Addiction therapists & psychiatrists in Hillsboro, OR

I offer a calm, open, and nonjudgmental space where clients can be themselves. I am comfortable talking about difficult experiences, including relationships, grief, anger, addiction, identity, and major life changes. I also value humor, curiosity, and the interests that make each person unique. My goal is to help clients feel understood while also supporting meaningful change.

I enjoy practicing psychotherapy that is holistic and life-transforming. As an LMFT with depth specialization, I listen to your emotional heart and soul to heal the mind. The issues that you experience as an individual, couple or in relationship with family deserve attention with that kind of dedication.

Everyone deserves to have a trusted support or guide along life’s journey­­––counseling can be a place to find just that. Counseling can be like a cool drink of water in a desert oasis, helping you rejuvenate and find rest for your soul, while you’re working towards where you want to be.

My name is Celia and I am a Licensed Professional Counselor with 15+ years of experience in the field. I have worked in numerous settings which has given me the opportunity to work with a wide range of individuals at various life stages and circumstances. I specialize in working with adults who struggle with anxiety and depression. My clients often seek therapy due to feeling stuck or overwhelmed. I help by working collaboratively with you to identify patterns and past events that shape your experience today.

I help people carrying trauma, grief, or the weight of sexual abuse find steady ground again. For over two decades I've supported survivors of abuse and their families, walked alongside people through grief, bereavement, and the hardest parts of death and dying, and helped clients manage PTSD and personality disorders using a strengths-based approach. I trained at the University of Montana and Portland State University, and I'm a Licensed Clinical Social Worker in Oregon. If you're ready to feel supported while you do this work, I'd love to talk with you.

It has been a privilege to provide psychotherapy to a variety of clients for over 20 years. I have advanced clinical training in trauma, addictions, sexual abuse, mood and personality disorders, and relationships. My therapeutic style is warm, direct, and encouraging. I provide support as you examine core issues and change underlying patterns of behavior or simply gain perspective concerning a recent issue.

I’m a Licensed Clinical Social Worker (LCSW) with a Master’s in Social Work from Portland State University. I work with individuals navigating trauma, anxiety, depression, and substance use, and I bring experience from interdisciplinary behavioral health settings where care often intersects with complex life circumstances.

My approach is collaborative, direct, and rooted in the understanding that healing doesn’t happen in a vacuum. Mental health is deeply shaped by culture, community, history, and systems of power. Part of my work is intentionally engaging in a decolonizing approach to therapy—honoring lived experience, questioning one-size-fits-all models of care, and creating space for clients to define healing on their own terms.

I integrate frameworks such as American Society of Addiction Medicine and Substance Abuse and Mental Health Services Administration as supportive tools—not rigid rules—while drawing from motivational interviewing, trauma-informed care, and relational work that centers respect, autonomy, and real connection.

I offer a focused practice in ketamine-assisted psychotherapy (KAP), with careful attention to preparation, safety, and integration. This work is not just about the experience itself, but about making meaning of it in ways that align with your values, identity, and community.

I have been a counselor for more than 30 years. I remain passionate about making a difference in the lives of others and believe that genuine caring is an essential element to an effective counseling relationship. Over the years I have worked with clients with significant trauma and loss. I consider it a privilege to stand with another individual as he or she resolves great pain. I specialize in treating clients with trauma, relationship issues, and borderline personality disorder.
