It is with a heavy heart that I just learned of Dan´s passing. My most sincere and deepest condolences to Terry and the O´Brien family. I had the privilege, honor and pleasure to work for Dan for 15 years at Grumman in Personnel Dept. Not only was Dan a remarkable mentor to so many of we young people just beginning our way in business he was also a great friend. He had a dynamic personality, a great sense of humor (and smile) and huge compassionate heart and soul. I loved all the spontaneous visits he made to come see me when he came out my way. I think he was checking on "his deck". He left an indelible and everlasting mark on my heart and life. I was blessed to have known and loved him. Rest In Peace Mr. O´Brien, Dan - "Because My Daddy Said So"
