Hello and Welcome

With 30 years of experience as a licensed marriage, family therapist, my journey began at Sacramento California, where I first received my license and found my calling serving families within the community.

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’m Antionette Sob, a Board-Certified Psychiatric Mental Health Nurse Practitioner dedicated to empowering individuals to live fuller, more balanced lives. With over a decade of nursing experience and advanced training in mental health, I aim to provide safe, supportive, and compassionate care. I believe that everyone can heal and grow — sometimes we need the right tools and guidance.

I’m here to make this journey feel gentle, welcoming, and human. I keep things clear and simple so you can focus on what matters, not the overwhelm. My style is warm, encouraging, and a little poetic—because softness helps us breathe. Let’s take this step together, one calm moment at a time.

Many people come to me feeling overwhelmed, anxious, burnt out, or simply “not like themselves.” Whether the root is mental health, hormones, or a mix of both, my goal is to help you understand what’s happening in your body and mind — and create a plan that actually helps you feel better.

I am a Family Nurse Practitioner with over 13 years of experience treating complex chronic conditions, acute medical issues, and a wide range of mental health concerns. My background in the emergency room strengthened my ability to stay calm, think clearly, and support patients through some of their most difficult moments.

I am double board‐certified as an FNP‐BC and PMHNP‐BC, which allows me to integrate medical and psychiatric expertise. This means I look at the full picture — hormones, sleep, stress, mood, lifestyle, and physical health — to understand what’s driving your symptoms.

My approach is compassionate, practical, and evidence‐based. I take time to listen, explain things clearly, and work with you to create a treatment plan that fits your life. You deserve care that feels supportive, personalized, and focused on long‐term wellness.

If you’re ready to feel more balanced, focused, and in control again, I’m here to help you get there.

We'll apply, or challenge, your believe system, to make positive changes.
