I'm William Deiss, the Vice President of Member Engagement and Learning, here at NAHB. I've had the privilege of being an NAHB staff member for 20 years where my focus has been membership and education. At my core, I'm a numbers guy who enjoys making projections and dissecting trends. This could explain why I am such a baseball fan, since we count everything in baseball. I still play wood bat hardball from April through September, although like the pros, we took 2020 off.
