manner is a must.
This is just my personal impressions of my own personal experience and I'm making no statements about what other people may experience.

My first impression was he is brief and efficent. He will stick around if you have questions and has no trouble answering them. I have never had to wait long in his office for my appointments. Everyone has always been friendly. I am very impressed at how much he comes and sees you in the hospital. Very early morning, late morning, and late afternoon. Much more than other Dr.s in my opinion. Also took my fever serious and would rather be cautious then let me out with it. He also came and visited with us in the pre-op room. I would recommend him highly. I think he is very surgically competent, and great on following up after the surgery!
Thank You! Dr. O

Dr. O'Brien was very professional. I have only meet him once and have been dealing with his staff since. The staff was very friendly and responded to my phone quickly. They have answered any question that I had. It been pointed out to me that after care is a requirment. There is a set program to follow before and after. I give a thumbs up for Dr O'Brien and his staff.

MY FIRST IMPRESSION WAS HE WAS VERY PATIENT AND EXPLAINED THE RISK AND ADVANTAGES OF THE DIFFERANT TYPES OF PROCEDURES.

MY OPINION OF HIM IS STILL GOOD I HAVE ONLY HAD THE ONE VISIT SO NOT ALOT TO BASE IT ON.

THE STAFF IS VERY PROMPT AND HELPFUL WITH APPT AND INSURANCE INFORMATION.

HE ADDRESS THE RISK AND SIDE EFFECT OF EACH PROCEDURE AND ADVANTAGES WELL.

I FELT HE WAS VERY COMPETENT AND THROUGH.

SEEMED VERY KNOWLEDGEABLE BUT I STILL WANT TO CONTACT SD BOARD OF HEALTH TO SEE IF ANY COMPLAINTS OR PROBLEMS.
