Emphasis in Child & Adolescent Development
Since the beginning of her career, Lynn has been focused on child and adolescent development. She specializes in psychological assessment, differential diagnosis, and trauma-informed care, in addition to having specific training in Dialectical Behavior Therapy, parent-child psychotherapy, and suicide assessment.

Lynn focuses on the importance of developing authentic relationships to strengthen personal character, purpose, and emotional maturity. She appreciates the challenge of understanding each student’s unique life story and uses her optimism, passion, humor, and kindness to help find the key components that can support students in building a life they want to live.
What makes you happy about working at Embark at Flathead Valley?
Embark at Flathead Valley provides an opportunity for me to be part of the students’ everyday routines and interactions. Seeing the students function in multiple environments allows me to build a deep understanding of their strengths and areas of need. Using that knowledge I can create growth experiences within a multidisciplinary team that can be implemented and practiced in all areas of functioning. The short-term residential environment offers a unique perspective, as a therapist, to see a student’s functioning in real-time and provide in-the-moment strategies to support the students in utilizing healthy skills.
What are your interests outside of work?
I love being outside; exploring and adventuring with my husband, son, and daughter. Some of our favorite activities are skiing, rock climbing, hiking, mountain biking, swimming, and traveling. I also enjoy relaxing with a good book and learning new things.
