The Third Annual LCGC Pittcon Awards: Establishing a Tradition
By David Walsh
They say it takes several years for an awards program to really get off the ground and start amassing a history, establishing a place for itself in the industry. If this is true, then I believe we can safely say that this year, the LCGC Pittcon Awards have officially arrived. With past Lifetime Achievement Award winners such as Walt Jennings and Harold McNair, and bright young stars such as Gert Desmet and Kevin Schug claiming Emerging Leader honors over the past couple of years, there is a great deal of suspense building over who will win the 2010 awards, set to be presented at Pittcon 2010 in Orlando, Florida.
