Ms. A. Lasater

I was a military child so I moved for several years. I call San Antonio my home town because I moved here when I was 10 years old. I graduated from Judson High School in Converse, TX. I joined the Air Force as a Still Photographic Specialist and stayed for 7 1/2 yrs. I have also worked with nurses as a scheduling coordinator. My degree is in Criminal Justice with an emphasis in Forensic Science. I have been a high school teacher for 9 years. I was a chemistry and IPC teacher in Pleasanton ISD before coming to Madison High School.

Outside of teaching, I am a mother to two beautiful daughters. My oldest is a labor and delivery nurse and is married. She gave me my two beautiful granddaughters. My youngest daughter is in college studying to be a math teacher and she is also working to help put herself through school. 

I enjoy teaching chemistry and cannot wait to teach your child this year. This will be a great year.
