JPM began operations in August of 1959 when Joseph Melvin first opened his doors in Ardmore, PA. Our dedication to our clients’ success helped that small suburban office grow into a highly respected regional accounting firm where three generations of Melvins have served clients across several states. Out of our offices in Philadelphia and New York we have practiced, collaborated and consulted for more than 50 years. Our clients have depended on us, and we on them, for all of that time. Our firm consists of experienced accounting professionals, who strive every day to adapt and change in step with the needs of our clients.
