“As an entrepreneur in RI, I have been involved in multiple aspects of various businesses and industries. Competent legal representation is one of the most important services I purchase. As a client of Duffy & Sweeney’s since 1997, I can state with conviction that Michael Sweeney and Bob Duffy along with their legal team and staff have been a critical aspect of the success of my various ventures. D&S has represented my companies in acquisitions, divestitures, equity and debt raises, customer contracts and other vital business law aspects. They have leveraged their many relationships in assisting me in establishing successful organizations. Their understanding of business law, finance and tax matters have made them more than just a legal firm from whom I am a client; they have become a trusted advisor whose opinions and counsel I highly value.”

“I utilized Duffy & Sweeney when purchasing my company from a foreign owned company (Japan). They were instrumental in navigating through the domestic and international laws resulting in a smooth transaction. Mike Sweeney headed the team. I found him and his staff to be professional; they took the time in explaining all of my options to ensure I was comfortable with signing the appropriate documents. I recently used Duffy & Sweeney to handle the legal work for the sale of my company to a large domestic company. Mike Sweeney oversaw the process while John (Ted) Scholhamer handled the details of the deal. Ted was extremely positive and professional during the entire negotiation process always felt Mike and Ted had my best interest in mind at all times. I would highly recommend Duffy & Sweeney for any corporate legal work.”
