I did not know Dan well, I worked with Dan on several occasions at Regeneron. In our short conversations together, you could not find a more genuine, friendly and helpful person, he simply was just a “good guy”. I am close to the same location in life as Dan, our children grow up so quickly, one minute they are toddlers and the next they are making their own way in life. It appears that Dan has raised some wonderful, articulate kids and his legacy will go on through you. My sincerest condolences to all of Dan's family.
