Alliance was formed in 1996 in response to competitive regional managed care trends that threatened physician practice revenues and market positions. The founders were aware of medical group needs to upgrade management and succeed in the evolving business of healthcare.

In more recent times, Alliance has broadened its scope through a continuing quest for a full continuum of healthcare management and other services. It has developed a variety of system alliances in various specialties to become Alliance Healthcare Systems, Inc. (AHS). These alliances include HCA Hospitals, Triumph HealthCare, HealthScan, and the Technology Risk Management Group.

With a cutting-edge management services organization (MSO), the establishment of a foundation (The Institute for Radiological Research) and expansion into the teleradiology market, AHS provides the model for futuristic healthcare services. In a continuing quest for expanding alliances, AHS provides administrative services and management consulting to achieve aggressive market growth, service diversity, effective operations, sound financial performance, full patient satisfaction, and high quality assurance for all of it's members.
