Everyone’s a good partner when things are going well, but you get to know who’s really a good partner when things aren’t going so well. I’ve seen Clairvest behave during good times and bad times, and they’ve always been more than fair. Even when they could have taken advantage of situations, they never have; they’ve always been fair. I think that’s why we went back to them [with County Waste]. It’s all about picking the right partner.
Jerry Cifor
Board Member, County Waste of Virginia
My family and I have partnered with Clairvest across three separate waste management platform investments – there is no better way to demonstrate the trust we have in them as an equity partner. During the good times and the difficult times, Clairvest has always been constructive and acted with integrity. I have had the pleasure to work closely with Ken Rotman, Michael Castellarin, Doug Horn and the Clairvest team and their passion for helping partners like Winters Bros. grow in the waste management industry stands out. Clairvest is not just money, they are our partner of choice.
Jimmy Winters
CEO, Winters Bros. Waste Systems of Long Island
I decided to partner with Clairvest for the second time because of their unique and collaborative approach to investing. They are true partners and fit well with my management style. They were very helpful and supportive as we grew County Waste of Virginia aggressively over the seven-years, providing capital, as well as resources and analysis to help make better decisions.
Scott Earl
CEO, County Waste of Virginia
