Karl Robert Kuelthau

Downers Grove, IL - Karl Robert Kuelthau, age 47, of Downers Grove, IL, formerly of Brookfield, WI, died unexpectedly July 18, 2020. Karl was the beloved husband of Tiffany Kuelthau and loving father to his daughter, Taylor (15) and son, Jack (14). Karl is also survived by his parents, Bob and Kathy Kuelthau, his sister Kristin (Bob) Paulsen and numerous aunts, uncles, cousins, nieces and a nephew. Karl was born August 21, 1972 in Milwaukee, WI, and graduated from Brookfield East High School in 1990. He attended Lawrence University in Appleton, WI and graduated with an Economics degree in 1994. Karl continued his education at Marquette University in Milwaukee, WI, earning his Juris Doctorate in 1997 and his MBA in 1998. Karl was an accomplished financial professional, obtaining both his CFA (Certified Financial Analyst) and CLU (Certified Life Underwriter) certifications and was a registered securities broker. After beginning his career in valuations at KPMG and Investment Banking at DN Partners, Karl shifted his focus to what he loved and did naturally - helping people. First at Northwestern Mutual, then at Googins Advisors, Karl advised and guided families through financial and life planning decisions, so they could live their fullest lives and achieve all of their family's dreams. His calm nature, sincerity and level head instilled confidence in his clients. He particularly loved working alongside his Aunt Louise during the last 5 1/2 years and was looking forward to assuming the role of President and Owner in the very near future. Karl was a devoted husband and father, and family was the most important part of his life. He enjoyed snow skiing, water skiing, biking, tennis and reading. He had a thirst for knowledge, a caring and sincere demeanor, always a friendly smile, an exceptional sense of humor and quick wit - loving to laugh and have fun. Karl walked through this life with a heart of gold and a happy soul. He will be deeply missed by his family, friends and all who knew him. A private family memorial was held in Eagle River, WI and a celebration of Karl's life will be held in Downers Grove, IL at a later date. For information www.toonfuneralhome.com OR 630-968-0408

I am so saddened to hear of Karl's passing. I can hardly believe it since we just had talked on the phone for about an hour just a few weeks ago, as we would typically do a few times every year. Karl has been a great friend for over 20 years and I will remember him for his kind, caring, and thoughtful manner as well as his sharp and funny wit. Our thoughts and prayers go out to Tiffany, Taylor, Jack, and his entire family.
With love,

Dear Kuelthau Family -

We could not be more saddened by the news of Karl's passing. Truly.

His gentle thoughtfulness came through in every interaction. An innate interest to positively reference his family speaks further to his character and priorities. We will miss him greatly and appreciate the time we were able to spend in his company.

We will think of you all often and pray for as much peace as is possible during this time.

I worked for Karl at Northwestern Mutual. He was great fun! He was a great boss and a great friend. We had lots of laughs at the office and got a lot done. I will always remember being in his office on the 46th Floor of 1 North Wacker just enjoying the view. He’d let me stay as long as I wanted. Gazing out the windows. Karl was a great man. A great boss and a great friend. My heart is heavy for his loss. I wish Tiffany and his children the best of healing.

I am very saddened by Karl’s passing, my very sincerest sympathies to his wife and children. I was a client of Karl’s and became a client because at my first meeting I could see he was both knowledgeable and a great human being. His passing is a great loss. Mat God hold Karl in his hand.

I met Karl when I was 6 years old, it didn't take but a blink of an eye to become friends. We were lucky to be able to go to Brookfield East high school together. All I have are great memories of Karl being a really down to earth kind person. My sincerest condolences to Karl’s wife, children, the rest of his family and closest friends.

Karl had a way of making people feel they were important to him. That is a special gift. He also always felt to me like he was enjoying the ride through life which made him fun to be around. While I'm glad he didn't have to suffer (much?) I imagine his sudden death must be quite a shock to those close to him, most especially because he was so present and engaged. Be gentle with yourselves.

Karl was one of those rare guys who nobody ever said a negative thing about. He had a calm disposition, a quiet confidence, and a sly sense of humor. He and I are the same age - we met and hung out in the city after college, got married around the same time, and had kids around the same time. We had many conversations about raising a family (including just a few weeks ago), as it was his favorite thing to talk about. He will be missed.

Tiffany, Taylor and Jack, my heart aches for you all and I am sending lots of love and peace your way. Karl was an awesome person and I will miss seeing him around the neighborhood walking the dog. I've known him since his days at Northwestern Mutual where we were colleagues and always loved running into him in our little DG neighborhood. My family sends our sincerest condolences to you, your family and friends who are grieving this tragic loss.

Karl was a true gentleman and professional. I enjoyed the time we spent together at NM, particularly the times we drove together to Lake Geneva. Fortunately we got to see each other again recently during flag football in Downers Grove. I was incredibly sad to hear of his passing. May God give you and your family peace and comfort in the days ahead.
