Bea and I send our heart felt sympathy to you and your family for the loss of a loved one. It is never easy to fill such a void. Be comforted in knowing that Don is in the arms of our Lord and Savior and your memories together will live on.
Please accept my heart-felt sympathy at the loss of Don.
You are in our prayers.
Dear Paula, Please accept my most sincere sympathies. Don and I worked together over 30 years ago in New Orleans and have been friends over the years. This happened way too soon. Don was a great guy who will be missed by all. With warm regards, Bob Quitzau
Don was a good friend and colleague at Shell and more recently in a business venture. I am indebted to Don for saving my life six years ago when I suffered a heart attack at work. He will be sorely missed by me and many others.
As freinds of Maureen (Haefner) Tonn for more than 20 years, we would like to extend our sincere condolences to you and family. Although we never had the honor to meet Don, we have often heard you speak of him and how justifiably proud you were of him. Our hearts go out to you and Don's family at this most difficult time. Love, Eileen & Dan.
Don and I came to work for Shell New Orleans at the same time in 1977, right out of college.   We roomed together for the first leg of our training in Houston and had a great time.   Don was a great guy and a creative geophysicist.  My prayers go out to his family.
