Meet Our Team

At Holly Hill Hospital, we know that it’s our people who make the difference in the lives of our patients. Each of our team members, from mental health technicians and nurses to doctors and therapists, has the devotion and training to serve our patients with dignity and excellence.

The heart of our team shows their passion and dedication to the recovery process both inside and outside the walls of Holly Hill. All of our psychiatrists have shared their knowledge with others as teachers of psychiatry in university medical centers.

In addition to psychiatry, more than half of our medical staff has significant medical care experience, including having worked as emergency care physicians. Collectively, they’ve published over 40 articles in medical journals and have served in Veterans Affairs hospitals and enlisted military treatment settings.

Recovery isn’t easy, but we want to ensure your journey is as smooth as possible. Our team will walk with you and your loved ones every step of the way.
