    You were a wonderful person helping to answer IT questions, along with building and updating people’s PCs. Your boys loved sharing all the great trout and other fishing trips with you. We promise to continue loving, taking to and taking care of your boys and family until we meet again in heaven. Thank you for the memories ❤️

    Mike was our IT guru guy at BJC RCM, and we are so sad to hear of your family’s loss. All of us Admins in RCM were so happy for his well deserved retirement, although a huge loss for us to lose an IT guy that not only knew his craft inside & out, but was always kind & would do anything to help anyone, no matter how busy…it’s a rarity these days to find someone like that. May his family & friends know that he was not only loved in his personal life, but loved & respected at work as well by so many. He was one of the most hard working guys we knew in IT. We are saddened to hear he didn’t get to truly enjoy retirement for long, but knowing him I’m sure he made the best of each day and enjoyed every moment. Something we all could learn from him, is enjoy life, each & every second. It’s too darn short not to. Many thoughts & prayers are with your family during this difficult time. ~ RCM Admins

    Mike was an amazing and helpful guy that everyone at BJC would go to with any IT issues. He was always so helpful and did everything he could to resolve any issues brought to him. He was definitely missed once he retired but I am so happy he was able to enjoy his short time in retirement doing what he loved. Thank you to his family and friends for letting Mike share his time with our BJC family so that we got to see what an outstanding person he was. My prayers and condolences are with Mike’s family and friends.

    I worked with Mike(Mikee) at Titan, best IT guy there was, he would do whatever it took to get the job done. He was the absolute greatest! Great guy all around and will be missed by many. RIP my friend.

  15. Patty Bassman (nee Isenmann) on September 14, 2023 at 8:01 pm

    How can I put into a comment everything I want you to know when I could write a book and still not say everything. You were my protector, my role model and my best friend for most of my life. You had all the qualities of a wonderful human being. You were kind, gentle, caring, hardworking, loving and very family oriented. Everything I could want in a big brother. I wanted to be able to take Carter fishing with you so you could teach him the joys of fishing and enjoying family. I miss you and Ray terribly already! I hope the two of you have found the best spot for fishing and will be ready to go with you both when we meet again! You are both forever in my heart and I love you more than I can say. Give everyone a kiss up there!

  16. Eileen Schumacher on September 14, 2023 at 8:09 pm

    Our Mike (Mikey) at BDS/Titan was the best IT person anyone could ask for. He was a best friend to me and had a wonderful soul. He took care of all of us without complaining. We shared a lot and became very close. I wished him the best when he moved on to BJC, and he made many new friends there as well. He was a personable person and I am blessed he was a part of my life

  17. Kris Thompson on September 14, 2023 at 9:27 pm

    I knew Mike from BDS/Titan company. He was truly a very caring person and went way above and beyond for an IT employee. He did every other job that no one else had time to do. He was very smart and was funny! So sad he went so early.
    Praying for the family.

  18. David Phelps on September 15, 2023 at 8:34 am

    I was able to chat with Mike while visiting my parents this past June. He was walking his dog. We caught up after many neighborhood years have passed. He was looking forward to his retirement and fishing. Saddened to hear of his passing. Prayers for the family.

  21. Deb Stein on September 17, 2023 at 8:26 am

    My dear friend words cannot even begin to describe the profound loss I feel. You will be so missed. Prayers to all.

    Penny, I never really got to know Mike, but I’ve known you for over 55 years, and we are sort of related. I always knew that Mike was the best thing that ever happened to you. I understand your loss so deeply. Please keep in touch.
