Our Orange County Weight Loss Surgery Program


Our program is designed to guide you through the entire weight loss surgery process, from learning about surgery, to obtaining insurance authorization or financing, to achieving the best weight loss results possible. The key elements of our program are service, education, surgery, and support.

  • Service
    Our friendly, knowledgeable staff is dedicated to serving you. Our first goal is to educate you about surgery so you can make an informed decision whether surgery is right for you. Our second goal, if you want to proceed, is to guide you through the insurance authorization process. After surgery our staff remains actively involved to help ensure that you achieve your weight loss goals. We are confident you will find our staff to be readily accessible and always helpful.

  • Education
    Weight loss surgery is best viewed as a tool to help with weight loss. For the operation to be as effective as possible it must be used appropriately. Our education program will help you to understand the operation and the behavioral changes necessary to achieve weight loss success.

  • Surgery
    Providing quality surgery is the foundation of our program. Dr. Oliak is a recognized expert in the field of laparoscopic weight loss surgery. He has performed more than 1750 laparoscopic weight loss operations (>1100 gastric bypass, >600 LAP-BAND®) since 2002, and his outcomes rank among the best outcomes published worldwide – see his LAP-BAND® outcomes (weight loss results and complication rates) and his Gastric Bypass outcomes (weight loss results and complication rates) on this website.

  • Ongoing, Personalized Support (read more)
    The key to achieving great weight loss results after surgery is establishing new eating and exercise habits. Our support program, which stresses education, frequent follow-up, and ongoing personalized support, helps patients establish healthy habits, and is the #1 reason for our excellent weight loss results.

Dr. Oliak’s office staff was very professional and set me up for an orientation. During the orientation, what stood out for me was Dr. Oliak’s statistics (which were left out in many other presentations), his experience, the friendliness of his office, and his strong interest in his specialty.
