To my Dearest Diana- the best friend and business partner anyone could ever have. You have positively touched so many lives and will continue to impact both Family & Friends forever. We will always love you. Your #1 Paul.
Diana will be greatly missed by all of us at Essilor. She always had a smile on her face. Her family and friends are in my thoughts and prayers. May God grant you peace and strength during this very difficult time.
This is so heartbreaking. Diana was my boss for several years and the best mentor for guidance. So glad God saw fit to have us meet and spend time together. You will be missed dearly. Always much love. Thank you Nina
To our dear Diana–thank you for your friendship over the past nearly 6 years while at Essilor. From the moment I met you, I knew you were special. You were so very smart, talented, beautiful, confident, and determined. You accomplished wonderful things over the years, many of which were while you were very personally and courageously fighting a very difficult and painful batter with breast cancer. And you did so in the most graceful of ways. You never wanted anyone to know, and were so private that way. But a few of us knew and felt honored to be by your side through your journey. And every day I prayed for you. You were so very proud of your beautiful daughters, Ashley and Rachel, and of your son-in laws, Andy and Josh. Their futures motivated you towards joy. You loved your Mom, and your brothers, and your nieces and nephews. I will miss you as my cube mate, travel buddy, fellow Vegas and wine-lover, and wonderful friend. We will all miss you at Essilor, Diana. And in typical Diana-fashion, you gave this battle your very best. Rest in peace now knowing you fought the good fight, and that all of us loved you, admired you, and were blessed to have known you as our friend. Much love to you and your family, and until we meet again…forever your friend, Deborah
My heartfelt condolences for your loss. May you be comforted by your cherished memories as you await the fulfillment of God’s promise to be reunited with your loved one. (John 6:40)
