Addiction therapists & psychiatrists in Arcadia, CA

My path into psychiatry is both professional and personal. I moved to the U.S. alone at 17 while navigating complex PTSD and periods of misdiagnosis, which shaped how I understand mental health today. I began with a bachelor’s degree in psychology at Nankai University, then trained as a nurse and nurse practitioner at Charles R. Drew University and Purdue University.

Over the past 7 years, I’ve worked across medical and mental health settings, developing an approach that balances clinical precision with individualized care. I specialize in anxiety, depression, bipolar disorder, and complex PTSD, particularly for individuals who feel stuck or haven’t found relief in traditional treatment.

I’m licensed in California, Virginia, New York, Washington, and Oregon, and provide care via telehealth.

For the past year, I've worked with adults facing serious mental health challenges at one of Los Angeles's largest public health systems, and what I've learned is that lasting change comes from relationships built on trust. Now I'm bringing that experience into private practice, where I can focus on what matters most: your individual progress. I work with people navigating anxiety, depression, and PTSD, and I offer flexible evening and weekend availability via telehealth throughout California. As a PMHNP, I'm here to support your whole mental health journey.

I work with teens, young adults, and families navigating ADHD, anxiety, depression, substance use, identity exploration, family conflict, relationship challenges, life transitions, and emotional overwhelm. Whether you're feeling stuck, disconnected, overwhelmed, or uncertain about what comes next, therapy can provide a space to better understand yourself and move toward meaningful change.

My approach is warm, collaborative, and nonjudgmental. I believe therapy works best when clients feel genuinely understood, supported, and accepted for who they are. Together, we build on strengths, develop practical coping skills, and explore the patterns that may be getting in the way of living a more fulfilling life.

I strive to create a safe and supportive environment where clients can be honest, reflective, and fully themselves without fear of judgment. My goal is not only to help clients navigate current challenges but also to foster greater resilience, self-awareness, confidence, and connection.

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.
