Redefining Physician-Led Directorship for California Addiction Treatment Centers

Regent provides a level of physician-led directorship that is rare in California. Our services cater specifically to addiction treatment centers and clinics. Services are provided exclusively by Harvard-trained California addiction medical director, Dr. Jayson A. Hymes, MD, MPH, DFASAM, DFACPM, QME and his team.

Dr. Hymes leads with hands-on oversight and careful quality assurance.

A Boutique, Physician‑Led Approach

Regent exists for facility owners who want clinical decisions guided by a physician with top-tier expertise, rather than a volume-based medical director company.

Unlike rotating‑physician models or volume‑based firms, Regent is built around a single point of leadership.

Our clients rely on Dr. Hymes for:

●      Established clinical protocols

●      NP/mid-level oversight

●      Ongoing clinical accountability

●      Continuous review of patient progress

●      Ongoing evaluation of the clinical team

●      Deep roots in the local medical community for rapid specialty referrals

●      EHR-ready protocols, forms and templates

●      Extensive experience with peer-to-peer physician support

●      Extensive expertise with medication-assisted treatment (MAT)

What We ARE and ARE NOT

We are

a physician-led medical directorship, not a staffing agency. We provide an intensive and well-defined medical oversight framework designed exclusively for your clinical model. 

Count on us for continuous review of patient progress, ongoing team evaluation and consistent protocol updates.

We are not

A behavioral treatment provider. We do not manage daily operations, case management, or counseling.
