Kathy, received your nice note to Barb and I! I'm pleased you gave the flowers with the flag to your granddaughter and her Army Husband. You and Gary were a couple of my early clients and I always enjoyed Gary's practical outlook on life and family! He was a good guy that was taken too soon.
Love and God Bless to you and all your Family!

Remember all the times Gary did so much for other people - loaning a vehicle, building a ramp - good man and blessing to so many as he was blessed by God - you will see him again. Our prayers and thoughts are with you.

Dear Kathy,

Please know we are praying that the Lord would bless you with peace in your heart at the loss of your dear husband, Gary. Mom and Dad always enjoyed your friendship at Holy Cross through the years, and Mom often spoke of something the two of you had talked about or done together at church. Even though we haven't seen each other in years, I remember with joy our high school friendship. We are praising God with you for Gary's new life with our Savior, Jesus. With love, Stu and Alice Brassie

We're very to hear that Gary has passed. I had worked with Gary for many years at Caterpillar and always loved visiting with him about scouts and working to get things set up for our customers in the field. We did a video years ago to tell the dealers how to repair bonded windows in the field and Gary helped coach me through the filming and was always a great friend. Please know that Gary and your family will be in our thoughts and prayers. God bless you all.

Our sincere condolences to the family of Gary Knapp. I remember Gary from the early days when he worked part-time at my uncle's hardware store on Starr Street in Peoria. Gary also attended Peoria Spalding, although he was a few years behind me. I also remember the Knapp family from my early days at St, Boniface on Louisa Street. Gary was a fine young man. May he rest in the peace of the Lord.

Our prayers and sympathy to you Kathy and all the family. We pray that our Lord Jesus Christ will bring His peace to all of you . Cherish the good memories and know we will all see him again when we see Jesus Christ face to face as he just has. "He is our peace." Eph 2:14
