About me
Duke Lee holds a degree in finance from the University of Wisconsin-Milwaukee, combining financial expertise with the discipline of martial arts to bring a unique approach to his role. Duke is a 6th-degree black belt in Taekwondo and a red belt in Gum Do, a Korean sword martial art. His martial arts journey began at age 7 in South Korea, instilling values of integrity, discipline, and dedication that define his work today.
Since 2007, Duke has served as the head instructor at the Germantown location of JK Lee Blackbelt Academy, where he has taught since he was 17. With over 20 years of experience, he is a highly respected taekwondo competitor, referee, and coach, contributing to tournaments from local events to international championships. His accomplishments include winning the Tri-State Tournament in 2000, earning the title of Grand Champion, and officiating as a center referee at JK Lee tournaments. He has also served as a referee, translator, committee member, and coach at multiple Hanmadang National Championships.
Duke is deeply committed to his community, leading charitable initiatives like JK Lee’s annual Board Break-a-thon for Wisconsin's Children's Hospital. He has trained hundreds of children in bully awareness and prevention and conducted self-defense seminars for adults. His students hold him in high regard for his mentorship and positive influence.
Inspired to take on new challenges, Duke became a financial representative to expand his knowledge of retirement planning and to share this knowledge with others. He plans to host financial seminars for his Taekwondo students, promoting the idea that self-defense goes beyond physical skills to include financial security and asset protection.
Married since 2018, Duke enjoys golfing in his free time.
Lending a hand in my community.
As part of Northwestern Mutual, I'm proud to help accelerate the search for better childhood cancer treatments while supporting families undergoing treatment, and survivors from late effects. Here are some of the organizations we partner with:
Alex's Lemonade Stand Foundation for Childhood Cancer (ALSF)
ALSF funds cancer research, raises awareness, and supports the families of children with cancer. Since 2012, Northwestern Mutual, its employees, and financial professionals like me have donated more than $20 million to support ALSF and fund over 400,000 research hours.
Beads of Courage
Beads of Courage is an art-in-medicine program that helps kids with cancer tell their unique treatment story through colorful beads that are symbols of their courage.
How Northwestern Mutual helps you live the life you want.
When people feel better about their money, good things happen—they become more confident and feel more secure. For more than 160 years, Northwestern Mutual has helped people achieve the financial flexibility they need to live more and worry less.
Being a mutual company means Northwestern Mutual reports to its clients, not Wall Street. They don't believe in chasing fads or taking undue risk for short-term gains. Instead, they take a long-term approach—both in the way we help people plan to reach their goals, and in the way they do business. This has served their clients (and mine) well through all kinds of economic ups and downs, including wars, recessions, even the recent pandemic.
It's why I'm happy to be part of a company that's in it for the long-haul and prioritizes clients over profit.
