  1. Very sad about the bad news and its circumstances.

    May I express my condolences to the family.

    He was a great collaborator for the Standard Plant and for other activities.

  2. To Donna and family,

    I worked with Mark for many years at GE. Even though I worked in Schenectady, we were in constant contact. I interviewed Mark for the job at GE and despite my efforts to convince him to run away as fast as he could, he chose to accept the position. His decision was from that day on a huge benefit to the company and to me personally. We worked closely on many significant issues and I could always depend on Mark to be professional and add the necessary perspective to help get us through the problem. He was a fine engineer as well as a fine man and I was honored that he considered me a friend. Please accept my condolences on your loss. May many warm memories of Mark as a husband and father help you through this difficult time.

  3. To Donna and family,
    Mark was good friend and co-worker for more than four decades. He was always willing to lend a helping hand and give assistance whenever he saw someone struggling with a problem. Those of us who were fortunate enough to get to know Mark outside the workplace environment understand that he exemplified the rare qualities of true integrity and humility in every aspect of his life. I am deeply saddened for the loss to you and your family and pray the God will extend His grace to each of you as you face the challenges of each new day.

  4. To Donna and Family,
    I would like to offer my sincere sympathy. I was fortunate to work with Mark at GE and greatly admired his engineering knowledge and down to earth personality. He always upbeat, easy to get along wit and ready to help wherever needed. Along with his work, Mark participated in our GE volunteer projects at the elementary schools in Atlanta, he jumped in with his expertise and labor to make these a success. He will be sadly missed.

  5. Donna and family,
    I offer my complete sympathy for your loss. I worked with Mark over several great years at GE and on several of his power plant projects with Ebasco. I can say with certainty that Mark is the only engineer that ‘got it right’ every time.

  6. Donna and Family:

    You have my most sincere condolences at this very sad time. I had worked with Mark and his colleagues at GE for most of my 20 years when I was with GZA. I found Mark to be the consummate civil engineer with the wit and friendliness which in combination made his projects a success. Mark was more than just a colleague; he was a true friend. We would share engineering experiences, tell a few stories, and enjoy some laughs. He was just special. Mark will be so missed. But the memory of him will leave a warm feeling in us all for years to come.

  7. May God be with the family in this loss. I worked on many projects with Mark during my years with Ebasco & Raytheon. I was in the Electrical department in the office and on various field assignments. In addition to work, Mark and I had quite a few “talks” about his hopes and dreams for his children. I know he will be missed, but many fond memories remain to comfort those he loved.

  8. Donna, Mark, and Jason

  9. Donna and Family

    I am so sorry for your loss. Even though I havent seen Mark and you very much over the years when he came up to see Raymond and my father before their passing a year ago I got to visit with him for awhile. He hadn’t changed at all over the years. It was great to seen him. I hope you and your family can gather strength from each other at this sad time.

  10. Aunt Donna, Mark, Jason and family,
    Our hearts are breaking at your loss. Uncle Mark was such an amazing, sweet man, and our thoughts and prayers are with you, even though we can’t be there.

We love and miss him, and hold him in our hearts forever as the sweet, fun uncle he was to us. 💕 We are so sorry for your loss and hope you can draw strength from each other during this difficult time.
    Love always from Laura (Davis) Fisk, David and Ryan

  18. Aunt Donna, Mark and Jason

    I’m very saddened to hear the news about Uncle Mark. I will always remember his friendly smile and positive demeanor. He was truly an inspiration to me growing up. I will also remember the joy we had when we went fishing in NH.

    I’m thinking of you and your family at this difficult time.

    With love from Mark, Erica, Jordan and Ben

  19. To Donna and family,
    It is with a heavy heart that I offer you my sincere condolences for your loss. I worked with Mark for several years at GE on power projects. I thought of Mark as more than a colleague; I considered him a friend whom I will remember and miss until we meet again one day. During this sorrowful time, may God comfort and carry you and your family, giving you peace beyond understanding. I will keep you in my prayers.

  20. To Donna and family,
    Please accept my sincere condolences for your loss and may God keep you close in this time of grief. I was privileged to know and work with Mark at GE. He will always be remembered as the true professional, soft spoken, and quick to share his knowledge and experience. I enjoyed a great deal of time in his office learning more about turbine foundations than I could ever use. But mostly we talked about fishing.

  21. Our loving thoughts go out to you and your family during this difficult time. Thinking of all of you.
    Sending love hugs and prayers.

  22. Donna, Mark & Jason,

    Please accept my heartfelt condolences on your loss. It was my privilege to work with Mark in the
    Ebasco/Raytheon Atlanta office for many years. Besides being the consummate Civil engineer, he
    was always thoughtful, caring and considerate of others. Please know that our prayers are with your
    family, as you try to cope to with his passing.

  23. Donna and Family,

    I was saddened to learn of the loss of Mark.

    I knew Mark for forty years, spanning both of his stints at Ebasco Atlanta. He was a fine Civil Engineer and Chief/Manager of Civil Engineering. Not only was he a competent engineer, but he was a go-to guy for me for advice when we were both charged with administrative responsibilities for our respective departments. More than that, he was genuinely good man.

  24. Donna and family, Please accept our heartfelt condolences. Mark was an extra special employee and I enjoyed working with him both in both Norcross and Houston. Our prayers are with you all.

  25. Donna and Family-
    I am very saddened to hear of Mark’s sudden passing. I knew Mark to be a beloved husband and family man, accomplished professional civil engineer, one of my many teachers in the engineering business, and of course, an avid fisherman. He will be deeply missed by his family, and as well by his extended Ebasco, Raytheon, and GE family. I pray that Donna and the children can regain balance in their family, with such a central piece missing.
    I fully expect our Good Lord will have Mark upgrading old civil works, foundations, and structures in Heaven, And I am sure he will also have new and better fish stories to tell Donna, when he waits for her, and later greets her into Heaven. Mark….rest in peace. God Bless.

  26. Donna and Family,
    I had the privilege to be one of Mark’s colleagues at GE in Norcross, GA. It goes without saying that he was a tremendous civil engineer, but he was an even better mentor – always willing to take time to share his knowledge and experiences to those of us coming up the ranks. Mark was one of those guys you wanted on your team because you knew that he’d always do what was necessary to make the project successful. He was dependable, incredibly talented, and even more so, he was a kind, caring man. Please accept my deepest sympathies during your time of loss. My thoughts and prayers are with you all.

  27. Mrs. Donna, Mark, and Jason,
    I am so very sorry and deeply saddened that Mr. Mark was taken from your lives. I think the hardest part of losing someone isn’t having to say goodbye, but rather learning to live without them. Always trying to fill the void, the emptiness that’s left in your heart when they go. Mr Mark leaves a huge void because he was a good man. Ms. Donna, Mark, Jason…you are in my thoughts and prayers.

    Mr. Mark,
    Some of my fondest childhood memories were shared with Jason and your family. To me you were a kind and intelligent man. The memories you leave behind with cement your legacy in the mindset of all who knew you. I sad that you left, but find joy in knowing that you’ll be watching over your family until your together again.

    My deepest condolences,
    Danny Anderson

  28. To the Sousa family I offer my sincerest condolences. I didn’t have the honor of getting a chance to know Mr. Sousa, but I was close friends with Jason in high school. I heard the stories about his engineering skills and helping Jason with some of our school technology projects (bridge building, CO2 cars, CAD). He ignited Jason’s technical spark and some of that rubbed off on me. I work with a bunch of older engineers every day and that ‘go-to-guy’ passion doesn’t change. He’ll sincerely be missed but his legacy lives on.

  29. Mrs. Donna, Mark Jr, and Jason,

    I’m deeply saddened by the news of Mr. Mark. He was an exceptional man with kind soul and always welcomed our family with open arms. My prayers and condolences go out to your family during this difficult time.

  30. Donna and family, so sorry to hear about Mark’s passing. We were so fortunate to spend time with him when you visited Connecticut, a visit we will always remember. May you gain strength from each other at this difficult time.

  31. Mark Jr,
    The Eulogy you provided at the service for your Dad and my friend was absolutely brilliant. It shows he was the same gentleman at home as at work.
    Thank you,
    Doug W.

  32. Dear Donna, Mark, Jr., Jason and families,

    It was SO good to see all of you, albeit under very difficult and sad circumstances. We have always loved and respected Mark with great admiration for his wealth of knowledge. He will forever remain in our hearts as we continue to pray for him and all of you. See you again soon.

    Love, Joe and Ruthie
