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.

I'm Stephanie Patrick-Calvillo, a Board-Certified Psychiatric Mental Health Nurse Practitioner with a genuine passion for helping people navigate their mental health journeys. I've spent over 15 years in healthcare, and what drives me every day is knowing that mental health challenges don't define you—they're just something we work through together.

My background includes treating adults and adolescents across various settings, from crisis care to long-term recovery programs. I've worked with individuals facing serious mental illness, mood and anxiety disorders, ADHD, eating disorders, substance use concerns, and personality disorders. I also have specialized training in geriatric mental health and dementia-related behavioral changes.

What makes my approach unique is my extensive leadership experience overseeing psychiatric services across multiple facilities. This has taught me not just how to prescribe medication, but how to truly understand the whole person—your daily struggles, your support system, and your goals for feeling better. I take time to explore what's worked before, what hasn't, and why, because effective treatment is never one-size-fits-all.

I'm committed to evidence-based care while recognizing that healing happens differently for everyone. Some people benefit most from medication management, others from therapy integration, and many from a combination approach. I stay current with the latest research and treatment modalities, but I never lose sight of the fact that you're the expert on your own experience.

I believe everyone deserves compassionate, judgment-free care. Whether you're seeking help for the first time or you've been struggling to find the right treatment, I'm here to listen, understand your unique situation, and work collaboratively with you to find solutions that fit your life. My goal is to help you feel heard, supported, and hopeful about your path forward.

I am Sharon Atwood, a board-certified Psychiatric-Mental Health Nurse Practitioner and Adult Nurse Practitioner with over a decade of dedicated clinical experience. I hold active, unrestricted licenses in Florida, New York, California, and Idaho, and I specialize in serving adults aged 18 and older through both telehealth and outpatient settings.

My educational foundation reflects a lifelong commitment to excellence. I earned my Associate in Science and Diploma in Nursing before completing a Bachelor of Arts in Psychology magna cum laude from Kean University. I then pursued my Master of Science in Nursing from Florida Atlantic University and a Post-Master's Certificate in Psychiatric-Mental Health from the University of Miami, both achieved summa cum laude. I maintain dual board certifications through ANCC and AANP, and I am a proud member of the American Academy of Nurse Practitioners, the American Psychiatric Nurses Association, and the California Association of Nurse Practitioners.

My clinical background spans diverse settings, including adult and geriatric primary care, inpatient psychiatry, crisis intervention, hospital consultation, assisted living environments, and outpatient psychiatric medication management. This breadth of experience equips me to confidently address a wide range of conditions, including depression, anxiety, PTSD, ADHD, bipolar disorder, panic disorder, OCD, schizophrenia, schizoaffective disorder, sleep disturbances, and complex co-occurring presentations. I welcome individuals with treatment-resistant symptoms.

My approach is collaborative, evidence-based, and rooted in genuine partnership. I combine psychiatric medication management with integrative health practices, examining how sleep, nutrition, exercise, stress, and social connection shape your overall wellbeing. I believe that meaningful progress flourishes when expert care is paired with healthy lifestyle.

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 have spent over 40 years teaching, training, and developing mental health programs for individuals from 4 to 84 find hope once again. I am a life-long learner and add at least one certificate a year to ensure clients are given multiple approaches to what they encounter. I am very honest and direct, but also understand the need for pause and reflection. You know the level of your pain and suffering. My job is to meet you where you are and lead you to the place you want to go.
