Mr. Sean Laissle

Welcome! This is my 19th year coaching/teaching and my second year at MacArthur High School. I've spent the past 17 years at Coke Stevenson MS in NISD and made the switch to NEISD last summer. The switch moved me closer to home and afforded me more time with my family. 

I was born and raised in San Antonio. I graduated from Marshall High School and continued on to attend Southwest Texas State University where I graduated with a degree in Exercise and Sports Science. I have certifications in Physical Education and Health. 

When I am not teaching or coaching, I enjoy traveling, playing/watching sports and spending time with my family. I look forward to this school year. Go Brahmas!
