Meet Orange County Bariatric Surgeon David Oliak, MD

Dr. Oliak made two life altering decisions at a young age while growing up in Kenosha, Wisconsin. He decided he wanted to live somewhere warm, and that he wanted to be a doctor.

He moved south to Evanston, Illinois to attend college at Northwestern University, (B.S. degree chemical engineering), and further south to St. Louis, Missouri, to attend medical school at top-ranked Washington University School of Medicine.

After medical school he moved to the warm weather of Los Angeles (finally!) for a 6 year general surgery residency at Harbor-UCLA Medical Center.

Dr. Oliak decided during his surgery residency that he wanted to specialize in laparoscopic weight loss surgery. This outweighed his desire for warm weather, so after his residency he moved to Manhattan for a one-year laparoscopic bariatric surgery fellowship (one of the first in the country) at Hackensack University Medical Center in New Jersey.

After completing his fellowship in 2002, Dr. Oliak moved back to the warm weather of Southern California with his future wife (whom he met in NYC) to start his practice as a laparoscopic bariatric surgeon in Orange County and Los Angeles.

Dr. Oliak’s practice philosophy has always been to prioritize patients first. What this means to him is achieving the best possible outcomes for his patients. This is the #1 thing he would want as a patient, so this is the #1 thing he prioritizes as a surgeon.

In Dr. Oliak’s experience, quality of surgery, thorough and comprehensive patient education, frequent follow-up after surgery, and ongoing support are the key elements necessary for achieving great outcomes. These are the key elements of his bariatric surgery practice.
