In late 2013, Annette Tipton enrolled in an experimental training program in Milwaukee for area companies with at least $1 million in revenue and ambitious expansion plans. Her goal: manage the growing pains at the van service she and her husband started in 2001 to serve seniors and the disabled. Part of an economic development initiative called Scale Up Milwaukee, the free six-month program consists of workshops led by Babson College professors on topics such as sales management and operational finance, plus mentoring sessions and networking events with fellow entrepreneurs.
