I am very sorry for your loss. I briefly know Charles Amberg; however, I work with his son, Howie. Howie is one of my best friends and is the hardest working person I know. In meeting Charles a couple times; I know why Howie is such a great person. I am grateful to know someone like Howie and have a chance to meet the person that raised him. I am very sorry for your loss and my family and I are thinking about you.
