Our Orange County weight loss surgery program is based of the philosophy of prioritizing patients first. This means performing surgery and conducting patient care in the way that results in the best patient outcomes, and delivering a high level of customer service.*

Achieving Great Weight Loss Surgery Outcomes

The fact is, patient outcomes after weight loss surgery are highly variable between different surgeons and programs (more).* A record of excellent, industry-leading patient outcomes is the #1 thing that Dr. Oliak would want if he were having weight loss surgery, so achieving great outcomes has always been the #1 objective of his Orange County weight loss surgery program.
Our weight loss surgery outcomes

Key elements of our Orange County weight loss surgery program to maximize patient outcomes include:

Expert Bariatric Surgeon

Dr. Oliak is board-certified, fellowship-trained in laparoscopic weight loss surgery, and experienced (>2500 operations). Great outcomes, however, requires more than a well trained and experienced surgeon.*

Operations Limited to 2-3/day

Limiting operative volume allows Dr. Oliak to spend more time on each operation. More time enables more careful, more meticulous, and more exact surgical technique, which results in better and more consistent patient outcomes.* A typical gastric sleeve or gastric bypass operation (performed in the way Dr. Oliak would want for himself) takes about 2 hours. A more complicated operation (e.g. concomitant hiatal hernia repair, revision of band to bypass/sleeve) can take much longer. Often surgeons do 6 or more operations in a day – good for insurance collections, but not for patient outcomes.

Consistent OR Team

Dr. Oliak uses the same anesthesiologist and operating room team for virtually all operations at his main hospital, Placentia-Linda Hospital. He has worked with the same anesthesiologist for 15 years. Having the same team results in optimized, efficient operations, and prevents mistakes.* Most hospitals, unfortunately, won’t agree to giving surgeons the same team for all operations.

Consistent Surgical Assistants

Dr. Oliak always operates with the same surgical assistants. He has two – a general surgeon, and a physician assistant – and he has worked with both for >10 years. Having experienced assistants results in more efficient and higher quality operations.*

Patient Education and Follow-up

Dr. Oliak prioritizes comprehensive patient education and frequent follow-up. Education ensures that patients understand surgery, how it works, and what they need to do to avoid complications and maximize success. Frequent follow-up over the first year after surgery provides accountability, support, and intervention as necessary to help ensure that patients achieve their weight loss goals.* Surgeons often skimp on patient education and follow-up, preferring instead to do surgery – good for insurance collections, but not outcomes.

Continuity of Care

Dr. Oiak does all patient education and follow-up himself, with infrequent exception. He is also on call for his patients, with infrequent exception, 24-7. This continuity of care results in better patient care and therefore better outcomes than relying on others to do patient education and follow-up.*

Great Customer Service

Dr. Oliak’s 2nd goal is to provide excellent customer service. This means providing a pleasant, efficient, and convenient experience for patients. Our approach is as follows:

Excellent office staff

Our office staff, like Dr. Oliak, prioritize patients first. When patients are prioritized first, achieving good customer service is easy – the phone gets answered (even during lunch), calls get returned, things get done quickly, etc.

Dedicated surgical coordinator

Having a dedicated surgical coordinate gives patients one point of contact for the entire process of obtaining an insurance authorization, completing all necessary preoperative tests, scheduling all necessary preoperative visits, and scheduling surgery.

Easy appointment scheduling

Because we dedicate significant time to in-office patient care, we generally can schedule office appointments within 1-3 days.

Easy access to Dr. Oliak

Dr. Oliak is easily reachable after business hours by cell phone or text message.

Phone/email/text communication

Dr. Oliak and staff are happy to correspond with patients about scheduling, test results, questions, and issues by phone/email/text. Dr. Oliak can do preoperative and follow-up appointments by phone when necessary (e.g. when patients live out of the area).
