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, and etc.

My academic background includes a Post-Certificate DNP in Psychiatric Mental Health from the University of Illinois Chicago, a Doctorate of Nurse 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.

I provide compassionate, evidence-based mental health care in a safe, judgment-free space.

I truly believe that no matter how overwhelmed you feel right now, you are capable of healing. Sometimes, the most important part of the journey is simply having a space where you feel seen, heard, and completely accepted without judgment. Since 2018, I’ve been walking alongside individuals as they navigate the complexities of life, and more recently, I’ve dedicated my practice to supporting parents through the highs and lows of the prenatal and postpartum period. Whether you are struggling with depression, anxiety, OCD, or the weight of past trauma, I am here to help you find your way back to yourself.

I am a Licensed Marriage and Family Therapist supporting individuals as they navigate life’s challenges and work toward meaningful, lasting change. My approach is warm, collaborative, and grounded in evidence-based practices. I strive to create a safe space where individuals feel genuinely heard, understood, and supported.
