Addiction therapists & psychiatrists in Whittier, CA

One of my joys in life is making a positive difference in my client's lives. Maybe you’ve tried everything; talking to friends/family, reading self-help books, ignoring the problem hoping it will go away, or just accepting how things are and yet you are feeling unhappy and stuck. I believe there is hope for you, a life filled with love, fulfillment and fun. I've had a variety of life experiences (good, not so good) that's given me wisdom and insights about people/life. I work with couples, women/men issues, trauma, depression, anxiety, ADHD. I'll travel with you on your journey of healing/growth with understanding and compassion.

Trauma-Informed. I specialize in treating adults with unresolved childhood traumas / C-PTSD. I deeply understand how early life experiences shape present-day struggles—I specialize in helping people heal from those roots, not just manage surface-level symptoms.

I am trained in powerful, evidence-based and experiential modalities like EMDR, IFS-informed parts work, Emotionally Focused Therapy, the Safe and Sound Protocol, and Ketamine-Assisted Psychotherapy. Not one-size-fits-all—I tailor treatment to each individual’s nervous system, attachment patterns, and inner world.

Most importantly, I show up as a therapist: I provide a warm, safe, and non-judgmental space where clients can be fully seen, heard, and validated. I understand that reaching out for help can feel overwhelming, and I meet clients with compassion, patience, and respect for their pace.

I am committed to helping clients work through inner emotional conflicts so they can move toward a more stable, fulfilling, and connected life—not just symptom relief, but real, lasting transformation.

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.

I believe therapy should feel like a space where you can finally exhale. I strive to create an environment that is supportive, honest, and free of judgment; a place where you feel truly seen and emotionally safe. My approach is collaborative and practical. I don’t just help you understand why you feel the way you do; I help you build real tools to navigate it.

I earned my degree from Cal State Fullerton and have extensive experience working in addiction treatment, eating disorder recovery, and women’s issues. Supporting women is especially meaningful to me. I am deeply passionate about helping women navigate challenges related to self-worth, body image, relationships, boundaries, life transitions, and identity. I understand how trauma, societal expectations, and relational dynamics can shape how women see themselves, and I approach this work with both compassion and clarity.

Together, we focus on strengthening mindfulness, emotional regulation, distress tolerance, and communication skills in ways that feel realistic and sustainable. I blend insight-oriented exploration with concrete strategies, because meaningful change happens when insight meets action. My goal is to help you better understand your patterns, feel more confident managing your emotions, and move forward with greater clarity, self-trust, and resilience.

I am a seasoned behavioral health and forensic psychology leader with over 20 years of experience in county, correctional, and community settings. I hold a Ph.D. in Clinical Psychology, two master’s degrees, and I am a licensed Marriage & Family Therapist as of 2019. My work centers on trauma‐informed care, substance use, sexual abuse victims and offenders, crisis intervention, and forensic experiences.
