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 am passionate about helping women as they navigate the complex intersection of mental health and hormonal well-being. Many of my clients come to me during pivotal life stages—pregnancy, postpartum, menopause—or while managing conditions like polycystic ovary syndrome (PCOS), premenstrual dysmorphic disorder (PMDD), or other endocrine imbalances. These challenges can bring emotional struggles such as anxiety, depression, or mood swings, often leaving women feeling disconnected and overwhelmed.

As a Nurse Practitioner, I believe healthcare should be a partnership, not a prescription. My approach combines advanced clinical skills with a deep commitment to patient advocacy, ensuring every individual has the tools and confidence to take charge of their health. I specialize in creating personalized treatment plans that honor the whole person — mind, body, and spirit. Whether I’m diagnosing, prescribing, or simply listening, my mission is to make every patient feel seen, heard, and cared for. I strive to turn sessions into moments of trust, learning, and hope."

I am board certified in Family Practice as well as Psychiatry and have been in practice for 25 year. I work with mental health issues such as depression, anxiety, sleep disorders, bipolar disorder, as well as address physical symptoms or issues that may affect mental health. I hold a Doctorate degree in education and Master Degrees in Advance Practice Nursing and education.

I am a triple board-certified nurse practitioner in psychiatry, family, and women's health, so have experience caring for a diverse client population. I've worked several years in each specialty and settled in psychiatry, where my passion lies. I specialize in the medication management of depression, anxiety, OCD, PTSD, insomnia, bipolar disorder, and more. Because of my training in women's health, I am uniquely qualified in the psychiatric care of women during pregnancy and postpartum.
