Additionally, our physicians are board certified in a variety of specialties that permit medical interdisciplinary treatment of our patients, including: neurology, psychiatry, neuropsychiatry, pediatric neuropsychiatry and adult and pediatric physical medicine and rehabilitation.

Exclusively caring for our neurospecialty patients full-time, Nexus Physician Services represents a group of doctors who are dedicated to furthering our neurocontinuum of care and supporting our patients and their families. Additionally, these physicians educate our staff and community through continuing education presentations, grand rounds, and other educational opportunities.

Physicians associated with this elite group are aligned to Nexus’ standards and treatment philosophy. All doctors who are a part of Nexus Physician Services are under our supervision and clinically report to Dr. John Cassidy, Chief Medical Officer.
