The Forefront of Addiction Treatment Medical Directorship

Physician-led medical oversight and management under the leadership of Dr. Jayson A. Hymes, M.D., M.P.H.

REGENT is a physician-owned medical directorship company based in California. The company exists to provide structured medical leadership, governance, and oversight for addiction treatment programs operating within regulated professional environments.

REGENT does not operate as a treatment facility and does not provide direct patient care. Its role is to ensure that medical authority within treatment programs is clearly defined, ethically grounded, and exercised with accountability.

Medical leadership at REGENT is exercised through the clinical authority of Dr. Jayson A. Hymes, supported by an institutional structure designed to uphold regulatory responsibility, professional standards, and long-term medical stewardship.
