I am a licensed professional with 4 years of direct practice experience. I have experience with supporting clients in overcoming trauma, abuse, and communication issues.
Hi. I offer individual therapy by telehealth video for people who want to reduce feelings of anxiety and/or depression, and for people who are going through some big challenges in life and want some extra support with the stress.
My primary focus is working with adolescents, families, and adults, though I have a range of experience working with people of all ages and many different demographics. In particular, I have a strong background in working with at-risk youth, kinship caregivers, and foster/adoptive families. I also have a background of working with young adults transitioning to independent living, as well as adults of all ages.
I am a Licensed Clinical Social Worker (LCSW) in Colorado, and have been practicing as a therapist since 2022. Prior to this, I worked with youth, adults, and families in a variety of case management roles, including in schools, domestic violence shelters, shelters for those without housing, and families experiencing various systems involvement. This has given me an understanding of the many challenges life can bring, and equipped me with the tools to support you in navigating various barriers and difficulties.
Choosing a therapist can feel like a daunting and vulnerable step, and I want to honor the courage it takes to begin. As a Licensed Clinical Social Worker, I work with adults ages 25 to 85, bringing a long, richly lived life experience that allows me to meet you with steadiness, perspective, and compassion. My approach is grounded in unconditional positive regard—I believe you are worthy of respect and understanding exactly as you are. I can’t fix anyone, but I am very good at helping people heal themselves from the wounds life brings and to navigate the changes that shape us all.
