Theresa Haywood-Castile

VP of Food Services

My name is Theresa Haywood-Castile. Since becoming a part of the SAAF family in 1996 I have been lucky enough to experience the many departments and see firsthand all they do for our Texas communities. In 1999, I was an HIV test counselor and shortly after in the early 2000’s I became a Volunteer Coordinator and worked with the City of San Antonio probations program! In 2011, I took a small leave of absence when I was diagnosed with (AML) Acute Myeloid Leukemia but I returned in 2012 stronger than ever and ready to get back aiding in the fulfillment of SAAFs mission!

Being allowed growth and the ability to try out different roles is what led me to discovering that my true passions were in the kitchen! The heart and soul of SAAF – the one place that allowed for one on one, in depth, interaction with our clients. With a little hard work and determination I am now VP of Food Services. The position I am in has allowed me to build a dedicated team focused on providing the best meals & services to our clientele.
