Born on November 19, 1945, in Orange, New Jersey, Kirk was the son of the late Howard Nelson Armstrong and Hazel Viola Armstrong. At the age of 8, he moved with his family to Jacksonville, Florida, where he later graduated from Terry Parker Junior-Senior High School in 1963. He was a proud member of the school's swimming team.

Kirk earned a degree in Criminology from Florida State University and began his career in social services for the State of Florida. He later worked at the Glidden Chemical Plant—now SYMRISE—for 37 years, where he retired. He was also active in his community, serving as President of the Lake Lucina Association, and resided on Lake Lucina in the Arlington area of Jacksonville.
