John, it was a real pleasure to know you and chat about so many different subjects over the short time we knew you. We will miss you dearly. Our sincere condolences to Teresa, and all of John's family and friends. Sharon and Peter Doyle Mustang Acres neighbors
Teresa, David, Dusty, Ann and all family And friends: Words cannot adequately express my Sadness. My deepest sympathy for your Loss. My life is richer for knowing you John. The World is a warmer, kinder place because of your life. So sorry.
I only had the opportunity to know and work with John for a bit more than a year, but he was definitely a dynamic presence in our organization. He was an enthusiastic contributor, and he will be remembered with fondness. All of John's NCAR colleagues extend our sincere condolences to his family and loved ones. Mark Bradford, NCAR
My thoughts and prayers are with Theresa Jamul and the Clark families. There is no easy way to lose a beloved spouse or sibling. It's especially hard to lose someone so unique as John--full of life, fun, and a passion for the beauty of the earth. Know that you all are in my thoughts and prayers at this sorrowful time. May John rest in peace! Lovingly from your cousin, Betty Ann McNeil, DC
I am so saddened and shocked to hear that John passed away. My condolences go to all of his family. I really enjoyed worked with him at NEON Inc. His antics, stories about chickens and reminders about the importance of security (and what happens when you don't do it) kept us laughing. I have some nice photos of him helping kids at Take Your Child To Work day. As a big kid himself, he was right in his element and the kids loved him. Let me know if you would like them sent your way.
I am heartbroken at the loss of my dear friend. Soon after we met kayaking on the Youghiogheny, we ran into each other on the Potomac, had dinner, and became fast friends. He patiently accompanied me on the Gauley and Cheat, and even called me one morning to (try to) talk me into running Great Falls. His counsel about kayaking after I moved to Michigan was to buy xc skis, another piece of good advice that led to backcountry trips together in Colorado. I always admired his affability with strangers and friends of any age, finding connections, reaching out to others the same way he had to me: friendly and disarming. A second big brother to me, John modeled steps from my early 20s into real adulthood, simultaneously modeling keeping being a kid. I’ll miss you, John, kind loving gentle soul. My heart goes out to Theresa and all of John's family. - David Dickinson (DC & Ann Arbor)
I met John while working as an intern with AAAS in Washington, DC, during the summer of 1986. He was a fun guy to work with and was very kind to me, explaining, among other things, what a computer mouse could do. I can attest to the fact that he loved the outdoors and kayaking. For some reason, I always wondered what became of him, so I googled him to find out. I recognized him immediately by his smile and was surprised that the picture was an obituary. My condolences to your family for your loss. I know you will greatly miss him. Sincerely, Stacey Newton
