RE/MAX Enterprises & RE/MAX of Naperville


About US:

In 1976 Jack Brennan, an ex-Chicago police officer, and his wife Barbara Brennan opened up Brennan Realty in Naperville.  After 2 years of setting up a successful independant real estate office, Jack and Barbara decided to team up with an unknown company that had only been founded 5 years earlier in Denver and only been in Illinois for months.


In 1978 Jack and Barbara traveled to Denver in order to go through management training with this new company. 


This unknown company was RE/MAX!


One week later after returning home from Denver, they came home to an empty office with the exception of 1 agent.  "Was it tough at first? Heck no," Jack said.  "Everyone just thought we were nuts.  When they started to take us seriously, that's when it got tough."


Over the next year Jack and Barbara fought on and were able to restaff their new RE/MAX Office with agents and people started to take them serious.  In 1979 they purchased 2 more offices, both of which filled to capacity.


Throughout the years many changes have occured.  Although, Jack and Barabara have stepped down from the day to day operations.  Their hard work ethic and determination can still be felt everyday.  With the day to day operations being handled by Oldest son John Brennan (President/ Broker Owner,) and Michael Brennan (Vice President).
