About Harrison Pensa LLP

Harrison Pensa LLP is a full-service law firm headquartered in downtown London, Ontario, with a second office in St. Thomas. The firm formed in 1999 through the merger of two established London firms, Harrison Elwood and Pensa & Associates, bringing decades of business law and litigation experience together under one name. Today it advises individuals, families, and businesses across southwestern Ontario on corporate and commercial law, real estate, employment, family law, wills and estates, personal injury, and other areas, including agricultural law for the region's farming community.

The firm later opened its St. Thomas office, led by a civil litigation partner who joined to head the location and give clients in Elgin County a local base. Lawyers at Harrison Pensa have been recognized in the Best Lawyers in Canada rankings and by the Middlesex Family Law Association, and the firm is a long-time sponsor of the London Knights, serving as the team's official lawyers. It also established the Harrison Pensa Law Clerk Excellence Award at Fanshawe College to recognize students in the school's law clerk program.
