After Hours

After spending most of my childhood and professional life living overseas, I’m happy to have settled in the Twin Cities with my family. In my free time, I enjoy chasing after my toddler, trying out new restaurants, walking along the Minnehaha Parkway when the weather’s nice, and attempting to finish a crossword puzzle.
