Hello! My name is Ian and I have been addicted to weather since I was about 3. My hero growing up wasn't the police man, superman or even a teacher. Mine was a Meteorologist named Percy Saltzman. I have been chasing storms for a long as I can remember and according to my doctor, I am NOT crazy. I am a storm chaser, weather freak, Social Media Educator, amateur Photographer, speaker and father of Twins.
