In conversation

What do you think makes MML stand out?

The flexibility of our approach. MML’s ability to tailor our investments and structure to fit a company’s needs is differentiated in mid-market private equity and allows us to truly partner with management teams. Every company is different and faces its own set of unique opportunities and challenges, so our approach is designed to help companies reach their full potential across a wide range of situations.

Is there a deal that stands out in your mind as your proudest investment?

This is a difficult question because I’m proud of many of my deals and most importantly the relationships and friendships I developed with the management teams along the way. My proudest investment was a business that was responsible for driving forest sustainability and replenishment in North America. We were responsible for planting over 1.1 billion trees over the course of our ownership.

Name five things you could not live without.

My wife, my dog, my family, my friends, and the beach!


"I have worked with Sean for over a decade. He is the consummate partner. He understands complex businesses quickly, focuses on the most important strategic business points without missing the finer details and continually generates new and creative solutions to difficult challenges faced by all types of businesses. I have seen him work particularly well with founders and closely held businesses because of his ability to balance the viewpoints of many different stakeholders and drive consensus among them."
