Now Providing DBT treatment to adults and Teens!
About Us
Annie Florin, LCSW, she/her
Founder & Clinical Lead
(406) 201-8380
Annie Florin has been a licensed clinical social worker since 2016. She started working in children’s mental health as a special education teacher in a day treatment program in San Francisco in 2003. She completed her Master of Social Work degree at the University of Montana in 2016. She’s worked in schools, community mental health, outpatient psychiatry clinics, and acute psychiatric inpatient for adolescents.
Annie’s theoretical orientation is woven together from attachment theory, systems theory, feminism, and trauma. Her approach is client-centered and strengths-based. Her therapeutic modalities include psychodynamic therapy, DBT, Acceptance and Commitment Therapy (ACT), and Cognitive Behavioral Therapy (CBT).
DBT for adolescents is Annie’s passion because it integrates attachment, family systems, self-empowerment, and behavior change. And because teenagers show up to life with an authenticity that’s energizing to her.
Outside of work she is a deep thinker & feeler, a wife, and a mother. She likes to go to bed early, get her hands dirty in her gardens, trail run with her lab/pit mix, Pepper, and embarrass her children with too much affection and “bad” jokes (they’re actually pretty decent jokes).

She combines a warm, compassionate presence with creativity, irreverent humor, and an authentic, “radically human” approach to the therapeutic relationship.
Jen’s clinical approach is informed by several therapeutic modalities, including Dialectical Behavioral Therapy (DBT), Acceptance and Commitment Therapy (ACT), and Compassion-Focused Therapy (CFT), with a theoretical orientation firmly grounded attachment, interpersonal neurobiology, behaviorism, sensory integration, and neuroscience.

Originally hailing from New York, Jen accidentally began a love affair with Montana in 2009. When not at work, Jen can be found admiring and collecting cool rocks, savoring a good cup of coffee, enthusing about the Enneagram, and wandering in the woods at golden hour with her three dogs.
