I worked closely with Don for his last 6 years at Nalco. He was always a friend to everyone he met, approached everything with positivity, and was a very ethical man. He was full of great stories that were shared over lunch or a car ride. Don will be greatly missed. I will keep keep Don's family in my thoughts.

I worked with Don for many years and shared many conversations over lunch with him that would include a wide range of topics. I always loved hearing the story of him playing in a high school football state championship game and other stories of working in the water chemistry industry. Don was such an awesome person that taught me so much about water chemistry and life. Such heartbreaking news to hear about this!!

I am so sorry for your loss. I enjoyed very much working with Don at Nalco. He was not only a mentor but a dear friend. The last couple of years Don and I worked together we spent a lot of time traveling to accounts and working closely together. We had many conversations about life and his adventures throughout his career. The two subjects that would always come up were his family and the time he spent in college at the beach. In Corpus Cristi I think... My family and I will keep Don´s family in our prayers! I am grateful I had the opportunity to get to know Don and the time him and I spent together.

Don was a terrific man - one that I was proud and grateful to have as my friend. We worked together for many years at Nalco. I will miss him greatly. RIP buddy - for a while. Then get with God and make sure all the water treatment systems in Heaven are working the way that only you could make them work. My sincere condolences to Patty, Gracie, Whitney and Andrew. Don loved all of you so very much.

I was Dons coworker with Nalco in the 1990s and 2000s. I remember his love for his daughter and wife. I recall he was an involved soccer dad. I heard the sad news thru a mutual friend. RIP Don and peaceful thoughts to his family.
