Mark Davis
Mark Davis began his social work career in 1996 working as a Rehabilitative Specialist at an area psychiatric community mental health center where he provided supportive counseling and group rehab to individuals entering an in-patient setting. After receiving his master’s degree in social work from the University of Oklahoma in 2005, he continued his unyielding promotion of hope and recovery for people impacted by mental illness, homelessness, trauma, debilitating poverty and those facing challenges as a result of involvement with the criminal justice system. Ultimately, his drive to assist at-risk populations along with a more global goal of improving the social service system(s) across the community led to his current position as Chief Programs Officer for Mental Health Association Oklahoma.

Gregory Shinn
