Retirement planning is far more than a bulleted item in a list of fiduciary services. It’s a highly specialized area of financial expertise—one we’ve practiced with passion since 1945, right here in Western Massachusetts. Meet the specialists whose knowledge, experience, and client-focused commitment have made Pension & Benefits Associates the region’s premiere independent resource of its kind.
