About Potestio Law

Potestio Law began in Thunder Bay in 1986, when Tony Potestio started a general litigation practice there. Potestio still leads the firm today as managing partner. Four decades on, the firm remains headquartered in Thunder Bay and has added offices in Vaughan and in downtown Toronto on University Avenue, extending its reach into southern Ontario.

The firm's caseload covers personal injury, family law, commercial litigation, corporate law, insurance disputes, employment law, human rights and municipal and planning law. Potestio, whose practice centres on personal injury and civil litigation, is fluent in English and Italian. The associate team includes Monica Zakhari, who holds an LL.B. from the University of Liverpool and works across employment, personal injury, estate and civil litigation files; Alia Khan, a University of Toronto Juris Doctor who focuses on family and estate disputes; Jessi Ruberto, whose background spans real estate, municipal property and economic development; and Rod Johansen, who advises on business transaction structure and financing.
