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.

I'm Saby Kirpal, a Psychiatric Mental Health Nurse Practitioner dedicated to providing comprehensive mental health care. I hold Master's degrees from Chamberlain University and Walden University, graduating with Presidential Honors, reflecting my commitment to clinical excellence. My diverse professional background spans inpatient psychiatric hospitals, residential treatment centers, and outpatient clinics, giving me insight into mental health treatment at every level of care. I specialize in treating depression, anxiety, autism spectrum disorders, eating disorders, and substance use disorders across age groups. My experience includes working with children as young as eight through adults in crisis stabilization, residential treatment, and ongoing medication management.

What makes my practice unique is the integration of my nursing background with psychiatric expertise. I understand how physical health, medications, lifestyle factors, and mental health interconnect. Being trilingual in English, Hindi, and Punjabi, with conversational Spanish, allows me to serve diverse communities and appreciate how culture shapes mental health experiences.

I've worked from UCSF Health to community clinics, teaching me that excellent care isn't about the setting—it's about the relationship. Whether you're seeking help for the first time, between providers, or managing ongoing conditions, I'm here to partner with you. My approach centers on listening first, explaining clearly, and making decisions together. Mental health treatment should never feel like something done to you, but rather something we navigate together. I'm committed to creating a space where you feel respected, understood, and genuinely supported.
