About the executive committee
The COABA Executive Board is the governing body responsible for overseeing the association’s operations and strategic direction. Comprising the president, president-elect, secretary, treasurer, three directors, and (if available) one student representative, the Board ensures COABA’s mission is upheld. While committees or individuals may be appointed to support operations, only Board members hold voting privileges. The Board meets at least annually, with additional meetings called as needed, adhering to Roberts Rules of Order to maintain structured and effective governance. Board members are expected to remain in good standing, with vacancies filled by a majority vote until the next election.

Bethany Coop
Bethany Coop is a dedicated and passionate professional who has committed her life to
positively impacting the lives of children with significant developmental delays and their families.
As a Board Certified Behavior Analyst (BCBA), she has become a driving force in behavioral
analysis, particularly in mentorship and advocacy work within the field of profound
developmental disabilities. Currently, she is pursuing her PhD to further advance services for
children with profound disabilities, deepening her impact in the field.
Bethany’s journey in behavior analysis began with a deep-rooted commitment to advocacy and
equality. As a high school student, she collaborated with Proud Young Americans for Truth to
raise awareness about the Americans with Disabilities Act, educating voters on the importance
of this landmark legislation. This initial spark of advocacy was fueled by personal experiences
when her first child was diagnosed with developmental disabilities, inspiring her to champion
equal rights and access to essential services for individuals with disabilities. Since those early
days, Bethany has had the privilege to share her knowledge and expertise on numerous boards
and committee appointments all focused on supporting families within our communities.
Bethany’s academic journey led her to Penn State, where she embarked on becoming a BCBA.
Her passion for helping children with developmental delays and nurturing the next generation of
behavior analysts led her to establish Over the Rainbow Behavioral Consulting. Through this
company, Bethany provided essential support and therapeutic services to families in rural
Colorado. After 15 years of successfully running the clinic, she has now retired from clinic
ownership to focus on mentorship for BCBAs working in the profound disabilities field, as well as
continuing her advocacy efforts. Bethany’s current role at ClearPath Behavioral Solutions allows
her to guide the next generation of BCBAs, empowering them to provide ethical and
compassionate care.
Beyond her professional accomplishments, Bethany is a devoted mother to two children and
has shared over 20 years of marital bliss with her husband. Their home in Colorado is lively,
filled with love, laughter, and a menagerie of beloved pets.
Bethany Coop’s life is a shining example of dedication, compassion, and advocacy, inspiring
those who aspire to make a meaningful difference in the lives of others, particularly children and
families facing developmental challenges.
