Addiction therapists & psychiatrists in Santa Ana, CA

I am dedicated to helping individuals make meaningful, lasting changes by developing coping skills that fit their unique life experiences. With over 20 years of experience in addiction treatment and mental health services, I bring a grounded, compassionate, and client‐centered approach to therapy. I believe that you know yourself better than anyone else, and my role is to support you in uncovering your strengths, healing from past experiences, and building a life that feels more balanced and fulfilling.

My specialties include substance use disorders, anxiety, PTSD, trauma, and co‐occurring mental health challenges. I am committed to helping clients improve their relationships, reduce stress, and strengthen their sense of self‐worth. I focus on the whole person—mind, body, and environment—because growth in one area naturally supports growth in all others.

I enjoy working with individuals in the recovery community, first responders, and those who have experienced traumatic childhoods. I don't just talk the talk, I walk the walk.

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.

Reaching out for help can be a BIG deal and I am here to make therapy a space where you can grow, be challenged, and learn how to live a life YOU are happy with. Have you been feeling an increase in Anxiety? Are you a young adult trying to navigate the world and figuring out where you fit? How about someone experiencing substance misuse? These are the areas I get excited to help people manage. My goal is to help you gain the control you deserve to have over your own life.

Have you considered talking to someone but you’re not sure where to start? As a Licensed Marriage and Family Therapist, I am trained in working with people and specialize in young adults, as well as treating co-occurring disorders. I believe individuals experiencing addiction are often times also managing mental health symptoms. I treat the WHOLE person.

I have over 10 years of experience working with both adults and youth. I'm licensed in California and have been trained in Cognitive Behavioral Therapy, Dialectical Behavioral Therapy, and Mindfulness.

People come to therapy for different reasons. Sometimes something clearly isn't working. Other times, life may look okay on the surface, but you feel stuck, disconnected, or unsure about what you want next. I work with adults navigating anxiety, depression, grief, relationship difficulties, and major life changes, as well as those wanting to better understand themselves and the patterns that keep showing up in their lives.

My approach is warm, grounded, and curious. I’m interested in understanding what’s happening beneath the surface, including your thoughts and emotions, the patterns you've developed over time, and how your experiences show up in your body. Therapy can be a place to make sense of those experiences while finding ways to move forward that feel meaningful and true to you.

As a bilingual and bicultural therapist, I offer therapy in both English and Spanish. I strive to create a space where you can speak openly, feel understood, and explore your experiences in the context of your relationships, culture, identity, and the life you’ve lived.
