William Arnold Bariatric Surgeon MD

Biliopancreatic Diversion with Duodenal Switch




Awful doesn't come close to describing Dr. Arnold and his staff. They will make you wait for months and then when you arrive, they won't tell you that you are not meeting with a licensed doctor but instead "student doctors". I had no clue the person treating me and scheduling me for surgery was not a licensed doctor until he was unable to answer my questions regarding my condition and surgery. When you complain Dr. Arnold will cancel your surgery and prolong treatment of serious health issues. As a result, I had to file a complaint with the Arizona Medical Board. Although you will not be seen by Dr. Arnold, he has no problem billing your insurance company. Do yourself a favor and seek a doctor that respects you as a person as well as your rights and who doesn't see you as guinea pig he can cash in on. Tenet Health is the parent company of Abrazo, and they are absolutely useless in dealing with any issues.

Dr Arnold is such a sweet heart! He really cares for his patients. His Office staff is really helpful. They worked hard for me to be able to have the surgery. After my first one on one meeting with him my mind was at ease and i knew that he was the right surgeon for me. He is kind of young but is still very knowledgeable. He didn't make me do any unnessecary pre-op testing only what was needed. I didnt have to jump through any hoops and his office staff did most of the work. I will forever be grateful for Dr. Arnold his attention to detail and his encouragement. He came to my hospital room everyday sometimes twice a day to check on me. He is intelligent and down to earth. He has a passion for what he does and it shows every time i talk with him. Good thing is that he has virtually no waiting list. If your in AZ looking for a surgeon CALL HIM!!!! I put his info on the top of my profile
