I grew up in Iowa and developed a penchant for weather at a young age watching severe weather roll through during the spring and summer (TWC was one of my most-watched channels as a youngster). I began chasing severe storms during my undergraduate years at Iowa State University and still chase on occasion when I have time. I have also developed photography skills, which I use not only for documenting storm chase adventures but also the wonderful landscape of the western US, including on hikes. I like to hike Colorado’s bigger peaks, including thirteeners and fourteeners. Otherwise I like to be active by running and cycling, reading non-fiction, visiting Colorado microbreweries with my wife, and spending time with our three dogs. I can occasionally be found go-karting as well.
