About Feeley O'Brien Law

Feeley O'Brien Law is a family and immigration law firm in downtown Oshawa, Ontario, operating through Annesa Feeley O'Brien Professional Corporation. The firm opened its doors in February 2020. Its founder, Annesa Feeley O'Brien, earned an honours law degree from the National University of Ireland, Galway in 2005, qualified as a solicitor in Ireland in 2009, and was called to the bar in Ontario in 2011 after articling with family law counsel in Whitby.

Feeley O'Brien Law handles the full range of family law work, including parenting and support disputes, separation agreements, and divorce, and it also practices immigration law with a focus on family reunification and sponsorship applications. At the appeal level of the Federal Court, the firm succeeded in overturning a denial of a spousal visa by Citizenship and Immigration Canada. The firm's name and branding draw on the Claddagh ring, a piece of jewellery from Annesa Feeley O'Brien's home village in County Galway, Ireland, whose design of two clasped hands, a heart, and a crown is said to represent friendship, love, and loyalty. Feeley O'Brien Law serves clients across Durham Region and into the Kawartha Lakes area, including Cobourg, Peterborough, and Lindsay.
