Weight loss surgery done right
Our Orange County and Los Angeles County weight loss surgery program offers weight loss surgery done right. We welcome patients from across the country and around the globe, as well as low BMI patients (BMI 30-34.9).
Since 2002, our patient outcomes rank among the best in the weight loss surgery field.* How do we know? Dr. Oliak closely tracks his actual patient outcomes (weight loss and complication statistics).
Better weight loss than the industry average*
Leak rate for gastric sleeve (Industry average 1-2.4%)*
Leak rate for gastric bypass (5-10 times less than the industry average)*
* Individual patient results vary. Statistics based on comparison between Dr. Oliak’s average 2yr, 5yr, and 10yr %EWL (percent excess weight loss) results and leak rates for all laparoscopic gastric bypass and gastric sleeve operations performed 2002-2019, and average weight loss results results and leak rates published in large review studies.1-9
How we do weight loss surgery at the Oliak Center
Our formula is simple.
Superior operations + Outstanding patient support + Excellent hospital partners = Successful surgeries
Dr. Oliak performs excellent surgeries based on data
The gastric sleeve and gastric bypass operations are not standardized across the weight loss surgery field. Different surgeons do the operations differently (and have different skill levels). That means outcomes vary from surgeon to surgeon. One recent, high-quality study showed a 17-fold range in complication rates between weight loss surgery programs!10
On the contrary, Dr. Oliak has collected and applied his own data to create a standardized process for how he performs gastric sleeve and gastric bypass surgeries. His surgical techniques are exact so that his patient outcomes statistics are consistently excellent.

Evaluating which weight loss surgery program and bariatric surgeon is right for you
When you’re evaluating which weight loss surgery program and bariatric surgeon is right for you, you need to know their outcomes statistics for weight loss and surgical complications. However, most surgeons do not share their outcomes data--if they collect it at all. Without knowing the numbers, how can you gauge the quality of the surgeon?
Dr. Oliak not only collects his own outcomes data, he’ll share it with you during your first free, no-obligation consultation. (He also publishes this information on his website.)
Dr. Oliak chooses only the best surgical facilities for his surgeries.
Dr. Oliak partners with only the best bariatric surgery facilities. He only operates at MBSAQIP-accredited bariatric surgery center of excellence (COE) hospitals, and a premier bariatric surgery outpatient surgery center. Our partner facilities put patients--not profits--first. High-quality patient care, service, and outcomes are paramount.
Our Los Angeles County outpatient surgery center partner is not like typical surgery centers. It was developed primarily for bariatric surgery, with top-of-the-line bariatric equipment and 4 private overnight rooms with 24 hour nursing. For select insurance and cash pay patients, we can offer surgery at our partner surgery center with an overnight stay for less cost than at our partner hospitals.
Dr. Oliak is obsessed with providing high-quality patient care.
Ultimately, a patient’s success with weight loss surgery doesn’t depend upon the surgery alone. The other important part of long-lasting weight loss is up to patients and their willingness to establish appropriate eating and exercise habits. In the past you may have found those habits hard to change. This time, it will be different. Because surgery changes your biology, your body will no longer be working against you to make these changes.
Dr. Oliak’s weight loss surgery program emphasizes high-quality patient care:
Our weight loss surgery program includes pre- and post-operative education and follow-up with Dr. Oliak. We also connect patients with support group meetings and online support.
We prioritize frequent follow-up after surgery (for up to 1 year) to get you on track to meet your long-term weight loss goals, and to make sure you achieve your long-term weight loss goals. Because weight loss is so good at the beginning, it’s common for patients to make the mistake of thinking they don’t need to establish good habits right away. But being off track in the beginning can lead to not achieving your long-term weight loss goals.
We want you to be able to maintain your new body weight set point, so we also encourage long-term follow-up after one year as well.
