Trauma and PTSD therapists & psychiatrists in Ontario, CA

Great to meet you!

As a Licensed Clinical Social Worker, I believe prioritizing mental health is key to happiness and stability in life. Asking for help can be one of the toughest challenges, so congratulations on taking that first step! I’ve been practicing for 10 years, and my main focus are adult clients who are struggling with PTSD, anxiety and depression.

I believe healing begins with meaningful connection. My work with cancer patients and their families has deeply shaped my understanding of pain, loss, resilience, and the complexities that relationships face during times of crisis. I support adults of all ages in navigating challenges such as anxiety, depression, loneliness, grief, and relationship concerns, offering both compassionate guidance and practical, effective tools for growth and healing.

I specialize in helping individuals navigate life transitions, anxiety, depression, narcissism, codependency, people-pleasing, and trauma. My approach is client-centered and collaborative, tailored to your specific needs and goals.

I was always drawn to people who went unseen or unheard. Others told me I had a calm voice and that they could tell me anything. That led to a lifelong study of how people free themselves from their own patterns, later deepened by psychoanalysis and professional work in eating disorders, addiction treatment, and managed care settings like Kaiser.

I believe that each individual has a purpose and that sometimes we need assistance in finding our purpose. Let me help you find your own purpose or regain focus on your life's path to feeling satisfied in the life you are living. I am available via online or in person and licensed in California and Arizona.

I help clients break the cycle of self-defeating patterns by exploring the lasting impact of early attachment wounds—especially the often unspoken pain of under-mothering and emotional neglect. My approach is grounded in compassion, curiosity, and the belief that healing begins when we de-stigmatize shame and make space for our unmet needs.

With certification in EMDR and advanced training in Internal Family Systems (IFS), I support clients in working through trauma, grief, and relational challenges. My background also includes working with first responders and professional athletes navigating high-pressure roles and emotional resilience.

Whether you're facing anxiety, grief, or feeling stuck in old patterns, I provide a steady therapeutic presence—offering insight, empathy, and deep respect for your healing process. Together, we work toward greater self-trust, healthier boundaries, and a renewed sense of wholeness.

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 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.
