About Us

With our growing services extending across the Greater Seattle Region, CBC provides exceptional behavioral therapy improving the quality of life for individuals from birth to adult. Our specialized team uses Applied Behavioral Analysis (ABA) principles and practices in combination with other evidenced-based techniques to enhance individual skills needed to become as independent and successful in daily life as possible.

By providing ABA services in naturalistic environments such as home, school, and community settings, we aim to empower each of our clients to live a quality of life they deserve. At CBC we value integrity, confidentiality, innovation, diversity, and inclusion.

"Working with you over the past five years to bridge therapy and practical support has been imperative to the success of the kids and adults we serve.”
-Psychologist, Dr. Julie Osterling

Our Team

Shannon Crissey

Owner/Director
Shannon started CBC in 2015, and she hasn’t looked back since! Shannon holds a bachelor’s degree in Special Education from the University of Northern Colorado and a master’s degree in Early Childhood Special Education from the University of Washington, along with a Board Certified Behavior Analyst certificate. Her previous experience in the field includes teaching in a high school setting, as well as serving as a Lead Preschool Teacher at the Experimental Education Unit at the University of Washington’s Haring Center for Inclusive Education. She remained in this role for five years, gaining vital training from top professionals in the field at a program that serves as a model for best ABA practices worldwide.

More

In 2015, Shannon made the transition from the EEU to the Haring Center’s Professional Development Unit, where she served as an Education Resource Training Specialist for the next two years, taking clients with CBC on a part-time basis. At the PDU, she provided intensive, multi-day trainings to teachers and other professionals across the state of Washington; covering topics ranging from best practices for inclusive classrooms to addressing challenging behavior and working with families of children with developmental disabilities. These years of teaching others the concepts behind quality interventions gave Shannon a deep knowledge of best practices, making her uniquely qualified to mentor new professionals in the field. She helped them apply what they’ve learned in their graduate programs into practice in natural settings—a principle that has become central to Shannon’s vision for CBC.

Over the past decade, Shannon has taught children with and without disabilities in both self-contained and inclusive classrooms and has provided intensive ABA (Applied Behavior Analysis) therapy to children with autism spectrum disorders across multiple settings, including public and private schools; community-based camps and other recreation programs; community swimming and skiing programs; and many other settings where intervention could be embedded naturalistically. Shannon specializes in providing therapy at any time or in any setting where intervention is needed and an inclusive, naturalistic approach can be utilized. This includes, but is not limited to, grocery stores, public parks, professional photography sessions, and clients’ homes during specific routines such as mealtimes, bedtime routines, homework routines, and other challenging times of day. These past experiences continue to shape her mentorship with BCBAs and have ultimately helped her form a vision for the future of CBC that is innovative and exciting to be a part of.

Shannon enjoys spending time with her three children, Margo (8), Gwen (4), and Bear (2)—plus their cat, Monte. The Crisseys love camping in Washington and in Shannon’s native state of Montana. When she’s not enjoying the beautiful outdoors of the PNW with her family, Shannon can often be found doing a paint-by-number project, building a new LEGO set, playing ping pong, writing in her bullet journal, reading books, or listening to true crime podcasts.
