I have had the privilege of working with John Mahoney for over 20 years.  John has helped me in some very complex transactions & with a number of entrepreneurial ventures as well as my personal legal needs. John has always been an incredibly thoughtful, practical and sincere advocate for me and my family, and he has been a fantastic sounding board for major business decisions.  I have had experiences with a number of attorneys over my career, and I can confidently say that John has been the best attorney I have ever worked with — not only is he is incredibly smart, but more importantly, he clearly genuinely cares about his clients and takes their needs seriously.  I couldn’t recommend him more highly!

I’ve worked with John Mahoney for over thirty years and was one of his first clients.  I owned and operated a busy electrical contracting business, and John assisted with every legal matter, whether it be large contracts with new customers, contracting disputes and collection, and corporate, tax and employment matters. John helped me through the sale of the business and with our personal planning matters. I know that when I call John he will help me through any situation or direct me to someone who can help, whether it be another attorney in a specialized field or another advisor.  I’ve trusted John with all our matters and he is always available and willing to help.
