Jonathan Ullman – Executive Director & CEO

Jonathan Ullman is Executive Director & CEO of The Mob Museum, the National Museum of Organized Crime and Law Enforcement. Reporting to a 20-member Board of Directors, Jonathan is responsible for leading the organization that will operate and grow this world class museum.

Prior to joining The Mob Museum, Jonathan spent over 17 years in a variety of management and leadership roles within the nonprofit museum industry. Most recently, Jonathan was the president and COO at the National Soccer Hall of Fame, a private institution sanctioned by the US Soccer Federation that included a 30,000 sq. ft. museum, four world class soccer fields, and multiple retail, concession, and meeting facilities. During his tenure, Jonathan facilitated a strategic plan that ensured the financial sustainability of the organization through a dramatic change to the operating model and relocation of the collections. This institutional “reinvention” was widely embraced by board members, donors, and key community and governmental stakeholders.

Jonathan’s museum career began at Liberty Science Center, where he was intimately involved in operationalizing the Center upon its opening in 1993. Over the years, Jonathan served in numerous capacities, with responsibilities ranging from intensive staff and program oversight to strategic planning and external relations. His purview included the comprehensive management of the public operation, as well as the implementation of educational programming through learning experiences that occurred onsite, offsite, and online. As a member of the eight-person Steering Committee, Jonathan’s contributions helped Liberty Science Center achieve the status of the most visited museum in the state of New Jersey, surpassing more than 9 million guests in a twelve-year period. Jonathan’s efforts also included extensive capital planning and business development. This culminated in 2007 with his coordination of reopening preparations following a $109MM renovation and expansion.

Jonathan earned his Bachelor’s Degree from Rutgers College and his Masters of Business Administration from Rutgers Business School. A believer in the importance of community, Jonathan has also served on a number of nonprofit boards.
