What do you like about living in the Pacific Northwest?

The Puget Sound on the West and the Mountains on the East. We have the best football fans in the world.

Why do you work here (at the District)?

I get to work in an innovative environment.  I get to see facilities I personally designed built and functioning in the real world many, many times each year.

Bonus fact!

  • I used to be a competitive swing dancer.
