Dear Jennifer, Tommy, Chris and Samantha,
How sorry we were to learn of your dad's passing. He was charming and humorous and a wonderful friend. Although, sadly, we lost touch over the years, we have thought of your family often and would love to hear from you. You are in our thoughts and prayers.

Our sincerest sympathies.

Terry and my deepest sympathies Susan on the passing of your wonderfully intelligent and clever husband, Tom, whom I met while we worked together and travelled with Dr. Robert Maurer on our Environmental Negotiations seminar for the Navy. Tom was a delightful colleague and friend and the two of you made such a magnetic couple, and both Terry and I have fine memories of the time we spent together. Tom's big heart, intellect and sense of fun will always be remembered very, very fondly.

My condolences to the family, and deep gratitude to Tom. He was generous with his time, insightful with his advice, and lighthearted in company. Unlike many established professionals, Tom did not neglect people who were starting their careers (as I was when we first met). I will always appreciate that. Rest in peace, Tom.

Tom and I worked together in the 70s and 80s. I worked for the US Conference of Mayors' Labor-Management Relations Service. He helped us develop and deliver training programs for state and local government executives. I view Tom as one of my most significant mentors. A true professional.

I am so sorry, Susan. I barely knew Tom other than knowing that he was a giant in the field, a pioneer, and a man who shared his knowledge with hundreds of others. The world is a better place for his life.

Dear Jennifer, Tommy, Chris and Samantha,
I am sorry to hear of the death of your father. I spent many happy hours at the home in Bethesda and working with your father doing dispute resolution. He was fun to be around and helped me build the Science Room in the Bannockburn Nursery School with Wayne and Mario Tama. So many memories. Aaron and Justin send their condolences as well.

Tom was a 'special' friend. He was 'unique', his friendship unconditional. It was my privilege to be part of his journey. Sincere condolences to Susan and family
