Clinical Experience

​​My clinical journey began in community mental health over a decade ago, where I had the privilege of working closely with adolescents, parents, and families navigating some of life's most challenging moments. Those years taught me how to meet people where they are — learning to understand the layers of complex family systems and offering support that honors both the individual and the family as a whole. I also spent time as a program supervisor, mentoring and coaching developing clinicians in their work with children and adolescents. 

 

Prior to opening my practice, I deepened my clinical roots at the Wise Mind Institute where I dedicated myself to specialized training in Dialectical Behavior Therapy (DBT) and Radically Open DBT (RO-DBT). These approaches strengthened my ability to support adolescents and adults facing challenges with emotion regulation, high-risk behaviors, over/underachievement, and treatment-resistant depression and anxiety.

 

Though my clinical foundation includes extensive evidence-based training, I find that

my work today is most alive in the relational space — in the

genuine, moment-to-moment connection between therapist and client.
