Brian Lopez

Brian Lopez

Brian started as Executive Director of the DSASTX in February 2020 after fifteen years of experience working with individuals challenged with intellectual and developmental disabilities and their families in the San Antonio area. Brian has worked with local direct service providers and the Alamo Local Authority/AACOG, served as Regional Director of Service Coordination for Hill Country MHDD Center in Kerrville, and was the Associate Director of Adult Day Services and Child Care Services at The Arc of San Antonio.

Brian is a strong advocate for inclusion and acceptance for those with Down syndrome and other disabilities in schools and our communities. He believes that when you judge someone based on a diagnosis you will then miss out on their abilities, joy, and love.

Brian has a love for sharks, all things Star Wars, the Texas Longhorns and the Dallas Cowboys, and of course Dr. Pepper!

Magaly Diaz

Education Director

Magaly Diaz

Magaly studied fashion merchandising at the University of the Incarnate Word, but after having a child with Down syndrome, became interested in serving the disability community by learning how to advocate for them. She spent 2 1/2 years as the Regional Coordinator for Partner's Resource Network, a non-profit organization supporting parents of children with disabilities. The DSASTX has made a significant impact on her family's life and introduced her daughter, Audrey, to lifelong friendships.

In her spare time, Magaly enjoys home projects, brunch, and spending time with her family.
