Orange County Weight Loss Surgery

Weight loss surgery is a big decision. It 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 highly variable between different surgeons. Your choice of surgeon is an important determinant of your likely outcome.*

Dr. Oliak’s biggest strength is his long record (>2500 operations since 2002) of excellent, industry-leading patient outcomes. There is nothing more important than this. The way he has achieved this is by always working hard to provide his patients with the highest quality surgery and patient care possible.*
