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.

I'm Stephanie Patrick-Calvillo, a Board-Certified Psychiatric Mental Health Nurse Practitioner who believes mental health care should be accessible, compassionate, and tailored to each individual. 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 specialize in treating mood disorders, anxiety, psychotic disorders, personality disorders, substance use concerns, and behavioral issues related to dementia. 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.

When you work with me, you're getting someone who genuinely cares, who's seen mental health challenges from many angles, and who believes deeply in your capacity for healing and growth.

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.

Hello! I'm Amanda Long, a board-certified Psychiatric Mental Health Nurse Practitioner dedicated to serving families through compassionate, culturally sensitive mental health care. I earned my Master of Science in Nursing from Walden University and have been practicing as a PMHNP since 2019, with over a decade of nursing experience beginning in 2011. My educational foundation also includes a Bachelor of Arts from the University of Illinois in Springfield, which broadened my understanding of human behavior and community dynamics. My journey in mental health has taken me through diverse settings that have shaped my comprehensive approach to care. I've worked in psychiatric emergency services at a major hospital, 23-hour crisis stabilization units, outpatient clinics, correctional facilities, and forensic mental health centers, including fitness-to-stand-trial evaluations. This varied experience has equipped me to understand mental health from multiple perspectives and meet people wherever they are in their journey, whether they're facing an acute crisis or seeking ongoing support. I specialize in medication management for individuals across the lifespan—from children and adolescents to adults and older adults. My treatment areas include depression, anxiety, ADHD, bipolar disorder, trauma-related conditions, psychotic disorders, and other mental health concerns. I'm experienced in both telehealth and in-person care, making quality psychiatric services accessible and convenient for your lifestyle. What drives me is the belief that everyone deserves competent, caring mental health support that honors their unique background and circumstances. I'm committed to improving the communities I serve, one individual and family at a time, through evidence-based practice combined with genuine human connection. My approach centers on partnership and creating a safe environment for healing. I look forward to supporting you and your family's wellness journey.

Hello, I'm Arch Jungers, PMHNP-BC, and I came to psychiatric care more than seven years as a psychiatric charge RN, leading care teams and sitting with patients in their most difficult moments, before becoming a Nurse Practitioner. I truly believe that together, we can solve any mental health problem. When I'm not here, I'm loving on my dogs, playing tennis, or bowling in my weekly league. I am looking forward to meeting you and seeing how I can be of service to you.
