Childhood best friends, Nick Friedman and Omar Soliman, were just twenty-two when they co-founded the now iconic junk removal and moving company, College Hunks Hauling Junk. Starting as an idea to earn some extra money over college break in a beat-up cargo van, the duo has grown College Hunks into a $300 million national franchise with more than 100 locations – truly demonstrating what it means to be both bold risk takers and modern leaders. The company and founders have been widely recognized and acclaimed for their world-class culture and service, as well as their progressive approach to doing business in the 21st century. Through lessons-learned from their monumental business growth, the pair discuss what it means to create a purpose-driven, customer-centric organization, while also sharing their secrets to success: patience, persistence, and standing out in a crowded landscape. Building their company around visionary leadership, Friedman and Soliman showcase how to craft a world-class organization by developing an entrepreneurial culture of strong, reliable teams.
