Karl Dettmann grew up in Madison, WI and like any good Madisonian, he spent his summers as a kid swimming at the neighborhood pool.  Karl was a Parkcrest Penguin and swam his first competitive race at the age of 5.  He has a twin brother David, and they were each other’s biggest competition. Karl finished up his swimming career as an NCAA® athlete, swimming for the University of Wisconsin La Crosse with David at the age of 23.  David is also a Northwestern Mutual Wealth Management Advisor in the Twin Cities, MN area.    

When Karl wasn’t in the pool, he also had quite the entrepreneurial itch.  At the age of 12 he started his first business designing websites for small and medium sized businesses in the Madison area.  Thankfully a childhood mentor, Steve McKenzie, took him on as a business partner. Currently his involvement in this business is limited as Karl's passions have moved to the area of helping businesses and people with their finances. When Karl wasn’t tied up with Swimming or Website design, he also was a part of starting a photography business with his brother.

Karl graduated from the University of Wisconsin-La Crosse with a BA from the business school.  From there he had an opportunity to work with a great team of people at American Girl and for the men reading this…Hotwheels.  He worked for Mattel the toy company who owns many different brands of toys.  Karl worked in the E-Commerce arena at Mattel for 4 years helping to make sure kids got their toys in time for Christmas.  Karl is a technology geek at heart and can talk the geek talk.

He is also a man of Faith, and does think that all things happen for a reason.  A few years ago he would have never pictured himself being a Wealth Management Advisor. At that time, Karl actually worked with a financial advisor he didn’t like at all and at the time Karl didn't have a good view on the industry.  But after a series of eye-opening events, Karl saw the impact he could make in people's lives, in the community and for his family.  He took the leap of faith and hasn't looked back.  Karl is thankful every day that he has the opportunity to listen to clients and to teach and energize them about their future.
