Welcome to the 2017 Power 50 list, which ranks the most influential people in the industry.

#8: Greg Muzzillo & Vera Muzzillo, Proforma (asi/300094)

2016 Rank: 5

The husband-and-wife team slide in this year’s rankings after receiving lower peer ratings and following a rare decline in annual sales in 2016. The fall will likely be short-lived, though, as new owner sales are trending higher at Proforma, boosted by a growing suite of service tools.
