Dr. Oliak and his Orange County weight loss surgery program prioritize high-quality weight loss surgery (gastric sleeve, gastric bypass, revision operations) and comprehensive patient care (education, follow-up, support) to achieve great patient outcomes.*

Quality Weight Loss Surgery

Providing high-quality, evidence-based weight loss surgery to maximize weight loss and minimize complications is the foundation of our Orange County weight loss surgery program.*

Dr. Oliak’s #1 goal has always been to treat patients how he would want to be treated himself. This means providing the best surgery, the best patient care, and most importantly, achieving the best outcomes.*

To grade his success at fulfilling this goal, Dr. Oliak decided at the beginning of his career to closely track his patient/operation/outcomes data. He has been doing this now for more than 15 years, and has a giant database of more than 2500 patients.

By having the goal of achieving the best outcomes, and knowing in detail his own patient/operation/outcomes statistics, Dr. Oliak has been able to optimize his surgical and patient care technique over time to continuously improve patient outcomes.*

Dr. Oliak’s patients first approach and his strong focus on being accountable for his actual patient outcomes have resulted in a long record of excellent patient outcomes – excellent weight loss results and low complication rates.*
More about our outcomes

It is hard to overstate the importance of actual patient outcomes. Outcomes – weight loss results, complication rates – vary over a wide range between different surgeons and programs.*
Outcomes vary between surgeons
Why outcomes vary

To understand the magnitude of this variation, consider the recent 2017 study published in JAMA (Journal of the American Medical Association) entitled “Variation in Outcomes at Bariatric Surgery Centers of Excellence” (read abstract). In this study, the rate of serious complications within 30 days of weight loss surgery was found to vary 17-fold (yes, 17-fold), from 0.6% – 10.3%, across 165 bariatric surgery centers of excellence programs nationwide.

Comprehensive Patient Care

Providing high-quality, comprehensive, individualized patient care is the second important component of our Orange County weight loss surgery program. Quality patient care, like well-performed, evidence-based surgery, is an important determinant of patient outcomes after surgery.*


Surgery is ultimately a tool that will help patients to 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 priority of our Orange County weight loss surgery program. Education starts at the initial educational consultation, and continues at educational classes before surgery, educational 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. Dr. Oliak’s goal is to give prospective patients all the information necessary to make an informed decision about surgery. The educational consultation is free, and there is absolutely no obligation.

Medical Management

Good medical management before, during, and after surgery goes hand-in-hand with good surgery to prevent complications. Dr. Oliak considers good medical management to be just as important as good surgical management.

Good medical management before surgery entails optimizing patients’ medical issues, and ensuring that higher risk patients lose weight preoperatively. Preoperative weight loss has an impressive effect on lowering surgical risk. Good medical management during and after surgery entails effectively managing patients’ medical issues, and, importantly, proactively preventing issues from developing.*

Postoperative Follow-Up

Follow-up after surgery is necessary to help ensure that patients achieve good success.*

Our Orange County weight loss surgery program prioritizes frequent postoperative follow-up, particularly during the first year after surgery. Because patient behavior (eating and exercise habits) has a major impact on weight loss outcomes, frequent follow-up enables Dr. Oliak to assess patient behavior and weight loss progress, and to intervene as necessary to help ensure that patients ultimately reach their weight loss goals.*

Support after surgery

Support after surgery helps patients to stay on track with good eating and exercise habits. Dr. Oliak encourages patients to obtain outside support from family and friends, and from other sources like social media. Dr. Oliak provides support at postoperative education classes, follow-up appointments, and support group meetings. Support group meetings are held once every three months.
