Dr. Oliak is a board-certified, fellowship-trained, ASMBS Center of Excellence bariatric surgeon who has an established record (>2500 patients) of excellent patient outcomes.* Dr. Oliak offers sleeve gastrectomy, gastric bypass, and revisional bariatric surgery in Orange County, California.
About Dr. Oliak
Dr. Oliak’s #1 goal has always been to treat patients how he would want to be rated himself. The #1 thing Dr. Oliak would want if he were having weight loss surgery is a surgeon/program with a record of excellent, industry-leading patient outcomes.
The fact is, outcomes after weight loss surgery (weight loss, complications) are highly variable between different surgeons and programs – see outcomes page. Dr. Oliak’s goal has always been to be among the best when measured by his actual patient outcomes.
Dr. Oliak’s approach for achieving great outcomes is to prioritize quality surgery, quality patient care, and surgeon accountability.
Dr. Oliak has learned over his 15-year career that quality surgery and patient care take significant time and effort. It is much easier and faster to settle for average surgery and patient care, or mediocre surgery and patient care. Insurance pays the same regardless of the time things take, so speed and volume are frequently prioritized. In Dr. Oliak’s experience, working hard to achieve excellent outcomes is a very different approach than prioritizing speed and volume.
Dr. Oliak prioritizes quality surgery and patient care by, first and foremost, devoting the time it takes to do quality surgery and patient care – see our program page. Dr. Oliak also prioritizes using only experienced and proven team members – operating room team, anesthesiologist, surgical assistants. Finally, Dr. Oliak prioritizes doing most patient care (education, follow-up, support) himself rather than outsourcing these important tasks to others.

Of course all this means nothing if it doesn’t translate into excellent patient outcomes. To measure his success at meeting his goal of achieving great outcomes, Dr. Oliak closely tracks his patient data. This has been an important priority since starting his career in 2002, and he now has more than 2500 patients along with their operation and outcomes statistics in a large database.
Tracking one’s own outcomes seems like an obvious thing for surgeons to do. Most bariatric surgeons, however, don’t do it because it is time consuming to do, and it is not work that is reimbursed. Not knowing ones’ own outcomes statistics, however, results in a lack of accountability for performance, and a lack of incentive for improvement.
In the field of weight loss surgery, the operations (gastric sleeve, gastric bypass) are not standardized. This means that there is not agreement on how the operations should be done to achieve the best outcomes. Even for seemingly basic things, such as what diameter/volume/geometry to make the sleeve to achieve the best outcome, there is no consensus. Because of this, different surgeons do the operations in different ways.
Given this characteristic about weight loss surgery, and the fact that there is often little surgeon accountability for performance, and the fact that there is a financial incentive to prioritize speed and volume over quality, it is no surprise that there is a wide variation in patient outcomes (weight loss results, complication rates) between different surgeons and programs.*

More about our outcomes
Dr. Oliak was the first Orange County bariatric surgeon to complete a laparoscopic bariatric surgery fellowship, and one of the first Orange County bariatric surgeons to routinely perform laparoscopic gastric bypass surgery rather than open gastric bypass surgery.
Dr. Oliak has developed two successful center of excellence bariatric programs in Orange County, one at Chapman Medical Center, and one at Placentia-Linda Hospital.
Dr. Oliak has published numerous outcomes-focused research studies, including studies on the learning curve for laparoscopic bariatric surgery, studies on outcomes for higher BMI patients, and studies on outcomes for older patients. Dr. Oliak has published his research in numerous scientific journals and has presented his data at national and international surgical meetings.
Dr. Oliak is a sought out weight loss surgery expert. He is a bariatric surgery consultant and bariatric surgery expert witness for bariatric surgery malpractice matters. He has appeared on national television shows, including The View (video clip) and The Tyra Banks Show (video clip), and on local news stations, including KCAL and CBS.
Background – Orange County Bariatric Surgeon Dr. Oliak
Dr. Oliak attended college at Northwestern University in Chicago, where he obtained his Bachelor of Science degree in chemical engineering.
Dr. Oliak attended medical school at top-ranked Washington University School of Medicine in St. Louis. During medical school he decided that he wanted to be a surgeon, and continued on after medical school to a six-year general surgery residency at Harbor-UCLA Medical Center in Los Angeles.
It was during his 2nd year of residency that Dr. Oliak decided that he wanted to specialize in weight loss surgery. He found the field of weight loss surgery to be compelling. In no other field of surgery could one operation enable something as difficult and desired as weight loss, and improve or resolve a large range of medical problems. He also found that no other field of surgery had such happy patients!
During his residency in the late 1990’s, the most common weight loss operation was open gastric bypass. Laparoscopic gastric bypass was considered experimental. Dr. Oliak’s belief was that laparoscopic gastric bypass would eventually become the standard of care, and would revolutionize the field of weight loss surgery.
Dr. Oliak wanted to learn laparoscopic gastric bypass, so after residency training he continued on to a one year laparoscopic surgery fellowship at Hackensack University Medical Center in New Jersey. This fellowship was one of the first laparoscopic surgery fellowships in the country to focus on laparoscopic weight loss surgery.
After finishing his fellowship training Dr. Oliak returned to California to start his career as a Los Angeles and Orange County bariatric surgeon.
* Patient results vary after weight loss surgery. Individual patients can do better or worse than the average.
** Leaks can occur after gastric surgery. Past performance is no guarantee of future results. Orange County bariatric surgeon Dr. Oliak’s 0% leak rate statistic applies to primary (non-revision) sleeve gastrectomy, primary (non-revision) laparoscopic gastric bypass, LAP-BAND® conversion to sleeve gastrectomy, and LAP-BAND® conversion to gastric bypass.
