I worked with Dave for many years. He was my first TA at Unit 5 and taught be the value of integrity and humbleness. He was a good man who respected everyone around him and gained respect from all. I know the loss of him will be great to his family. I am so sorry and pray for you all in this difficult time, but I'm glad I was able to be part of his life. He will make an everlasting impact on my life.
