Helping people reclaim their mental health and quality of life is not just my profession — it is my purpose. I am Christina Stelly, a Board-Certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) based in Martinez, California, with a deep commitment to compassionate, evidence-based psychiatric care. My path to this work has been shaped by years of experience across diverse, high-acuity clinical settings, and I bring both clinical expertise and genuine care to every patient I serve.

My educational foundation 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 — all built upon over a decade of hands-on clinical nursing experience.

I provide comprehensive psychiatric evaluations, medication management, and crisis intervention for veterans navigating conditions including schizophrenia, bipolar disorder, PTSD, and substance use disorders. Prior to this role, I completed an advanced NP residency focused on forensic psychiatry and crisis stabilization, and served as Patient Care Director overseeing high-risk maternal mental health at the University of Illinois Chicago.

I specialize in caring for diverse and underserved populations, including veterans, individuals with severe mental illness, co-occurring disorders, and those in acute psychiatric crisis. My perinatal psychiatry background also provides a unique perspective for supporting individuals through some of life's most vulnerable transitions.

Beyond direct patient care, I am an active mental health policy advocate, contributing to state advisory councils and national nursing organizations. I believe every person deserves dignified, individualized care — and if you are ready to take the next step, I warmly welcome the opportunity to connect and support you.

I’m a Board-Certified Psychiatric Mental Health Nurse Practitioner who believes mental health care should feel human—not rushed or impersonal.

I provide a non-judgmental space where you can speak openly and feel understood. My approach integrates thoughtful medication management with psychotherapy when appropriate, always tailored to your individual needs.

Diagnosis can be an important part of understanding your experience, but it’s only one piece of the picture. I look at your mental, physical, and emotional well-being, as well as the life experiences that shape what you’re going through.

I offer collaborative, grounded care to help you move toward a more balanced, integrative, and holistic sense of well-being.

Guaranteed intake appointment available within a week, usually a few days! A provider you can reach directly, by text. Personal responses to all messages within 24 - 48 hours, always. Evening and weekend hours available.

Thanks for reading this. I am a board-certified psychiatric nurse practitioner with over 14 years of experience. I work with clients ages 6 to 86 struggling with depression, anxiety, ADHD, borderline personality disorder, substance abuse and other issues. I help clients to find stability and reduce suffering.

Depression and anxiety can be logical responses to difficult life events. Many adults who experienced losses and traumas in childhood have never processed these events and continue to suffer their impacts.

(Please note that I am no longer taking on new therapy clients, I am only accepting new clients for medication management at this time.)

Hi there, I'm a board-certified Psychiatric Mental Health Nurse Practitioner whose practice is rooted in one foundational belief: every person deserves compassionate, individualized mental health care — regardless of background, circumstance, or the barriers and challenges they've faced along the way.

I focus on the treatment of depression, anxiety, and life's traumas, with a particular dedication to individuals from underserved and marginalized communities who have historically faced systemic barriers to quality mental health care.

All care is grounded in evidence-based practice, blending the most current clinical research with individualized judgment and patient-centered values. As a lifelong learner, I actively pursue continuing education and emerging best practices in psychiatric care — because excellence in medicine requires ongoing growth, humility, and a willingness to be taught by both science and the patients who make this work meaningful.

I welcome patients of all backgrounds and identities, and I am honored to walk alongside each person on their journey toward healing, wholeness, and hope.

I'm invested in helping you find value and joy in your life!

For over the past decade in this field, I have assisted clients at all stages of life. I prefer to show up with humility, humor, and genuine humanity.

My goal is to help you overcome the challenges you are facing in a safe and comfortable environment to help you improve your quality of life. My passion is helping those with substance use disorders, including alcohol and opioid use disorder, safely detox from the substances and work towards a meaningful and long-lasting recovery. With a decade of experience serving a wide range of patients I am a dual-certified family nurse practitioner and psychiatric mental health nurse practitioner.

I am a dual board-certified Nurse Practitioner specializing in both Family Practice and Psychiatric Mental Health. With a foundation in whole-person, evidence-based care, I integrate medical management with psychotherapy and lifestyle interventions to support mental and physical wellness.

My background spans outpatient psychiatry, primary care, home health, and assisted living settings, allowing me to understand the unique needs of patients across all stages of life. I have extensive experience treating mood and anxiety disorders, trauma-related conditions, and chronic medical comorbidities that impact emotional well-being.

I believe in creating a collaborative, compassionate, and culturally sensitive environment where patients feel heard and empowered to take an active role in their care. My approach focuses on building balance—supporting both the mind and body—through medication management, therapy, and integrative care strategies.
