What Clients Are Saying About Dunn Rush

I’ve known the Principals of Dunn Rush & Co., for a number of years and have had the opportunity to work with them in many different capacities. They’re true professionals, with deep experience in a wide range of transactions, across several industries. They are good people and I have always enjoyed working with them. You can trust them to provide top-quality advice no matter what your situation or circumstances.

Mark Bono / Founder, Guide Capital Partners

I was approached by multiple potential buyers and knew I needed help to navigate the process while continuing to run my business. Dunn Rush was instrumental in organizing the data room, managing the bidding, facilitating negotiations, maintaining positive communications, maximizing the sale price and getting it over the line. I highly recommend Kevin and Greg.

Bob Keeley / Former Owner & CEO, Diversified Project Management, Inc.

Kevin and Greg helped me work through a very complicated series of simultaneous acquisition opportunities. They lined up and negotiated the necessary equity and debt financings, and worked through all the issues to get the best deal closed iin tough market conditions. They gave me great advice throughout the process and did whatever it took to help me get it done.

Pat Purcell / President & CEO of Herald Media

In my 40 plus years on Wall Street, I have met regiments of investment bankers. There have been none – i.e., not one – with the combined talent and integrity of Kevin Dunn.
