Then, to actually experience the results of these grants was a huge bonus!

The pure joy exhibited by those players touched everyone participating in the games, including the players, their families and all the volunteers.
What Makes GPD Different:
The difference is the commitment of the firm to actually put into practice their core values. They aren’t just statements displayed on a plaque somewhere, they are action items that we all believe and practice.

Funniest Moment at GPD:
While it was funnier for others than some, a couple of people sent a co-op to the field across the street to look for a nonexistent manhole.
