Hello, my name is Alexander Valenzuela PMHNP. I specialize in psychiatric medication management and cognitive behavioral talk therapy. If you're struggling with your mental health and realize you want help, you don't have to do it alone. I am looking forward to starting the journey with you to help achieve your best self.
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.
Welcome, I'm glad you're here.
I’m Bechael S. Harris, MSN, APRN, PMHNP-BC, a board-certified psychiatric mental health nurse practitioner with over 27 years of nursing experience. I provide care for adults and older adults navigating challenges such as depression, anxiety, dementia, Alzheimer’s disease, and other mental health concerns. My practice blends compassion, evidence-based treatment, and a commitment to helping each person feel heard, valued, and supported.
As a Board-Certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC), I provide psychiatric evaluations, diagnosis, and treatment for a wide range of mental health concerns. As a military spouse, I also understand the unique challenges that military members and their families often face.
Whether you’re seeking support for the first time or looking for a provider who truly listens, my goal is to help you feel better, function more effectively, and move forward with confidence.











Headway makes it easy to find support for your mental health — from finding the right provider, to understanding costs, to scheduling with ease.
Finding the right psychiatrist in Whittier starts with understanding what kind of care you need. Psychiatrists are medical doctors who can diagnose mental health conditions, prescribe medication, and in some cases provide therapy. If you're looking for help with anxiety, depression, ADHD, bipolar disorder, or medication management, a psychiatrist may be the right fit. Psychiatric nurse practitioners can also prescribe and manage medication and are another option available through Headway.
With many providers practicing across Whittier and the surrounding LA County area, narrowing your search can take time. Consider what matters most to you — whether that's a provider who specializes in a specific condition, offers virtual appointments, or is located near your neighborhood. Reading a provider's bio can help you understand their approach and decide if they're a good match before you book.
Psychiatry sessions in Whittier can be expensive without insurance. Using your in-network benefits is one of the most reliable ways to lower your out-of-pocket costs. On Headway, you can enter your insurance details to see estimated session costs upfront, and many patients pay as low as $0 per session. Nationally, Headway partners with over 100 insurance plans, making it easier to find a psychiatrist who is both the right clinical fit and covered by your plan.
