Kristin deviated from the family flock by attending Indiana University, earning an English degree. She worked as an editor and writer in Colorado and Michigan before the siren call of Blackstone brought her back to Indiana. Kristin started at Blackstone in 2002 and has since learned to love the intoxicating world of oil analysis. When she’s not working on the website, creating newsletters, doing HR stuff, or writing reports, Kristin enjoys running, swimming, gardening, and working on visiting all 50 states with her husband and kids.
