Robert Cortez, MSN, PMHNP-BC, is a board-certified Psychiatric Mental Health Nurse Practitioner specializing in psychiatric evaluation, diagnosis, and medication management for adults.

At AMHW, our mission is simple: to help you quiet the internal noise, transform adversity into endurance, and ascend to your absolute peak potential.

Ascend Mental Health and Wellness has a singular vision: to bridge the gap to accessible, high-quality psychiatric care for busy students, professionals, and Inland Empire commuters who simply don't have time for traditional medical appointments.

With over a decade of clinical experience—spanning roles from frontline healthcare to University Professor and advanced practice provider—I recognize that standard psychiatric care often falls short. Too frequently, the system treats the symptom rather than the individual. My practice is dedicated to dismantling that fragmented approach and replacing it with strategic, long-term healing.

I believe that resilience is not an accident; it is a discipline we cultivate. Whether you are managing the demands of a high-pressure career or navigating complex academic environments, mental wellness requires more than the standard, expedited ‘med check.’ It requires a clinical partner who understands the rigorous demands of your lifestyle.

Today, I serve the Inland Empire and San Gabriel Valley with a curated, in-person mental health experience at our Montclair clinic, while extending secure telehealth across Los Angeles and Orange County.

I consult and collaborate with Dr. Dennis B. Alters, psychiatrist and psychotherapist, and expert in cognition and child psychiatry, on complex cases.
