About Kathy O'Brien

Kathy’s practice is focused on corporate and commercial matters. She regularly speaks to boards of not-for-profit and charitable corporations to advise them of their governance and charitable law responsibilities, including providing advice on hospital, foundation and association by-laws. Kathy works with healthcare organizations and foundations to establish appropriate governance structures and policies to facilitate and maintain healthy, cooperative relationships.

Kathy has worked with Ontario health service providers for over 20 years, facilitating restructurings and realignments within the healthcare sector, and implementing integrations of all kinds.
