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, a passionate hobby that continues today. 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 stay active by running and cycling, and spending time with my dog.
