Mike Rosenthal received both his undergraduate degree (B.A. with honors, 1977) and his law degree (J.D. 1980) from the University of Florida. After graduation from law school, Mike served four years as an Assistant Attorney General for the State of Georgia. Following his entry into private practice in 1984, Mike remained active in service to the State of Georgia, both in the Governor’s Office of Consumer Affairs (as Coordinator of Special Projects) and as a Special Assistant Attorney General. Mike’s practice primarily involves the representation of franchise, professional franchise and service industry clients, providing both day-to-day business counseling and advice, as well as litigation services when necessary.

Mike has represented numerous start-up franchisors, sellers of business opportunities and other sellers in licensing and distribution arrangements. His practice includes counseling clients on the best way to format their business, franchise, licensing or other. Mike prepares and files necessary government registrations and disclosures, addresses regulatory problems and concerns on behalf of clients and, when necessary, represents his clients in court to protect their interests. Mike particularly enjoys working with clients in the planning stages in order to avoid regulatory and other issues.

Mike is one of a very small number of attorneys nationally to specialize in representing sellers of business opportunities. Mike is a member of the American Bar Associations’s Forum on Franchising and of the Georgia Bar’s Franchise and Distribution Law Section.

Until its recent sale for $6.2 Billion, Mike served as an independent Director of Inland Retail Real Estate Trust, Inc. (IRRETI) a public real estate investment trust which was one of the largest owners of retail space in the Southeast. IRRETI managed over 300 retail shopping centers or single tenant properties, primarily east of the Mississippi River.

Mike is an active University of Florida alumnus, serving on the Alumni Association’s Atlanta Regional Council and the Alumni Advisory Board to the Department of Political Science. Needless to say, Mike also enjoys Gator football and basketball.
