Our Culture
We created Bison with a vision that families benefit from 3 simple concepts. Plan, Protect, and Prosper. Bison was founded by The Terry and Kim Pegula Family Office known as East Asset Management in conjunction with operating partner Teton Capital Partners founded by Brad Ball and his team of executives.
As Terry Pegula rose from petroleum engineer to Billionaire Oil and Gas Entrepreneur, Philanthropist, and Professional Sports Team Owner the family was amazed to see all the products, services, and capabilities that became available to them. Bison seeks to make these family office tools available to Bison clients.
