About Our Founder

I am the Founder/Owner, and Executive Director of Childhood Autism Services Inc (CAS). The organization was established in August 2011 to provide Applied Behavior Analysis (ABA) services for children with autism spectrum disorder (ASD). Since then, our organization has grown significantly, thanks to our dedicated team of BCBAs, BCaBAs, and RBTs who meet the unique needs of every child and family.

My career began in 1987 as a special education teacher, focusing on early intervention for children with a variety of neurological and developmental disorders. In 2011, the company began offering home-based ABA services and I earned my master’s degree in education from the College of Saint Mary in Omaha, NE. I became a Board-Certified Behavior Analyst in 2013, receiving my certification from Florida Institute of Technology.

At CAS we are guided by respect, communication, and kindness. We treat every child with dignity and compassion, fostering a nurturing environment. Our clear and empathetic communication helps build strong, supportive relationships, ensuring the best outcomes for each child.

“A failure is not always a mistake; it may simply be the best one can do under the circumstances. The real mistake is to stop trying.”

– B.F. Skinner

Employee & Funder Relations

After many years of managing people and finances in the Hospitality and Non-Profit industries, I chose to join CAS while it was still a small startup company. I recently settled into the Human Resources and Funder Relations role and have an insider view of the growth within CAS and in the ABA industry as a whole. I have enjoyed researching and developing benefits and policies for our amazing staff as well as creating relationships with insurance funders who are still learning more about ABA benefits and what we do.  In my personal time I get to enjoy my children and six grandchildren alongside my husband.  We like to attend new and fun local events and travel any time our schedules allow.
