Addiction therapists & psychiatrists in Sebastopol, CA

I earned my Master of Arts degree in psychology with a focus on marriage and family therapy to pursue my passion for helping others navigate life's challenges, achieve personal growth, and heal. My education and training have equipped me with the knowledge and skills to provide effective, evidence-based therapy to my clients.

I am a Licensed Clinical Social Worker with 10 years of social work experience and 5 years of experience as a psychotherapist. My experience ranges from treating children ages 5 and older to treating geriatric individuals aged 70+. I am a bilingual, Latina therapist and I conduct therapy in both English and Spanish. I have worked in a variety of settings including community mental health and private practice treating a range of mental health issues such as depression, anxiety, OCD, PTSD, co-occurring disorders, and more. Much of my work has been focused on working with the Latino community in Southern California as well as disadvantaged communities of color.

I have 40 years experience in the mental health field in multiple roles, I believe listening and believing in the person is the most important way to practice therapy.

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.

I graduated from Fresno Pacific University-Biblical Seminary in 2014 and obtained my license as a LMFT in 2018. My experience has been working with children, adolescents, families (4 years) and adults (11.5 Years). I have 11.5 years' experience with co-occurring disorders to include severe mental illness and trauma. I have utilized but not limited to the following evidence practices and modalities -ACT, Strength-Base, Family psychoeducation, DBT, CBT, and person centered. I am currently expanding my education/training in Internal Family Systems.

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.

Do you feel like something is wrong with you? Do you wish it would all just stop and go away? Is your child acting out and you don't know why or what to do? If you have had any of these thoughts, then you're in the right place! My practice is based around what happened to us, not what is wrong with us. I am here to support & guide you in processing thoughts and feelings, reflect on experiences, learn new coping skills, and figure out next steps. I will listen, teach, brainstorm, guide and help you build tools to meet your goals.

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.
