James Macon Patton

Bob (and Susan) were wonderful friends to my parents through the firm and that friendship evolved into a wonderful friendship outside of the firm. I will cherish my memories of our friendship. Thanks Bob for helping me understand how important it is to maintain a healthy lifestyle.

I had the pleasure of working with Bob for many years at Patton Boggs. Bob was the consummate gentlemen, respected for his excellent judgment and strong legal skills. He was friend who cared about his colleagues. He served as a mentor for many government contracts lawyers. As much as Bob was devoted to work, it was always clear that Susan was his true love. I enjoyed the time that Bob and Susan and Ellen and I spent together. I am glad that he made it to Florida for the last few years of his life even though we missed him at our informal PB alumni lunches. Susan: I am so sorry about your loss. You have lost an outstanding husband and a very special guy.

Dear Susan, so sorry to hear about your loss. Bob was a true gentleman and a principled human being. He was a great mentor to me when I first became a lawyer. I always valued his counsel.

I met Bob at PB in 1985 and had only the highest respect for him. I worked directly under him from 1999 to 2010 as his Office Manager and really enjoyed working with him from day in and out. He always spoke so highly of his wife, Susan, and of his family. You and your family will continue to be in my thoughts and prayers. Bob, you continue your passion of running those marathons in heaven and I will be cheering you on! All my love dear friend.
