About Sherwin Law

Sherwin Law continues the law practice that Claire Sherwin began in St. Marys in 1996, and the firm has served St. Marys, Perth County, and the surrounding southwestern Ontario region for over 25 years. It's a small, general practice housed at 72 Wellington St. S. in the heart of town, offering real estate, estate planning, family law, business and corporate law, litigation, and mediation and arbitration services under one roof.

Claire Sherwin studied at the University of Alberta, earning both an undergraduate degree and a law degree there, then completed a Master of Laws in Alternative Dispute Resolution at Osgoode Hall Law School at York University. Admitted to the Ontario bar in 1996, Sherwin has practiced in St. Marys ever since, working as a trained mediator and a qualified Collaborative Family Law lawyer alongside the firm's general caseload. The real estate work spans residential, commercial, and agricultural transactions, including farm quota transfers, reflecting the rural character of the county the firm serves.
