What is the one area you are most proud of?

“I enjoy going past structures I have designed over the years and seeing the impact on the community.  From arenas, to schools, to strip malls, to houses, it is really cool to drive by ‘my buildings’, seeing that design become reality.  It has also been rewarding to see both of my kids attend school in buildings I have designed.”   

If you could share one tip with new engineers, what would it be?

“Do your research and ask questions.  Often, I tell young engineers who work with me that one of my goals is to get all of the knowledge in my head that I have accumulated over the years into their head.  By far the best way to do that is for young engineers to ask situational questions and tap into that experience.”
