A 30-second interview with...

If you could share a cross country road trip with someone famous (alive or dead), who would it be and what you would discuss/do to pass time?
I would love to go with my father when he was 40 so we could hang as peers and discuss our commonalities.

What is the best professional advice someone ever gave you and you still live by?
Make the decisions that are in the best interest of the people, the clients and the culture.

How did you get your foot in the door?
I was an engineering major and took a job in Philadelphia to be close to my wife. I wasn’t looking to stay there so I interviewed in NJ. This resulted in the best interview of my life at Wiss with Ed O’Connell.
