Executive Management Team

John Milligan, CEO and Managing Principal

John Milligan is the Managing Principal of Milligan & Company, LLC, the largest minority-owned consulting and CPA firm headquartered in Pennsylvania.  He is a Certified Public Accountant licensed in Pennsylvania, New Jersey, Delaware, Washington DC, and Maryland.  John graduated from Temple University in 1975 (Magna Cum Laude) with a degree in Accounting.

After graduation, John joined the international accounting firm of PricewaterhouseCoopers (formerly Coopers & Lybrand), where he worked for nine years in their Philadelphia Office.  He was a manager in their Emerging Business Department for three years. This department specialized in servicing small and medium sized businesses.  His passion for small business development, combined with his expertise in assisting new enterprises, became the cornerstone of the firm, John Milligan, CPA, founded in 1985, which later evolved into Milligan & Company, LLC.

During its over 30-year history, Milligan has grown from a CPA firm into a nationwide, leading minority-owned small business.
