Timothy Mahoney
Coldwell Banker Gundaker

If you have shopped for (or purchased) a brand-new home in St. Louis during the last 30 years, there’s a strong chance Tim Mahoney had some connection to your community.

That’s because Tim has represented more than 200 residential developments throughout the St. Louis metropolitan area featuring every conceivable homestyle from starter homes, executive homes, estate homes, custom homes, condominiums, townhomes, villas, and lofts in every available price range from $60,000 to $8,000,000+

He has marketed master planned communities, multi-builder communities, world-class golf course communities, country club communities, "55-or-Better" aging-in-place communities, and rental apartment complexes in St. Louis, Missouri; St. Charles County, Missouri; Illinois; Michigan; and beyond.

Tim Has Helped Sell Tens Of Thousands Of Homes -- Valued At Hundreds Of Millions Of Dollars.

Therefore, it was not surprising when Tim made the decision to expand his marketing capabilities, become a realtor, and join the #1 broker in the #1 office in St. Louis - Coldwell Banker Gundaker Town & Country.

“I love real estate. It’s in my DNA. I have been involved in it my entire professional life, and I felt this was a natural extension of my business and experience. And one of the main things my 30+ years of experience has taught me is, by far, branding and marketing are the great differentiators. 

Anyone can put a sign in the yard, but the question today’s sellers need to ask their prospective agent is: What Is Your Marketing Strategy?

You need to be totally satisfied with their answer. Most importantly, you should do your own homework to see if the agent actually does what they say they do and can demonstrate it. It’s the only way to get everything you’re asking for. If you’re unsure, by all means, interview someone else. As you can imagine, most relationships of this nature don’t improve over time,” he said.

Back In 1987, Tim got his start at J.L. Mason of Missouri, the parent company of Mason Homes, which at the time was Missouri’s Largest Homebuilder. Jack Boggan, his former college professor, came calling and Tim didn’t hesitate, because landing your first job in marketing back then was no easy task. About a year later, he left Mason Homes to again pair up with his former teacher who had started Boggan Advertising, an agency specializing in homebuilder advertising. Then in 1990, Tim founded 681 Group and continued working with scores of building industry leaders, in addition to, many other businesses. To view the portfolio visit

“Real estate is always exciting. It's great to be able to work in an industry where everyone can be your client. And I am so excited to be able to work one-on-one with families every step of the way - to achieve their American Dream,” said Tim.
