Mrs. Sarah Chandler

I graduated from Roosevelt High School class of 1995. I went earned my undergraduate degree at Southwest Texas State University. I worked at the South Texas Blood and Tissue Center for a year before starting my teaching career in SAISD.  I taught at Roosevelt High School from 2002-2023. 

I have been married since 2003 and I have two of the most amazing children.  My son graduated from DATA in 2023 and my daughter will graduate from Madison in 2026.   I am the second oldest of seven children. All of my siblings graduated from NEISD schools.  When I am not at work I love to read, quilt, take pictures of my children and do other crafts.

I am very excited to be here at Madison.  I look for meeting you and getting to know you!
