Jonathan Guss


Senior Advisor

Johnathan Guss

Jonathan brings senior strategic counsel and decades of executive and advisory experience to Santis Health.

From 2005 through 2011, Jonathan served as the CEO of the Ontario Medical Association, gaining significant exposure to all facets of the health care system. Upon his arrival, he worked with the board to initiate and implement a Strategic Plan that covered the fundamental issues facing the OMA as an organization that represents and serves as negotiator for all of Ontario’s physicians and as an association provides an array of essential services to the profession. Based on the plan, the Board initiated a major governance review, which restructured the Board’s committees and adjusted the flow of information for Board decision-making and the performance of its duties. The plan also spawned a major new communications and public affairs strategy [implemented by Patrick Nelson], which guided the Association’s approach in the following two rounds of negotiations.

Jonathan was also responsible for the turnaround of the OMA subsidiary, OntarioMD, which subsequently placed Electronic Medical Record (EMR) technology in the hands of over 11,000 Ontario physicians.

Prior to his tenure at the OMA, Jonathan ran the Credit Union Central of Ontario for over twelve years, where he envisioned and engineered the merger with BC Central Credit Union to create Central1, and prior to that served as a diplomat in the Canadian foreign service.

Jonathan has also served on numerous boards, including the University of Guelph, the Harvard Alumni Association, Credit Union Central of Canada, OntarioMD, the Institute for Quality Management in Healthcare, a trust company and two insurance companies. He is currently the Chair of the University of Guelph’s President’s Advisory Board of the Health for Life initiative.

Jonathan has a law degree from the University of Toronto and a degree in economics from Harvard University.
