Mr. Roy Thelin

I am the Computer Science teacher at RPHS. Before starting here in 2014, I was teaching in Richardson ISD for six years. My background, however, is not in education. 

I have spent all of my life on the move: 18 years as a military dependent, 24 years in the military, 2 years as an IT network manager, and 4 years as an IT contractor in Southwest Asia.

When I am not doing teacher related work, I am a record-holding amateur powerlifter and multi-site Webmaster.
