Bipolar disorder therapists & psychiatrists in Valencia, CA

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.

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.

I am a clinical psychologist working in San Diego, with over 20 years of experience. I earned a BA in Psychology from University of California Santa Barbara, and a Ph.D. in Clinical Psychology from Alliant International University (formerly California School of Professional Psychology). I completed a postdoctoral fellowship in substance use disorders at the San Diego Veteran's Affairs Healthcare System. I have expertise in working with depression, anxiety, mood disorders, substance use problems, relationship issues, and assertiveness. I also conduct psychological testing for questions around ADHD, Autism, mood disorders, giftedness, learning problems, and personality issues, among others. I believe psychotherapy is a collaborative process to help clients understand themselves better, achieve goals, and become one's best self.

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.
