Duffy & Sweeney provided excellent counsel and administration for the sale of our business to a large international manufacturing company. They were instrumental to the transaction's success, flexible and effective with the negotiations, complexities, and inevitable set-backs, and they provided strong, in-house expertise for specific matters, such as employee benefits and environmental due diligence. I strongly recommend Mike Sweeney and his team for legal M&A work for mid-market transactions.

Mergers & Acquisitions Law

Mike Sweeney at Duffy & Sweeney is a clear and strong leader. The best surprise was the expertise of the firm's attorneys; each was superb in their lane. Each person was responsive, patient and efficient. Each person put their head down when it was time to close the deal. Each understood how and when to hold ground. Each lawyer was confident and assured in a simple, understated manner. This way of being was by far, the firm's greatest strength and a fine reflection of the leadership there. In this line of work, there are a thousand things that can go wrong. Duffy & Sweeney pulled our deal through as we envisioned.

Commercial Litigation

Working with Stacey Nakasian at Duffy & Sweeney on my only arbitration ever was an amazing experience. We won a full award and our team was clearly superior to our competition. It felt good to have the best attorney in the room!

Matt Sluter New England Construction

Commercial Litigation

I was fortunate enough to have found Stacey Nakasian of Duffy & Sweeney last year and she took over my case. Prior to working with Stacey, I was certainly losing an uphill battle and was also completely deflated with the legal system and processes. She managed to fight tooth and nail through mediation to deliver an outcome that I was not only comfortable with but also relieved to reach. Both Stacey and her team at Duffy & Sweeney were understanding, efficient, communicative and provided me with confidence that the fate of my lawsuit was in the best of hands. I couldn't be more grateful of the work that Stacey did, the confidence that she conveyed and the effectiveness of her approach. I would highly recommend her to anyone.

Colin Kane The Peregrine Group LLC

Litigation - Trusts & Estates

I worked with Stacey Nakasian of Duffy & Sweeney for over two years settling my Aunt's Rhode Island estate. The legal matters included estate gifting, land transfers and time consuming litigation concerning incompetent and conflicted prior estate planning. Not only was Stacey highly legally trained, on point, timely and professional, but she also had the people skills and patience to deal with my elderly father in his capacity as trustee and executor. I have worked with many lawyers over the course of my legal career in Ohio and she exceeded all my expectations. I would highly recommend Stacey and Duffy Sweeney to anyone seeking Rhode Island legal services.
