John Tregenza
Chair, Investment Advisory Committee
Development Committee
Cornerstone Campaign
Board member since 2006
John Tregenza’s entire career has been spent in various areas of financial services: investment and private banking, and wealth management. He began with the National Shawmut Bank of Boston, and then migrated to New York City in 1975 to enter into an extended “liaison” with French financial institutions: first, Credit Lyonnais, in New York and Miami; then Suez Groupe and Banque Indosuez in New York.
His tenure at Indosuez also included 10 years in Europe (Paris, Brussels, and London), as a member of the international management group. He returned to the United States in 1997, coming to San Francisco for successive stints at First Republic Bank and The Mechanics Bank, forging relationships in private banking and investment management.
Tregenza moved away from banking in 2006, and joined the independent, privately-owned investment and wealth management firm Whittier Trust Company, in San Francisco, where he directs advisory services activities.

Special Interests: Sailing, fly-fishing, travel, and amateur radio
