Free consultationAbout KosinSka O'Shea Law
Kosinska O'Shea Law is a two-lawyer firm in Burlington, Ontario, formed when Dorothy Kosinska and Grant O'Shea, who together bring more than 20 years of combined experience, brought their separate practices together. Kosinska spent over a decade practicing exclusively in family law, including time at a small Toronto family law firm and a litigation-focused Burlington practice with appearances before the Ontario Court of Justice and the Superior Court. O'Shea worked at a large Hamilton full-service firm before running an independent real estate and wills practice for more than five years, and the two joined forces to offer a wider range of services from one office.
The firm now practices family law, including collaborative family law, along with real estate and wills and estates, from an office in Burlington's Burloak Towers near the QEW. Kosinska holds a collaborative practice certification through the Ontario Association of Collaborative Professionals and co-authored two Thomson Reuters Carswell publications, Domestic Contracts and Parenting Law and Practice in Canada. The firm also serves clients in Polish as well as English.
