“Deirdre and I worked together for many years traveling /working for Borden in Pennsauken NJ. We had many great trips together to see the tomato crops in California and Israel. We even rode a camel together. We became very good friends. She visited our home in Wisconsin once and we had lunch with her in Houston at LaMadeline whenever we were in town. I recently tried to contact her but never got a return call. Now I know why. I will always miss her and the love we had for each other as friends.”

Tim ONeill wrote a sympathy message

“Tim O'Neill, Deirdre's brother We appreciate the messages that are coming in from all of Deirdre's friends and co-workers. It really does help with the sense of loss, so thank you. You may not know that she had been suffering terribly recently. Arthritic neuropathy and several other conditions were really taking a toll, and some days she could barely cope with the pain. The prognosis was not very good, either. She is free from all of that now. Her suffering is over and she will rest in peace.”

My prayers are with her family, friends and colleagues as I know her absence is weighing heavy on our hearts and minds. Godspeed Deirdre - you will be sorely missed.”

“This is such sad news. The first time I 'met' Deirdre was in the elevator at work. I'd spoken with her in meetings before, but never in person. I recognized her voice and spitfire personality immediately, and confirmed that it was her. She brought personality with her wherever she was. The world is a little less bright.”
