Most chef-restaurateurs know that it's hard work getting a restaurant off the ground, but perhaps no one around here understands it better than chef Zak Groh. A Milwaukee-area native, Groh got his start at his family's custard stand before jet-setting all around the world gaining kitchen experience. A few years ago he came back home and in 2013 he launched Whisk Culinary, catering business that specializes in inflight meals for private fliers.
