Meet John E. Mahoney

John E. Mahoney Esq. became an attorney in 1997, and is a member of the Massachusetts (1997) and New Hampshire (2001) Bar Associations, having represented clients in both states for many years.

He began his career working for a firm closing a vast number of real estate transactions every month, but wanted to do more than just executing closings. After one year, he joined his Uncle’s general practice firm for about five years, gaining more in-depth real estate experience, and broader legal experience by adding small business and estate planning to his repertoire. In 2003, John decided to open his own firm and hasn’t looked back, helping thousands of clients along the way.
