Larry Zeifman has over three decades of experience auditing and advising public and private companies. After leaving a ‘Big Four’ firm in 1985 to join Zeifmans, Larry served as the firm’s Managing Partner from 1988 until 2009 and continues to serve on its management committee.

Specializing in auditing, mergers & acquisitions, and consulting, Larry is responsible for servicing many of Zeifmans’ larger corporate clients, especially clients in the financial services and health care sectors. Larry’s clients rely on his advice on a range of domestic financial matters, as well as issues relating to the global corporate environment. He leads the Zeifmans’ Cannabis Team and served as a former director for the Ottawa Senators.

Larry’s understanding of global business facilitates his chairmanship of Nexia Canada (the Canadian division of Zeifmans’ international accounting network), and his membership of Nexia International’s marketing and business development committee.

Larry Zeifman is an active community volunteer. He is a past president of his synagogue, Beth Avraham Yoseph of Toronto (Canada’s largest Orthodox synagogue), is the Chairman of the Orthodox Union in Canada, and is a former Vice President of B’nai Brith Canada.

His passion for, and interest in, the State of Israel, and his years of extensive global travel have helped Zeifmans’ clients do business successfully in Israel and other world markets.
