Warren is a corporate lawyer whose practice is transaction-driven and includes structuring start-ups, closing business acquisitions, completing secured loans, implementing tax-related reorganizations and everything in between. Warren likes closing deals, especially international deals.  But, he loves deals involving corporate social responsibility and triple-bottom line businesses.  He firmly believes that those kinds of business dealings can change capitalism and change the world.

Warren currently chairs the International Law Section of the Ontario Bar Association.  Additionally, in the O’Brien’s Encyclopedia of Forms, he co-authors Chapter 32 (International Transactions) and authors Chapter 33 (Joint Ventures).  Warren has an Honours Bachelor of Commerce (Hons. B. Comm.) from McMaster University and a Bachelor of Laws (LL. B) from the University of Toronto.   When he isn’t practicing law, he is at home with his wife and their cat Yoda.
