It was surreal being at John’s funeral today. It is still not believable that he’s gone. We met Rita & John via Fort Collins Newcomers in 2011. We became fast friends over the years and had have dinner often. John and Don would also together together frequently.
John was a fully honest man and yet a complex man. We will miss him terribly. Rita, we are here for you. God Bless. Nancy & Don

I first met John on a road trip after marrying his niece, Trish. We drove from Texas to New York and visited he & Rita in St. Louis. John loved to engage with people. On our first day there in St Louis he wanted to know all about me. A very welcoming guy. We hung out a lot during that short weekend and formed a great connection.

I enjoyed John's company at many family gatherings through the years. He was always interested on how life was unfolding for me and I would inquire into his life also. He was a wonderful human being, the world needs more like him.

My heart goes out to Rita, Susan and John Jr. You will all miss the husband, father and friend that he was. I'm sure he is experiencing freedom from the health issues that challenged him, and he misses you all as you miss him. Love to you all.

I have known Uncle John my entire 31 years. He, aunt Rita and my parents were best friends. They did life together and I am thankful he was such a huge part of mine. From dinners, spending every Super Bowl together, throwing a squishy tomato ball at each other non stop for years, going to the Sweet 16 together and basically just showing up for everything... he was always there. My husband and I got to go on a hike with him about 4 years ago and he definitely out-hiked the both of us. My husband talked about how awesome Uncle John was and how impressed he was with him the entire trip back to Dallas.
I will miss “Unca John” greatly, but am forever grateful he was such a big part of my life.

We have known John and Rita most of our lives (Rita and Pat since first grade). Curt and John have bonded over craft beer, wine, tennis, golf and lots of conversations. After many years in St. Louis, we both moved to different states. We continued to visit each other in our respective homes or meet in fun cities to vacation. Our daughter, Katie, grew up loving her "fun Uncle John". We have so many memories of their times together.
We will miss John's humor, thoughtfulness, compassion and winning smile.
Our deepest sympathy to Rita, Susan and Johnny.
Rest in Peace dear friend, until we meet again.
With love,
Pat and Curt

My wife & met John & Rita on a recent vacation to the U.K. We immediately knew they were special people and besides exchanging e-mails, we exchanged visits to each other’s homes.
John had that special knack of pointing us to the best pub with the best happy hour and food. His amazing humor and fun loving spirit have left us but we are endeared with his memories.
Such as: we walked into a small pub in York, England after extensive shopping with the wives. The bartender asked John what would the ladies like to drink. John replied “Well, I don’t know, we just met them”.
We had plans to visit with them again, but illness and injuries kept it from happening.
To Rita and family:
We mingle sincerely our tears with yours. We are so blessed to have known John. He was so full of life and enjoyment!
With all our love,
Rick, Deena, & Derek Graham

I met John and Rita through their daughter Susan. They were still living in St. Louis at the time. When we got together there was usually food and wine involved and lots of laughter. John was a kind, gentle soul who will be sorely missed.

If I had to describe one of John’s passions, it would be that he loved the outdoors. He loved being in it. He loved looking at it. He loved traveling to see it. He enjoyed seeing things that “were bigger or more beautiful than could be described”. He once told me he spent much of his life exorcising so that he could be fit enough to do just that. John spent the last part of his life living where this was possible. Now he is in a position to make the greatest journey that man can travel, to see and do that which can’t be described. We will follow you John so we can talk again, and drink a beer, if they have it there!

Met John and Rita through the Fort Collins Newcomers Club several years ago. We remember having a lot of fun with both John and Rita at club wine tastings and gatherings. What a wonderful man and great conversationalist! Heartbreaking to hear this news. John will be missed indeed. Hugs to you, Rita.....Donna & Jud

We enjoyed many good times with John. Golfing, hiking, snowshoeing, dinners, happy hours and many good conversations. Libby worked with Rita in St. Louis and Dennis met John on a trip to Sedona in the mid nineties. Sedona was very special to John and Rita, and became one of our favorites, too. He loved the hiking there and was fascinated with the enchantment of the area.
We’ll miss John immensely. We send our thoughts and prayers to Rita, Susan and Johnny.
With love,
Dennis and Libby
