Brown and Caldwell is a 100% environmental and 100% employee-owned firm with over 1,700 employees all working towards a common goal: to make a positive impact on our environment and in our world. Brown and Caldwell has worked on major biosolids management programs throughout the country.
Ask anyone who works with Billy Lewis to describe him and you will hear quiet, considerate, hard worker and a man of few words. You would think someone who sells biosolids products for a living would be a big talker with a crap load of bravado. That is not the case with Billy; instead, he enjoys the quieter things in life like spending time with his wife and two boxers, running, camping and golfing.
