Joannie and her late husband Martin Stein established a small land-development business, Regency Realty, in 1963. At first they built a few houses and apartment complexes and did some land brokering. Regency Realty turned into a regional success and they built Regency Square Mall, Jacksonville’s first big shopping center. In later years her son, Hap Stein, took over as chairman and chief executive officer of what is now Regency Centers, Inc. Joannie served as chairman from 1963-1997 and as chairman emeritus since then. Because of her involvement with Regency, a lot of things came her way. She served as chairman of the Jacksonville Branch of the Federal Reserve Bank of Atlanta and on the board of directors of Barnett Banks of Florida.
Joannie earned an associate of arts degree from Briarcliff Junior College.
