Wendy, Sarah, Olivia, and Abby, you are all in our prayers. We are so sorry to hear of your loss. Sending so many hugs to you all. May your memories keep you strong and bring you comfort in the knowledge of how much he loved you all.

Wendy and family, please accept my deepest condolences. I had the pleasure of working with Dave at Ion Torrent / Life Technologies / Thermo Fisher for many years, beginning with our early days as a startup. He was a wonderful mentor, and certainly had a positive impact on me as a young professional engineer. I learned how to do a lot of things in the lab the right way, influenced by his careful and meticulous nature. He always struck me as someone who wanted to deliver a high level of...

May your hearts soon be filled with wonderful memories of joyful times together as you celebrate a life well lived.

My deepest condolences to the Marran family. I enjoyed a lot working with Dave at Thermo Fisher. Although our interactions were mostly online via WebEx, Dave never failed to show his dedication and truthfulness to work and his colleagues. I always looked forward to his visits at South San Francisco so we could do an in-person, 1-on-1 meeting. He was a caring and thoughtful mentor to me, and he will always have a special place in my heart.

On behalf of the Mercy High School community, we offer our deepest sympathy to our alumnae, Sarah, Olivia, and Abigail, and to all those who loved your dad. Please know that we hold the Marran's and their friends in our thoughts and prayers during this difficult time. We are very sorry for your loss.

Dave and I worked together at On-Line/MKS until 2003. He stood out as one of my favorite coworkers (technically, I think he was my superior, but it never felt that way). Primarily, though, he is one of the nicest people I have ever known. I feel so fortunate to have been friends with Dave. "Creative and caring mentor to all" is no lie. He was a fantastic person.
