About Us

Gastroenterology Associates was founded in 1986 by Dr. Frank Nemec. From day one, Dr. Nemec focused on procedural safety. Because of that steadfast commitment, Gastroenterology Associates has established a reputation as Southern Nevada’s most reliable, consistent gastroenterology practice. We voluntarily seek and exceed stringent national standards for medical quality and safety to ensure the most technologically advanced and reliable diagnostics and treatment plans. We are honored to be referred to patients by many of Las Vegas’ premier primary care physicians and work closely with these doctors to manage effective digestive health treatment.

Today, Gastroenterology Associates is home to four of Southern Nevada’s most respected gastroenterologists. Dr. Gregory Kwok, Dr. Donald Kwok and Dr. Brent Burnette have all joined Dr. Nemec as board certified physicians specializing in digestive health.
