Dr. Michael Feiz, M.D., FACS

From the initial consultation to the actual surgery date, to the follow up visits since my surgery, I have had the most positive experience. Dr. Feiz is a skilled surgeon. He explained everything and reassured me, answered all my questions and addressed my concerns. I was never rushed and received the best care. My expectations were met! I’ve had zero complications and I know that I chose the right Doctor.
His office staff was very helpful and guided me through the insurance process. I would highly recommend Dr. Feiz and I’m very thankful that he has helped me transform my life.
5 stars, A+++

I lost 55 pounds with Dr.feiz. He was amazing with me and really cared about all my needs. I would recommend him to everyone who is looking to have weight loss surgery.

Dr Feiz was an excellent doctor. He is a wonderful surgeon. We have had 2 members of our family do different procedures and we are very very happy with the results. He is a very informed doctor and explained everything to us a number of times. He was always available via cell phone at all times.
My husband had the surgery in December and Dr Feiz was there and his staff were excellent and we would very highly recommended him for any procedure you may need. His surgery center was very well staffed and they were also excellent in every way.
My family are mostly doctors themselves and we have very high expectations of other doctors. So if we are recommending Dr Feiz that means he is really an excellent doctor and he has an amazing staff that follows you every step through the process.

I moved to LA about 18 months ago and started seeing Dr. Feiz on commercials. My previous doctor had told me it could take multiple surgeries to have the band removed and converted to a different surgery. After meeting with Dr. Feiz I was immediately put at ease that he had performed Band conversion to Sleeve Gastrectomy many times and was confident that he would be able to do it in one surgery. Of course there are never any guarantees until they are in there.
I scheduled my surgery and have to say I was never stressed at all even the day of surgery about having any issues. Dr. Feiz made me feel like he would take care of me like he would his own sister.
The surgery was completely opposite of my Lapband surgery. I had no complications, and was up walking every two hours as soon as I was out of recovery. I truly had minimal pain thru out the whole experience and only took pain medicine for about 3 days once I got home from the hospital. It was truly an AMAZING Experience!!!
I would highly recommend Dr. Feiz to anyone who was considering bariatric surgery. He is truly a gift from God and worth the drive no matter where you live!!!

Dr Feiz and his top-​notch family/​team have made me feel whole for the first time in my life. My mind & body are connected like I have never felt. I had the lap band placed in 2008 in Kansas by a different surgeon. I had nothing but complications and misery with the lap band. It was a complete failure & slowly rotting away, and certainly I never got the results I wanted. I am now 6 weeks out from the emergent surgery performed by Dr Feiz. He saved my life & gave me hope & a new life. I’ve lost 25 pounds & I feel one million percent better, & I’m not starving or hungry or in pain anymore. My knees are already improving along with my stamina, no more heartburn or cramping or bloating. Office staff are responsive & friendly. Everyone is attentive & loving, genuine & take time with you. Larry is great – he gets it & is an asset to the team. I can’t say enough how grateful I am. 5 stars is not enough!!!

My mom has battled weight loss for as long as I can remember. She heard of Dr. Feiz one day while watching television and contacted his ranch Cucamonga office soon after. Everything fell into place wonderfully and she went in for surgery last week. She is already 20 pounds down and couldn’t be happier and has nothing but nice things about him and his staff. I have never seen her this confident and excited!

I visited Dr Feiz’s Rancho Cucamonga office last week for a weight loss surgery consultation. First impressions are everything and his office hit the mark. The waiting areas are beautiful and the staff is fantastic. Everyone was pleasant and knowledgeable. I left the office knowing exactly what would be expected of me, how long the process would take and exactly what my insurance does and does not cover. The initial consultation was conducted by a DOCTOR — not by a staff member or coordinator. When considering a life changing surgery, speaking with an actual doctor is so comforting. The doctor I met with was Dr Sean Rim. His demeanor was so awesome — calm and comforting but extremely knowledgable — and did I mention he’s adorable? Having a handsome doctor calm your fears is always helpful! I decided to go ahead with the procedure and so far any member of the staff who has contacted me has been amazing. Very professional and courteous and never in too much of a hurry to answer my questions or address my concerns. I’m excited and nervous at the same time but so far I can’t say enough good things about Dr Feiz, Dr Rim and the staff at this location!

The staff and patient coordinators couldn’t have been any more accommodating and the office is beautifully kept. Had my consultation and was looking forward to my procedure here. Something came up and I chose to return (for the 3^rd time) to The Ariel Center in Tijuana (also a center of Excellence) Lysette was extremely helpful and very knowledgable of all the procedures that are offered here!

Dr. Feiz and his staff are AMAZING. I had completed 6 months of trying to lose weight on my own with another surgeon who took an additional 4 months to get his paperwork together for insurance approval. I finally had a surgery date of 3÷31÷15 and a week before surgery he told me I had to lose 15 pounds. He said I have made his job 3 times harder because I had scar tissue from my lap band, my liver is probably enlarged and I’m overweight. I left mortified. I called Dr. Feiz office and in 12 days had the surgery and I cannot say enough great things about them. He and his staff are so informative, attentive and caring.

Dr Feiz is a wonderful Dr. The staff at ASI goes above and beyond what your normal office staff would do. They are 100% ethical and moral and Larry is very helpful in answering any questions that I have. There are many locations which is convenient with my schedule

Hello I’m Robert and I would like to tell you about my experience with Dr. Feiz. First let me start with that I have done my research on weight loss surgery. After all my research last year I made my decision to go with Dr. Feiz. I went to his office in Beverly Hills over a year ago and sat down for the free seminar which was very helpful. Larry one of Dr. Feiz’s staff was very helpful and full of information and answered all my questions.
I had my surgery less than 4 months ago and I feel GREAT!!! I have lost over 80 pounds now and 8 inches in waist.
Now let me talk a little about the surgery. I had the surgery in Huntington Beach at a surgery center and the staff was so great. They made me feel so comfortable. The surgery was quick. Lol I was knocked out with anesthesia after waking up I feel some discomfort but not too bad. I was transported to a surgery aftercare in Beverly Hills. Which was really great as well. Nice staff.
I have to say my whole experience was great. Dr. Feiz and his staff have been awesome and so helpful. A special thanks goes to his staff. All of them have been so great. Dr. Feiz would take time to call me if I had any questions. They have taken care of me and I’m glad I chose Dr. Feiz and associates. If there was 10 stars to rate them they would get them from me.
If anyone would like to talk or have any questions please Dr. Feiz’s office and ask away. They have my info you would like to hear more about my experience.

Great Doctor!
