Hi, I’m Christina! I’m a double board-certified Family Nurse Practitioner and Psychiatric Mental Health Nurse Practitioner with over 12 years of experience in healthcare. I earned my bachelor’s degree from UCLA, master’s from Cal State LA, and post-graduate certification from National University.
Over the years, I’ve had the opportunity to work in family practice, urgent care, and emergency settings, which has given me a broad understanding of how physical and mental health are connected.
I specialize in supporting individuals who are dealing with depression, anxiety, PTSD, insomnia, mood disorders, and other mental health concerns.
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.
Trained in a State Hospital in a borough in New York City
Welcome! I’m Sarah Stewart, and I specialize in medication management for adults dealing with depression, anxiety, ADHD, bipolar disorder, and other mental health conditions. Together, we’ll explore your goals, strengths, and patterns to create a treatment plan that feels personal and empowering. My approach blends evidence-based care with compassion and collaboration—helping you find both immediate relief and lasting stability. You deserve care that meets you where you are and helps you move toward a more grounded, confident version of yourself.
I provide a safe, supportive, and nonjudgmental space where we work together to understand your unique needs and goals.
I believe healing happens when patients feel seen, heard, and empowered. My role is to walk alongside you, offering tools, education, and medication management tailored to your individual journey.
I completed my training as a PMHNP in California and have experience in both emergency and outpatient mental health settings.
If you’re ready to take the next step in your mental health journey, I look forward to working together to build a plan that supports your well-being.
As a Psychiatric Mental Health Nurse Practitioner, I aim to create a space where you feel heard, respected, and understood. I believe mental health care should be collaborative, practical, and tailored to your unique needs. My approach combines evidence-based treatment with real-life understanding whether that includes therapy, lifestyle changes, or medication management when appropriate. I value honesty, cultural awareness, and meeting you where you are. My goal is to help you feel more stable, confident, and in control of your mental health not just during appointments, but in your everyday life.
I’m passionate about helping those who need help mentally and emotionally
Nice to meet you! I'm a board-certified psychiatric nurse practitioner with TapRoot Healing: a mental health and addiction medicine clinic in Newport Beach founded by Dr. Atul Grover. We met while working at Hoag, where we bonded over a shared approach to patient care, one rooted in compassion and humility. I am deeply dedicated to this field and always expanding my knowledge to best serve my patients. I would be honored to work with you!
