About Petrone & Partners

Petrone & Partners is an independent, full-service law firm based in Thunder Bay, Ontario, with 13 partners and associates covering nearly every primary area of law: real estate, wills and estate planning, corporate and commercial law, family law, personal injury, civil litigation, employment law, administrative law, Aboriginal law, and criminal defence. The firm calls itself Thunder Bay's only full-service law firm, and its lawyers can serve clients in English, Italian, and French.

The practice traces back to 1953, when Alfred Petrone opened a one-man office in Port Arthur, Ontario. As partners joined over the decades the firm grew into Petrone Hornak Garofalo Mauro, then simplified its name to Petrone & Partners in 2016, in honour of its founder. The team today includes lawyers called to the bar as far back as the 1980s alongside more recent calls, giving the firm a mix of long-standing and newer counsel under one roof.
