Joseph Pirrello


Joseph began his professional accounting career with a large international public accounting firm where he gained the knowledge and experience required in the assurance and management advisory service profession. This experience led him to an advisory services role for the small and medium sized owner manager sector.

In 1985, he became a sole practitioner helping fellow small business owners grow their business, while growing his own public practice.

In 1991, Joe became one of the founders of Williams & Partners, where he continues to act as a trusted advisor and business coach as well as an integral part of his clients’ peripheral professional advisory team in the manufacturing, processing, construction and real estate sectors.

Joseph served in protecting the public interest and upholding the reputation of the CA profession as a member of the Institute of Chartered Accountants of Ontario’s Practice Inspection Committee from 2006 to 2009.
