G Davis Green, Former Pennsylvania State Treasurer

The investment advisory firm of O’Brien Greene & Co. was established in 1969 by Mr. G. Davis Greene, Jr.  Originally named Greene Associates, the firm’s offices were located in center city Philadelphia.  Mr. Greene, who was an alumnus of the College and Wharton School of the University of Pennsylvania, previously worked at the Federal Reserve Bank of Philadelphia and began his investment career with the firm of Lionel D. Edie & Co., before becoming a partner with Dearden & Greene.

Mr. Greene built Greene Associates into a diverse money management practice serving individuals, regional banks, pension funds, and not-for-profit organizations.  In 1987, in the aftermath of a scandal in the Pennsylvania Treasury Department, Mr. Greene was asked by Governor Robert P. Casey to take over the Department as Secretary.  In order to accept the appointment, Mr. Greene was required to divest himself from Greene Associates.  Ownership of the firm was taken over by Mr. Mark B. O’Brien, who came from the private bank Brown Brothers Harriman, and renamed the firm O’Brien Greene & Co.  Mr. O’Brien remains the firm’s president and CEO to this day.  Under his leadership the firm has maintained its diverse practice, providing investment management services to individuals, families, trusts, insurance companies, endowments, religious orders, and corporately sponsored 401(k) retirement plans.
