Aaron A. Umbach, of Saint Charles, MO, passed away Saturday, August 1, 2020 at the age of 59. Loving husband of Elizabeth "Betty" Lee Umbach; beloved son of the late Gerald and Esther Umbach; devoted father of Joseph (Meghan) Umbach and Katherine Umbach; dear brother of Brian B. Umbach.

Aaron worked at General Motors and dedicated over 35 years of service. He enjoyed working outside and took great pride in caring for his home, cars and especially his lawn even winning “Best Lawn” in his old neighborhood. Aaron loved watching sports and always attended his children’s sporting events. Aaron’s greatest love was spending time with his family. They enjoyed family vacations, going for regular walks in the park, and he never missed an opportunity to play with his grandpuppy, Sierra. Aaron was dearly loved and will be greatly missed by all who knew him.

Memorials may be made in Aaron's name to Zion Lutheran Church, Harvester or St. Charles Lutheran High School.

    candle 8What a dear, sweet family man. What great times we shared back in the day-camping, growing into adults . Perfectionism in everything he did from loving his beautiful wife and raising his awesome children . The heavens are brighter by one more star.

    I can’t remember a time that I would pass Aaron in the aisleway of General Motors and he would not say hello or not hello to me just a super friendly guy. I am totally blown away by this, I had no idea.

    His family has all of my sympathy. So sorry.

    I am so sorry and shocked… I was his TL in material department at GM. Aaron was one of the nicest men… always helping and polite. Saw him at Target on mid rivers mall drive a few weeks ago… pleasant as always. He was a good guy and will be missed.

    candle 8You are my shadow, my friend, and yet I had no idea that you were ill. A constant, a humbled man, a hard worker, a dedicated simple quiet reserved man, a family man, a person with pride, who never worked overtime so you could spend more time with your grandkids…. . This breaks my ❤. I know how much you loved your wife and family. What a great guy!!!!! Tuggers will never look the same!

    My sympathies to you and your family at the passing of Aaron. My brother Jim informed me today. Immediately all the memories came flooding back of the cruising in his Duster, float trips, parking lot gatherings etc. Great memories to say the least.

    In my thoughts and prayers at this difficult time.

    candle 7Sending all of you hugs and prayers. Aaron was a gentle giant who had the best comebacks. I have many fond memories including our Harvest Brown Court block parties — who would have thought Aaron could square dance. Your family is a strong closely-knit group and you will get through this, but please lean on your friends for support. We love you!

      My prayers are with the Umbach family. I’m so sorry and shocked to hear of Aaron’s passing.
      I got to know Aaron when he delivered parts to my team in trim at &GM. Later, as we both worked in the material department, he was always ready with a smile and a kind word.
      He will be missed by many.

    candle 7My condolences to the Umbach family, I am so very sorry to read this news. Betty was my classmate at St. Mary’s Academy. While I haven’t seen her for a while, just from her Facebook posts, it was easy to see how much she adores her family. My heart goes out to her and her children in losing Aaron. My prayers are with all of you.

    We are shocked and saddened to hear about Aaron. We were blessed to have such a great neighbor. He and Steve recently had a great talk in the backyard. He told Steve how proud he was of Joe and Katie and how excited he was to become a grandpa. The backyard will never be the same. Our thoughts and prayers are with you at this time.

    candle 3I am so sorry to hear Aaron has passed away. I was so happy when Aaron and Betty started dating. They were made for each other from the start. After high school we had a big group of friends that hung out together for many years, playing softball, going on float trips and many other activities. Aaron was always the sensible one making good decisions while some of us did not. I still think of those days from time to time. “The good old days”

    candle 7Betty, my deepest sympathies to you and all your family. While I never met Aaron, I feel like through your stories at the office, I knew a bit about him. You are in my prayers.

    candle 7Aaron will be greatly missed by his GM co-workers. I had the privileged of working with Aaron for the past 6 years and he was always consistent and calm, even when all else was chaotic. Aaron loved his family deeply and I enjoyed seeing pictures of his wonderful life away from work. Is was a shock to hear of his passing, but a blessing that he went peacefully in his sleep. God bless and keep Aaron until we are able to meet again.

    Will miss Aaron in the mornings. We always passed in the p aisle honking our horns in passing . He will be truly missed by many of us that are still working . I will also miss him coming back to my area and talking on the phone or checking the weather out.
