Code 3 Emergency Physicians was founded in August of 2013 by Board Certified Emergency Medicine Physician, Carrie de Moor, MD, FACEP.

After spending the first part of her career in both Freestanding Emergency Department settings and serving as Medical Director for a Level 1 Trauma Center, Dr. de Moor is using her administrative experience and beliefs in the value of physician ownership/partnership to create a group of like-minded Emergency Physicians to staff Freestanding and Hospital Based Emergency Departments.

After many months of planning, Code 3 Emergency Physicians secured their first Freestanding Emergency Center staffing contract in the summer of 2014.

In early 2015, Code 3 Emergency Physicians secured a staffing agreement with ExcelER Freestanding Emergency Rooms for their operations in North Texas.

May of 2015, Code 3 Emergency Physicians opened The ER at Craig Ranch in McKinney, Texas, the first Code 3 Emergency Physician owned and operated Freestanding Emergency Center. During the same time period, the group partnered with Republic Emergency Physicians to assist in staffing Wilson N. Jones Hospital in Sherman, Texas.

In July of 2015, Code 3 Emergency Physicians developed a statewide quality and peer review organization for Freestanding Emergency Centers and Emergency Department Observation Units.

Currently, Code 3 Emergency Physicians and Code 3 Emergency Partners, LLC have 3 additional Freestanding Emergency Centers under development and construction in North Texas, with plans to expand to Houston and South Texas. Over the past two years, Code 3 Emergency Physicians has grown rapidly from an initial group of two Emergency Physicians to over 75 board certified/board eligible Emergency Medicine Physicians from all over the United States.
