Phoenix, AZ |
In July, I will be celebrating 3 years with my lapband! It has not been the easiest process, and is still something I work hard at every day. With the help of WLIA I was able to say goodbye to diabetes, and live a healthier lifestyle. Thanks Dr. Orris and team.
Scottsdale, AZ |
The Dr's and the staff at WLIA have been great. They are very helpful and knowledgeable about the entire process. I would recommend them to anyone who is considering. Thanks
in Tempe, AZ |
A co-worker referred me to WLIA and spoke so highly of the staff and Dr. Orris that it convinced me to make the initial appointment that same day. The staff was always very professional but also welcoming and friendly. Most have worked with Dr. Orris for many years, are very knowledgeable and it shows that they share his mission. All of my surgical and financial questions were answered thoroughly, without feeling rushed or scripted. I wish I had known about WLIA years ago!
in Mesa, AZ |
Highly recommend! My husband and I chose a consultation with WLIA for lap-band surgery based off the recommendations from other nurses and they were right! From the moment we walked in the door, you could see from all the little touches that this doctor's office was different. About half of the chairs in the lobby were build for larger folks which was a relief for anyone that has had the horrible experience of trying to be comfortable in a chair that is too small. There were pictures of success

Dr Orris and his staff were great to work with through this entire experience. With every issue I faced, they were there to help me through it. They listened to each concern and answered all my questions. I had my surgery in April and I feel fantastic. I am down 30 pounds! My blood pressure is down, my back is feeling so much better and I have lots of energy. Thank you Dr Orris.

Dr. Orris and his staff are wonderful. I will recommend him to everyone I know. He is truly amazing. He's very personal and professional.

Dr. DeBarros is the most amazing doctor. I had my surgery done in 2007 and have never regretted a day of it. I can not say enough about Dr DeBarros and Dr. Orris and Mike Murphy RD and staff, they are very caring and want you to succeed in your weight loss journey regardless of what surgery you have done there (Lapband, Gastric Bypass, Sleeve). I had the lapband done and I still go in on occasion to follow up or just to show them how well I'm doing. I am treated like family and if I have any

For many years I have tried and failed to lose weight so in desperation I decided to turn to weight loss surgery. After doing some research online I decided that Weight Loss Institute Of Arizona was right for me. I met with Dr. DeBarros and Dr. Orris at my initial consultation. They were both friendly, professional, answered all of my questions, and alleviated any concern I had about the procedure. I was very satisfied with the care that I received and am greatly looking forward to my procedure.

I've been coming to WLIAZ for the last two years and i couldn't be happier. Everything has been easy peasy. Mike and Dr. Orris have been very reachable and make me feel like I am not just a number. Also, the staff have been so professional and kind. Thank you!

WLIA is more than amazing to work with. They are so prepared to answer every question and made me feel so comfortable with my decision to move forward with Gastric Sleeve surgery. My surgery was Nov. 13, 2015 performed by Dr. Michael Orris. He did an outstanding job. I've had to call his team at WLIA several times with questions the week following surgery and they were so kind and helpful. Knowing now what I know I would do it over and over again. I highly recommend WLIA. I am down 65 pounds.

Dr. Orris is such a great doctor!! He has answered all of my questions and I can't wait to get surgery!!
in Goodyear, AZ |
Dr. Orris really cares! His staff went above my expectations with approval, scheduling, and nutrition! Thanks.
in Tempe, AZ |
Dr. Orris & staff have always been helpful and courteous. They worked with me on billing through a job/insurance change to make sure there would be no surprises. They were great about helping me with dieting/exercise to lose the weight I needed to pre-surgery. Surgery went smoothly and recovery was easier than I expected it to be. I would strongly recommend Dr. Orris and staff for your weight loss journey!
in Buckeye, AZ |
I decided last August to have weight loss surgery and chose WLIA on the recommendation of a friend who had the Lap Band procedure with them the prior December. I have been pleased with the staff and my surgeon must have done a FANTASTIC job because I had a very easy recovery and absolutely no complications. The staff is great as well!
