For over a century, CP & Co. has served as a central administrative office providing professional financial services for the descendants of Charles Pratt and selected other private clients.

Founded in 1891 to manage the estate of Charles Pratt, a partner in Standard Oil, CP & Co. has since developed a wide range of custodial, investment, tax and accounting services.

In 1997, CP & Co. established Dosoris Trust Company as a wholly owned subsidiary to further provide trust and estate planning services for its clients.
