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.

Hello, I'm Arch Jungers, PMHNP-BC, and I came to psychiatric care more than seven years as a psychiatric charge RN, leading care teams and sitting with patients in their most difficult moments, before becoming a Nurse Practitioner. I truly believe that together, we can solve any mental health problem. When I'm not here, I'm loving on my dogs, playing tennis, or bowling in my weekly league. I am looking forward to meeting you and seeing how I can be of service to you.

I'm Stephanie Patrick-Calvillo, a Board-Certified Psychiatric Mental Health Nurse Practitioner with a genuine passion for helping people navigate their mental health journeys. I've spent over 15 years in healthcare, and what drives me every day is knowing that mental health challenges don't define you—they're just something we work through together.

My background includes treating adults and adolescents across various settings, from crisis care to long-term recovery programs. I've worked with individuals facing serious mental illness, mood and anxiety disorders, ADHD, eating disorders, substance use concerns, and personality disorders. I also have specialized training in geriatric mental health and dementia-related behavioral changes.

What makes my approach unique is my extensive leadership experience overseeing psychiatric services across multiple facilities. This has taught me not just how to prescribe medication, but how to truly understand the whole person—your daily struggles, your support system, and your goals for feeling better. I take time to explore what's worked before, what hasn't, and why, because effective treatment is never one-size-fits-all.

I'm committed to evidence-based care while recognizing that healing happens differently for everyone. Some people benefit most from medication management, others from therapy integration, and many from a combination approach. I stay current with the latest research and treatment modalities, but I never lose sight of the fact that you're the expert on your own experience.

I believe everyone deserves compassionate, judgment-free care. Whether you're seeking help for the first time or you've been struggling to find the right treatment, I'm here to listen, understand your unique situation, and work collaboratively with you to find solutions that fit your life. My goal is to help you feel heard, supported, and hopeful about your path forward.
