“It’s been great to work with the Calder team. Logan is unmatched in his tenacity for bringing us qualified leads. He balances persistence and professionalism throughout the process. In many instances, he’s the first touch point of our firm’s brand with prospective future partners, and he does a good job representing us. And, Jon has been a reliable thought-partner for us as we evaluated dozens of opportunities. In addition to finding qualified leads, Calder helped us establish informed valuations and offer letters, helped negotiate many of the details that must be addressed in a deal, and even helped us say ‘no’ to deals that weren’t right for us.”
– Jonathan Reinemund, Managing Partner, Highline Group, Denver, CO (Buyer)
“Working with Calder was a top-notch experience. Jon and Logan spent countless hours with our team, coordinating this deal and seeing it through to the finish line. The Calder team took the time to guide us through diligence, ensuring a clear understanding of this complex process.”– Nick Preece, Founder, Preece Machining & Assembly, Boulder, CO (Seller)
