I'm Stephanie Patrick-Calvillo, a Board-Certified Psychiatric Mental Health Nurse Practitioner who believes mental health care should be accessible, compassionate, and tailored to each individual. Over the past 15+ years, I've worked with diverse populations—from adolescents facing their first mental health crisis to adults navigating complex psychiatric conditions, and seniors experiencing cognitive and emotional challenges.

My practice is grounded in the belief that effective treatment goes beyond symptom management. I take time to understand your unique story, your strengths, and the factors that shape your mental health. Whether you're dealing with a new diagnosis or have been managing symptoms for years, I meet you where you are with respect and without judgment.

I specialize in treating mood disorders, anxiety, psychotic disorders, personality disorders, substance use concerns, and behavioral issues related to dementia. I've completed advanced certification training because I'm committed to staying current with evidence-based treatments—ensuring you receive care that reflects the latest research.

Beyond clinical work, I'm passionate about mentoring the next generation of healthcare providers. I've mentored nursing and nurse practitioner students from multiple universities, which keeps me grounded and reminds me why this work matters.

When you work with me, you're getting someone who genuinely cares, who's seen mental health challenges from many angles, and who believes deeply in your capacity for healing and growth.
