About me

I’m a veteran chemistry teacher with a BS in Chemistry from Colorado School of Mines and MA in science education from UNC. I’ve taught everything from freshman physical science and PLTW intro engineering to AP chemistry and AP physics.
Outside of work, I’m a nature loving band kid who enjoys reading, hiking, rock climbing, and nerding out.
