Substance use disorder (SUD) provider Crossroads Treatment Centers has named Dr. James Stephen its next chief medical officer.

Stephen comes to Crossroads after working in the home health care sector. Most recently, he served as a regional medical officer at home health provider Landmark Health, which is now under UnitedHealth Group’s (NYSE: UNH) Optum umbrella. His resume also includes tenure at Lovejoy-St Vincent Health Care Center of Catholic Health System, where he served as the medical director.

“I am eager to help Crossroads deliver care to underserved populations,” Stephen said in a statement. “I have many years of experience treating opioid and polysubstance-dependent patients, and a deep commitment to serving this patient population. I hope to serve them, and Crossroads, by leading with deep commitment to physical, emotional and mental well-being.”

Founded in 2005, South Carolina-headquartered Crossroads provides outpatient substance use disorder treatment. It operates more than 110 facilities in nine states. The company uses medication-assisted treatment (MAT), in-person visits, telehealth visits, lab services and intensive care coordination services.

In 2022, private equity firms Revelstoke Capital Partners and Canada-based Caisse de dépôt et placement du Québec (CDPQ) completed a recapitalization of Crossroads. Crossroads said the funding from the recapitalization would go towards expansion and acquisitions.

This new appointment comes at a time when rates of SUD have increased and cases are more complex. A new study from addiction provider Ideal Option reports that as many as 61% of patients with SUD present with polysubstance use.

Several C-suite shake-ups have occurred in the SUD treatment space over the last few years.

For example, addiction provider Caron Treatment Centers announced its CEO, Bradley Sorte’s, plans to step down earlier this year. Additionally, at the end of last year, in-home SUD provider Aware Recovery named a new COO, Discovery Behavioral Health hired a new president for its substance use disorder division, and digital SUD provider Eleanor tapped a new CFO and chief of staff.
