Hi! I'm Christina Stelly, DNP, APRN, PMHNP-BC — a board-certified Psychiatric Mental Health Nurse Practitioner based in Martinez, CA. With over 15 years of clinical experience across inpatient psychiatry, maternal health, and advanced practice, I am deeply committed to delivering compassionate, evidence-based mental health care to every person I serve.

I specialize in treating schizophrenia, bipolar disorder, PTSD, depression, anxiety, etc.

My academic background includes a Post-Certificate DNP in Psychiatric Mental Health from the University of Illinois Chicago, a Doctorate of Nursing Practice from Texas Tech University, and a Master of Science in Nursing from Touro University. I also completed an intensive NP residency focused on advanced psychiatric care, crisis stabilization, and forensic psychiatry, which further strengthened my clinical expertise.

Earlier in my career, I specialized in maternal mental health, serving as a Patient Care Director for high-risk obstetric populations and contributing to perinatal mental health policy at the state and national levels. This background gives me a uniquely broad, whole-person perspective on psychiatric care across the lifespan.

My approach is grounded in trauma-informed, individualized care. I take time to fully understand your history, concerns, and goals before collaboratively building a treatment plan tailored to you. I have also served on health policy committees and presented at national nursing conferences, reflecting my commitment to psychiatric care.

Stuck? In pain? Contemplating a life change, or just had one thrust upon you? Let's explore your options and make things easier.

I have 20+ years of experience helping demoralized adults back to high functionality. I specialize in helping develop motivational skills in those are dealing with depression, anxiety and adjustment issues (including relational and gender identity issues).

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.
