Our philosophy at Coldwell Banker Gundaker is that everything we do is done to “Help Agents Live Exceptional Lives". We do this as a management team by putting our focus on our “Core Four.” Core Four are the four areas in which everything we do must fit. They are:

“Production Power” We help agents sell more homes, net more money and operate more efficiently.
“Coaching to Confidence” We help agents expand their sales skills and business development capabilities through effective education, support and coaching.
“A Culture of Awesomeness” We provide an inclusive environment that is fun, supportive and collaborative. We are a company that generates pride and inspiration.
“Wealth Builder” We provide opportunities that agents can use to grow their personal wealth with real financial strategies. We believe your best years are ahead of you.

If you would like to learn more about how the Core Four can work for you, contact Jason today:, 314-803-3638 or 636-379-8500.

I'm a buyer, what do I need to do?

In today's market, in order to be considered a ready, willing and able buyer, you must be pre-approved for your loan! Sellers want strong contract terms and that includes lending info as well (unless, of course, you are a cash buyer). The Coldwell Banker Gundaker K&N Office provides this very important service so you can be well prepared before finding a home through a very experienced loan officer, Andy House, VP of Mortgage Lending at Guaranteed Rate Affinity. Contact Andy House to get that started, 314-824-1507, 636-395-6455 or email him at He works weekends if you do!
