Kathy and family: Terry and I started kindergarten together in Merrill and we remained good friends throughout our lives. Although we did not see much of each other the last several years, I have many great memories of Terry. He was a very kind person and I know all of you will miss him. Treasure all the good times.

Kathy and family: So sorry to hear of Terry's passing. He was a special cousin with a special spririt. Many great childhood and late teen memories. As 4-5 year old cowboys , he was always Gene Autrey and I was Roy Rogers. We caught fish from Mink creek, played little league baseball(Terry had a wicked curve), and made trips to North Sioux for a brew or two. I remember him as a deep thinker and just plain a darn good guy. May The Lord bless you in the upcoming difficult but joyous times. Barry Jessen and family
