History & Leadership


Pecan Valley Centers for Behavioral and Developmental HealthCare was legally established in 1976 by the Commissioners Courts of Erath, Hood, Palo Pinto, Parker and Somervell Counties as a Community Center in accordance with House Bill 3. Johnson County joined the Pecan Valley Centers in June 2006.


Pecan Valley Centers is authorized by the Department of State Health Services (DSHS) to be the Mental Health Authority for the Region and authorized by the Department of Aging and Disabilities (DADS) to be the Intellectual and Developmental Disabilities (IDD) Authority for the Region.

Pecan Valley Centers is governed by an eleven member Board of Trustees, appointed by the County Commissioners of the six counties. The Board in turn hires an Executive Director to set procedure, carry out the policies of the Board, and manage the center.

Pecan Valley Centers was established through the hard work of Theresa Mulloy, Ed.D. Dr. Mulloy was appointed the center’s first Executive Director, and honorably served the community from 1976 until her retirement in August 2006. The Pecan Valley Board of Trustees appointed Coke Beatty to succeed Dr. Mulloy’s 30 years of service in September 2006. Mr. Beatty had served the center in other capacities since 1992.
