About Us

Closing deals & opening doors since 2002

Selling or buying a business can be an exhilarating life milestone—but it can also be fraught with confusion, stress, and overwhelm. Since 2002, we’ve put 100+ years of M&A experience to work for countless privately-held businesses to help them reach their goals.

Combining our proprietary process and intimate understanding of both the financial and human side of each transaction, we’re here to guide you through the exhilarating, sometimes nerve-wracking, always life-altering journey that is buying, selling, or recapitalizing your business.

Our Philosophy

M&A—the Calder Way

Our mission: to provide privately-held companies with the same level of sophisticated, custom M&A services often reserved for Fortune 100 companies. Here’s how we do it.


Decades of successful dealmaking inform our every move and word

With several decades of dealmaking under our belts, we know how to get deals to the finish line. Our team’s diverse professional and practical experiences—including owning businesses of their own—has taught us how to navigate not only the transactional aspects of a deal, but the human side, as well.


Truth-tellers to the core, radical transparency runs in our blood

Our clients know and love us for our tell-it-like-it-is style. Like you, we care deeply about integrity and stand firmly by our commitments. We’ll work hard to understand your needs and goals. We only represent clients that we’re confident we can help and who are committed to seeing the process through.


We vastly over-perform the market; the proof’s in the pudding

Our singular focus on helping our clients achieve their dreams has led to an impressive track record. Our clients’ success stories speak for themselves. So do our numbers. 85% of the businesses we represent sell within 12 months, compared to only 15-20% of those listed with brokers.

“Working with Calder has been the gift that keeps on giving…

They made sure we not only got the absolute best investor for our business—who has opened so many doors for us, who we gel with and have a blast working with—but that we structured the earnings and the payout in a way that benefits us into the future.

Plus, our employees are so excited to be part of a company worthy of someone who wants to invest in us, who believes in us. We are so grateful for the outcome of this deal. It’s a testament to the hard work and dedication of Cress and the entire Calder team.”

Ken Kelly, Kelly Roofing, LLC

“The folks at Calder are true partners — but more importantly, true friends.”

“I hired Calder because, quite simply, they’re the best out there. They paid attention to the smallest of details, not just in regards to my business, but to my personality and long-term goals, to help me find the best fit buyer. I consider them as true partners—but more importantly, as true friends. I’d work with them again in a heartbeat.”
