Clinical Leadership

Dr. Mark Ettinger is a board-certified anesthesiologist with 20 years of clinical practice and physician leadership experience in Dallas–Fort Worth. He founded Meridian Anesthesia in 2025 and serves as its President, leading clinical operations, recruiting, and quality across Meridian’s hospitals, which include two trauma centers.

From 2011 to 2025, Dr. Ettinger practiced with a physician-owned, multi-facility anesthesia group in Dallas, where he was a managing partner. At Medical City Arlington, a 500-bed Level II trauma center, he served as Chair and Medical Director of the Department of Anesthesiology, Director of the Preoperative Assessment Clinic, and Chair of the Hospital Ethics Committee, leading a department of more than 50 anesthesiologists, CRNAs, and support staff. In 2025 he led the hospital’s transition from a physician-only anesthesia group to a care-team model under Meridian and NPH.

Dr. Ettinger also designed and built Equinox, the software platform that runs Meridian’s practice — scheduling, credentialing, provider compensation, billing reconciliation, and analytics.

He earned his medical degree from LSU Health Sciences Center in New Orleans, where he graduated as valedictorian and was elected to Alpha Omega Alpha. He did a general surgery internship and three years of neurosurgery residency at UT Southwestern, then completed his anesthesiology residency at The Johns Hopkins Hospital in 2011. He is a Diplomate of the American Board of Anesthesiology. He also spent several years as the anesthesia director on a Faith in Practice team doing medical mission work in Guatemala.

Dr. Ettinger and his wife, Gena, have three children, Eli, Gavin, and Savannah. In his free time, he loves to play guitar, work out, travel to LSU football games, and spend time camping and hunting with his family and their German Shorthaired Pointer, Slick. He is also a commercial pilot and flight instructor.
