Collin L. Pfeiler

Collin L. Pfeiler, age 60, of Dubuque, IA, completed his earthly journey suddenly on Dec. 23, 2021, at Mercy Hospital, in the loving arms of his wife.  To honor Collin’s life, a private family service will be held at a later date.  The Tri-State Cremation Center is humbly serving Collin’s family.


Collin was born on March 23, 1961, in Dubuque, IA, a son to Ronald and Margaret Pfeiler.  Collin was blessed to have been able to grow up in some of the best days around to be a youth and was a proud graduate of Dubuque Hempstead, Class of ’79.  He always had a zest for life and made sure to enjoy the simple pleasures in life when the work at hand was completed.  He spent many of his working years with Hy-Vee, primarily in the meat department, but he did venture out to man the gas station for some time.  Collin enjoyed his years there and made many lasting friendships along the way.  When he wasn’t taking care of his responsibilities at work, you could usually find Collin enjoying the outdoors whenever possible.  He thoroughly enjoyed life on the farm, tending to the gardens, or grabbing a fishing pole and heading to the water’s edge if time allowed.  Collin was also known to set aside a little time for a round of golf, making a perfect campfire for everyone to enjoy, and going to the bowling alley with family and friends only to top off their time together if his Cubs were playing on the tv overhead as well.  Collin’s heart was as big as his personality and his love for others, especially his dog, Asterid, were continually on display.  Collin has faced many health issues over the years and always fought each and every one with all that he had.  His courage and determination were an inspiration to all who knew and loved him.  We will miss Collin more than he could ever know, and are forever grateful for the memories he leaves behind to help heal our broken hearts.  Christmas will never be the same without his joyful spirit filling the room around us, but we trust that he is at peace now from all of his earthly struggles and only awaits our eventual arrival where we will all be reunited once again.  Thank you, Collin, for always taking the time to show us that each day is a gift, and may your legacy live on in the hearts and minds of every life that you touch along the way.

    I had the pleasure of meeting Collin at Tri State Dialysis. He was always a guy who would make us laugh and also one who showed great love for his family as he talked about them often. May he be at peace now and my deepest condolences for his family and friends as he will be definitely missed by so many.

    Peg, Stacy, and Russ,
    My heart breaks for all of you during this very difficult time. Collin was simply one of the best buddies that I could have when we were growing up. He always had my back, and I considered him as close as my own brother. He had a HUGE heart, and he will always be a cherished part of my youth. My condolences to you all.

    Dear Pfeiler family, our heartfelt sympathy from the McDonough family. Collin and your entire family were SO good to us growing up on Asbury Ct. I agree with him, that we were kids at the best of times in the best of places. So many days spent watching (and arguing over) the Cubs games and playing baseball, football, and whatever. “Slim” was like a big brother to all of us, and his kind spirit will never be forgotten! Life on earth is so short. We’ll see him again in “the blink of an eye”!

  10. Glenn and Lin Recker says:

    Peggy, Russ, Stacy and families. We are deeply saddened to hear of the loss of Collin and will be keeping all of you in our thoughts and prayers. May all your special memories give you comfort and peace.
