The #1 goal of our Orange County weight loss surgery program is to achieve great outcomes for our patients. We do this by prioritizing quality weight loss surgery (gastric sleeve, gastric bypass, revision bariatric surgery), and comprehensive patient care (education, follow-up, support).

Quality Weight Loss Surgery

Providing quality weight loss surgery is the foundation of our Orange County weight loss surgery program. In our experience over 15+ years, this is the #1 key to achieving great patient outcomes.*

What does providing quality weight loss surgery mean? In our program, it means 3 things:

Providing quality weight loss surgery means always prioritizing proven surgical best practices, always prioritizing careful and meticulous surgical technique, and always prioritizing exactness (e.g. exact sleeve size/shape, exact staple line contour, exact bypass pouch size/shape, etc.). To accomplish all this, it is necessary to allocate sufficient time for surgery – 2 hours for each operation, often 3+ hours for revision surgery, total of 2-3 operations per operating day.

Surgical Team
Providing quality weight loss surgery means always using an experienced and proven operating room team. The two most important team members, after the surgeon, are the anesthesiologist and the assistant surgeon. Dr. Oliak always uses the same anesthesiologists and assistant surgeons. He has worked with his 2 assistant surgeons, and his main anesthesiologist for more than 10 years.

Surgical Facility
Providing quality weight loss surgery means maximizing safety by doing all operations in accredited bariatric surgery center of excellence hospitals, not outpatient surgery centers.

Patient Outcomes
The best measure of quality of surgery, of course, is actual patient outcomes – weight loss results and complication rates. Read about our record of excellent, industry-leading patient outcomes on our outcomes page.*

Comprehensive Patient Care

Providing high-quality, comprehensive patient care (education, follow-up, support) is the second priority of our Orange County weight loss surgery program. In our experience, quality of patient care, like quality of surgery, is a key determinant of patient outcomes after surgery.


Surgery is 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 purpose of follow-up is to provide assessment, education, and guidance to help ensure that patients achieve their maximal possible success after surgery. Appointments are scheduled as frequently as necessary to accomplish this.

Follow-up appointments are scheduled frequently early after surgery (every 2-4 weeks), and less frequently once appropriate weight loss progress is established (every 6-12 weeks). After weight loss is complete (1-1.5 years), follow-up appointments are typically scheduled every 6-12 months.

Support After Surgery

Support after surgery is important to help patients establish and maintain appropriate eating and exercise habits after surgery. Dr. Oliak provides support via follow-up appointments and support group meetings. Support group meetings 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 close family members to preoperative and postoperative teaching classes, follow-up appointments, and support group meetings.
