Dr. Oliak is committed to achieving the best possible outcomes for his patients by providing excellent, expertly-performed weight loss surgery (gastric sleeve, gastric bypass, revision operations), and high-quality patient care (education, follow-up, support).*

Expert Weight Loss Surgery

Providing excellent, expertly-performed weight loss surgery, done in a way that will result in the best possible patient outcomes, is the foundation of our Orange County weight loss surgery program.*

The challenge of doing surgery in this way is the fact that there is not industry consensus on what constitutes the best way to do the operations. For the gastric sleeve operation, for example, there is not consensus on the fundamental details of how the sleeve should be constructed, such as what dimensions/shape/size the sleeve should be, and where exactly the staple line should be placed.

Because of this lack of consensus, different surgeons do the operations in different ways. The importance of this is that the details of how the operations are performed have a major effect on patient outcomes – weight loss results and complication rates.
More about outcomes

Dr. Oliak’s approach, since starting his weight loss surgery career in 2002, has been to closely track his patient outcomes, and then work hard to do the operations in the way that results in the best weight loss results and the lowest complication rates.*

Dr. Oliak’s outcomes-focused approach has resulted in a record of weight loss and complication statistics that rank among the best in the weight loss surgery field.*

Patient Care – Education, Follow-Up, Support

Providing high-quality patient care (education, follow-up, support) is the second priority of our Orange County weight loss surgery program. Quality of patient care, like quality of surgery, is an important determinant of patient outcomes after surgery.*


Surgery is ultimately a tool to help patients lose weight and maintain weight loss over time. The purpose of education is to ensure that patients understand surgery, how it works, and how to use it most effectively.

Education is an important focus of our Orange County weight loss surgery program. Education starts well before surgery at the initial educational consultation, and continues at educational classes before surgery, at nutrition classes after surgery, and at follow-up appointments after surgery.

The initial educational consultation is a great first step for prospective patients to learn more about surgery and our Orange County weight loss surgery program. The educational consultation is free, and there is absolutely no obligation.

Postoperative Follow-Up

The primary purpose of follow-up is to help ensure that patients achieve their maximal possible success after surgery.

Typically follow-up appointments are scheduled frequently during the early months after surgery (weekly, then biweekly, then monthly), and then less frequently (every 3 months, then every 6 months, then yearly) according to individual patient needs.

During follow-up appointment Dr. Oliak first assesses weight loss progress and eating/exercise habits, and then makes recommendations and proposes goals to achieve for the next scheduled appointment.

Support After Surgery

Support after surgery is important to help patients establish and maintain good eating and exercise habits after surgery. Dr. Oliak provides support via follow-up appointments and support group meetings, which are held monthly at Placentia-Linda hospital.

Dr. Oliak also encourages patients to seek outside support – family/friends, social media. To help foster outside support, Dr. Oliak encourages patients to bring key family members to preoperative and postoperative teaching classes, follow-up appointments, and to support group meetings.
