Addiction therapists & psychiatrists in Rancho Cucamonga, CA

If you’re struggling with your relationship with food, your body, or feeling stuck in cycles of restriction, bingeing, or guilt, you are not alone—and you don’t have to face it by yourself. In my private practice, I specialize in working with individuals navigating eating disorders and disordered eating.

I provide compassionate, individualized therapy for adolescents and adults experiencing anorexia, bulimia, binge eating disorder, chronic dieting, and body image concerns. In addition to eating disorder treatment, I work with children, teens, and adults facing anxiety, depression, trauma, personality disorders, substance use, and challenges related to identity and the LGBTQIA+ community. I am committed to creating an affirming, inclusive space where clients of all backgrounds feel seen, respected, & supported.

I am a Licensed Clinical Social Worker (LCSW) with 28 years of experience in the mental health field. I earned my Master of Social Work (MSW) from the Hunter School of Social Work and have lived and practiced in California for over three decades. My professional background includes extensive work with older adults, individuals experiencing homelessness, and adults living with severe and persistent mental illness. I am known for my patient, compassionate, and attentive approach, and I strive to be fully engaged and present with every client I serve. My goal is to provide thoughtful, individualized support that helps clients feel understood and empowered in their therapeutic journey.

I have been working in private practice for a few years and before that I worked in non-profits with a variety of individuals and groups. I am the parent of two adult sons and have three grandchildren that I thoroughly enjoy spending time with. I have an educational background in the study of philosophy, spirituality and counseling psychology. I have experience with helping people with histories of trauma, severe mental illness, as well as, symptoms of anxiety and depression. I also have experience and some expertise with clients struggling with substance use.

Hi, I’m Dianna Johnson, a Licensed Marriage and Family Therapist (LMFT) and Certified Addiction Specialist (CAS) with over two decades of experience helping people find hope, healing, and meaningful change. I work with adolescents, adults, and seniors navigating anxiety, depression, trauma, grief, addiction, relationship issues, and stress management.

I’m especially passionate about supporting individuals living with Borderline Personality Disorder and those who struggle with impulsivity or emotional intensity. My goal is to help you better understand yourself, build emotional balance, and create healthier, more fulfilling relationships.

Welcome. I'm Roxy, dedicated to helping you find what you are looking for in therapy. My goal is to offer a safe, compassionate space where you can heal and grow.

I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) with a DNP (Doctor of Nursing Practice) degree from the University of Massachusetts Global. I have experience working with adolescents and adults in multiple settings facing various complex mental health issues, including OCD, depression, anxiety, ADHD and mood disorders.

I’m Antionette Sob, a Board-Certified Psychiatric Mental Health Nurse Practitioner dedicated to empowering individuals to live fuller, more balanced lives. With over a decade of nursing experience and advanced training in mental health, I aim to provide safe, supportive, and compassionate care. I believe that everyone can heal and grow — sometimes we need the right tools and guidance.

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 Holly, a board-certified Psychiatric-Mental Health Nurse Practitioner with 23 years of clinical experience in psychiatric care and maternal-child health. This dual background has shaped how I see mental health: not as something separate from the rest of your life, but deeply woven into every transition, relationship, and challenge you face. My work taught me that women's mental health—especially during pregnancy, postpartum, and hormonal transitions—requires specialized understanding and individualized care.

I provide comprehensive psychiatric treatment for adults across a broad spectrum of conditions: perinatal mood and anxiety disorders, OCD, PTSD and trauma-related disorders, personality disorders, depression, anxiety, panic disorder, bipolar disorder, and schizophrenia spectrum conditions. I have particular expertise in women's mental health throughout the reproductive years, though I welcome anyone seeking compassionate, evidence-based care.

My approach is straightforward: effective treatment should fit your real life. I combine psychiatric interventions—including medication management when appropriate—with practical therapeutic strategies and lifestyle modifications that actually work for you. I'll help you understand what's happening, why it's happening, and what options make sense for your unique situation.

What matters most to me is seeing you as a whole person—not just a diagnosis. You have strengths, values, relationships, and goals that deserve attention alongside your symptoms. Whether you're managing a long-standing condition, processing trauma, navigating major life changes, or simply seeking better balance, you deserve a provider who recognizes your potential and partners with you toward sustainable wellness.

I have been a Licensed Marriage and Family Therapist for 28 years. I have worked in a Foster Care agency, as a Clinical Supervisor at a Children's Clinic in East LA and at a Drug, Alcohol, and Mental Health Facility. I also provided therapy for our military.
