Orange County Weight Loss Surgery

Weight loss surgery is a big decision. Surgery can greatly improve your life, but you have to be prepared to establish new eating habits after surgery. You also have to choose your surgeon carefully – outcomes (weight loss, complications) are variable between different surgeons. Your choice of surgeon is an important determinant of your ultimate outcome.*

Dr. Oliak’s biggest strength is his long record (>2500 operations since 2002) of excellent, industry-leading patient outcomes. His weight loss outcomes significantly surpass the industry averages, and his complication rates are significantly lower than the industry averages.* There is nothing more important than this. He has achieved this by always working hard to provide his patients with the highest quality surgery and patient care possible.
