Express Lab was founded in 2000 by John E. Liljenquist, MD., founder of Rocky Mountain Diabetes Center. Dr. Liljenquist and his fellow physicians are nationally renowned diabetes and endocrinology experts.

Dr. Liljenquist recognized the need for additional clinical laboratory services in the Idaho Falls and surrounding areas and saw an opportunity to fill this need with his own in-house medical laboratory. Express Lab was created as a local independent reference laboratory to help use the extra capacity of the Rocky Mountain Diabetes lab.

Over the past 17 years, Express Lab has grown in size and volume to that of a regional hospital laboratory serving clients all over Eastern and Western Idaho.  Now with seven convenient locations to serve our customers, Express Lab continues to grow and offer excellent local service for patients, physicians and wellness minded corporations.

Express Lab is known for its customer service, friendly staff, exceptional phlebotomists, and fast turn-around times for medical laboratory results.

We are an integral member of a family of medical companies including Rocky Mountain Diabetes Center, Rocky Mountain Clinical Research and Rocky Mountain Pharmacy.
