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.

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 currently a licensed psychologist in California, having previously worked as a psychotherapist under supervision for over 14 years. As an independent practitioner, I am accepting new clients, both in person and by remote means.
I seem to work especially well with younger and middle-aged people who are creatively inclined and having difficulty with self-realization and/or interpersonal relationships, from important relationships to everyday interactions with others. In the past, I have worked in community-based and private addiction recovery settings across a wide demographic. I specialize in trauma informed treatment that includes PTSD, depression, anxiety and phobias.

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'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.

Hi, I’m a psychiatric nurse practitioner who believes everyone deserves to feel heard, supported, and treated with kindness. I create a warm, welcoming, and judgment-free space where you can feel comfortable being yourself. I work with clients experiencing anxiety, depression, stress, mood changes, and other mental health concerns. Along with medication management, I also use supportive therapy techniques, including CBT and motivational interviewing, to help clients build healthy coping skills and feel more confident in their daily lives.
For the past six years, I have been providing therapy to individuals as part of my clinical training as a clinical psychologist. I have had the privilege of supporting people through challenges related to substance use, codependency, anxiety, depression, trauma, and struggles with self-confidence and self-esteem. My goal is to create a warm, collaborative, and nonjudgmental space where clients feel safe, supported, and empowered to grow, heal, and reconnect with themselves.

As a PMHNP-BC who specializes in autism, complex cases, OCD, personality disorders, PTSD/trauma, schizophrenia/psychosis disorders, and substance use, I've built my practice around understanding that every person's mental health journey is unique—especially when multiple conditions interact or when traditional approaches haven't worked.
I also provide comprehensive treatment for depression, anxiety, panic disorders, mood disorders, and bipolar disorder, always with an understanding that these conditions often overlap and influence each other in complex ways. What I want you to know is this: your experiences are valid, your struggles make sense in the context of your life, and there's no such thing as being "too much" for treatment.
Whether you're masking autistic traits, battling compulsive behaviors, managing intense emotions, processing trauma, questioning reality, or struggling with substances, I meet you exactly where you are without trying to force you into a predetermined mold. My approach combines evidence-based treatments with deep respect for your individual needs and experiences.
You deserve a provider who doesn't see complexity as a problem to solve, but as a roadmap to understanding how to best support your unique path to wellness.
