Ana, I am so, so sorry. I can't even imagine what your're going through. I worked with David on a few projects. He was such a good person. You and your family are in my prayers.

Oh, Ana, my heart is breaking for you and your family. I worked with David briefly during the consent decree. He was a wonderful scientist and a kind man. So very sorry for your loss.

Ana and family,

I was fortunate to know David as both a friend and colleague. He was a generous mentor who helped me grow as a scientist and manager at Abbott. David´s breadth of knowledge was remarkable, and he always had a new insight-or a memorable story-to share over lunch. He spoke with deep pride about his family, and his love as a husband and grandfather was evident in everything he did. I remember the proud day when Tristan, started working at Abbott.

I am grateful for the time we shared and the guidance he offered. My deepest condolences to you, Ana, and to the entire family. May his memory be a blessing.
