Discovery Behavioral Health, a prominent provider of mental health, substance use disorder, and eating disorder treatment services, has made one of the most significant behavioral health leadership appointments by appointing Dr. Matthew Ruble as its new chief medical officer (CMO). Headquartered in Los Alamitos, California, Discovery Behavioral Health operates 130 treatment centers across 13 states, positioning itself as a key player in the behavioral health care landscape.
Dr. Ruble brings a rich and varied background in psychiatry, medical education, and healthcare leadership, which will be instrumental in supporting Discovery Behavioral Health’s mission to deliver superior patient outcomes. He reports directly to John Peloquin, the company’s CEO and President, and will play a critical role in shaping the clinical direction of the organization.
Before joining Discovery Behavioral Health, Dr. Ruble spent seven years at Humana Inc., a senior-focused insurance and healthcare company. His tenure included five years as a medical director and one year as lead medical director, managing complex care programs tailored to vulnerable populations. Prior to that, Dr. Ruble worked for 14 years at Cambridge Health Alliance, a Harvard Medical School teaching hospital affiliate, where he served as associate training director for the residency program. This blend of clinical practice, academic involvement, and executive experience equips him uniquely for his role as CMO.
John Peloquin highlighted Dr. Ruble’s qualifications and experience as foundational to Discovery Behavioral Health’s goals. “Dr. Ruble’s experience as a practicing psychiatrist, a teacher, and a healthcare provider executive is foundational for meeting our goal of providing the best outcomes for the treatment of eating, mental health, and substance use disorders,” Peloquin said in a recent news release.
Dr. Ruble’s medical education credentials are notable. He earned his medical degree from the University of Iowa College of Medicine, followed by an internship and residency in adult psychiatry at Harvard Medical School’s Cambridge Health Alliance. He also completed a chief residency specializing in advanced psychopharmacology and pursued a fellowship in medical education at Harvard Medical School, underscoring his commitment to academic excellence and clinical innovation.
A key focus for Dr. Ruble will be enhancing the therapeutic alliance between patients and providers—a critical element for effective behavioral health treatment. The ability to foster trust and collaboration directly impacts recovery rates and overall patient satisfaction. With this goal in mind, Discovery Behavioral Health is rolling out an integrated outpatient services division designed to provide more seamless, coordinated care.
