Welcome to Big Sky Behavioral Therapy

"Helping children live more rewarding lives."


What We Do

Applied Behavior Analysis

Applied Behavior Analysis is an evidence based therapy that was developed from the theories and concepts of renowned psychologist B.F. Skinner. The practical application of ABA Therapy in the everyday lives of children with disabilities supports their ongoing growth and development.


We offer the following programs:

  • Assessments
    • ABLLS
    • VB MAPP
    • Vineland
  • Skill Acquisition
    • Functional communication
    • Living & Social Skills
  • Behavior Modification & Intervention
  • Parent & Caregiver Training

Our Impact

We strive to improve the lives of children and their families. Children learn new skills that help them navigate their world and we are able to reduce unwanted behaviors caused by the challenges they face. 

About Me

Jeanne Lightbody, M.Ed., BCBA

I have worked with children my entire adult life. After being a nursery school teacher for 9 years I made the decision to return to college and finish my masters degree. I worked as a Developmental Therapist and Board Certified Behavior Analyst for Connec-to-talk, Inc. in Connecticut until the fall of 2015. After  my husband and I moved to Big Sky, MT. I began working for Family Outreach in Bozeman.

At this time I am excited to bring my knowledge and skills to the residents of Big Sky with the opening of Big Sky Behavioral Therapy, PLLC.
