Mike Sittig believes that his educational background helped prepare him for the success he and his organization have achieved. “My education provided me with a solid foundation for the future and an academic base for my chosen career. I am especially appreciative of my studies at Tallahassee Community College. For me, TCC was a community within a community and I found the professors and administrative staff as committed to my education as I was.”

Mr. Sittig cites working with journalism chair and student newspaper advisor Judith Jolly as a reporter covering the legislature as “particularly rewarding.”

Mr. Sittig's professional affiliations include Leadership Florida, with service on their Board of Regents and Chairman of the Program Committee; Ex-officio member of the Legislative Council on Intergovernmental Relations; Board of Directors of the Southern Municipal Conference; Board of Directors of Florida Tax Watch; and Secretary of the Home Rule Committee.

Among his most significant achievements are successfully protecting the interests of Florida's cities for nearly 20 years, amending the State Constitution to prohibit the Legislature from mandating un-funded programs on cities, providing $60 million a year in insurance products to cities, providing $400 million a year in financial products to cities, and advocating diversity to build successful coalitions.

He served on the TCC Alumni Association Board of Directors as Secretary/Treasurer and was instrumental in establishing the group.
