Practitioners You Can Trust

Westside Behavior Therapy was established in 2015 as a small, home-based practice serving just a few clients. After recognizing the increasing need for services, we opened the doors to center-based services in 2016. We are committed to a high standard of care.

Kelsey Townsend, M. Ed., BCBA, LBA

Kelsey earned a Master of Education specializing in Applied Behavior Analysis from Arizona State University in 2013 following undergraduate work at the University of Oregon. She has been practicing ABA since 2012. She is a Board Certified Behavior Analyst® (BCBA®) and a Licensed Behavior Analyst (LBA) in the State of Oregon. Kelsey has acquired a wide range of experiences with evidenced-based interventions in a variety of settings including center, home, community, and school-based environments. Her primary area of expertise is providing early intervention, ABA-based services to children on the Autism Spectrum.​ Although the ABA needs of the community are great, she feels it is important to keep her practice small serving only 15-20 families at a time in order to provide an extremely child-centered, individualized ABA experience. When she's not at work, she spends her time with family including her husband and three children.

She went back to graduate school to further her career and support her passion for ABA. After graduating from Arizona State University with a Master of Education in Curriculum and Instruction of Applied Behavior Analysis, Serena became a Board-Certified Behavior Analyst® in the winter of 2018. She feels truly fortunate to be a piece of every child’s puzzle that comes through the Westside doors. In her free time Serena enjoys exploring the beautiful Pacific Northwest with her Beagle in the passenger seat.

With only a few more months of practical hours left to accumulate, Melissa plans to sit for the BACB® board examination in February 2020.
