From Liverpool to New York 

O'Connor Davies, LLP has roots that stretch all the way back to 1891.  That was the year W. Sanders Davies (who was born in Liverpool, England, in 1862) crossed the Atlantic and began practicing accounting in New York.  Davies brought a history of dealing with U.S. subsidiaries of overseas companies to the firm (which is one of O'Connor Davies'  specialties).  Around the turn of the 19th century, Davies helped develop accounting as a profession in the U.S., and even had a hand in creating CPA licensing standards, which were modeled after England's chartered accountancy profession. 

In the mid 1940s, two accounting firms were formed that would later become part of the modern ODMD.  In 1945, the firm Bennett Kielson Storch DeSantis was established, which later gave ODMD a foothold in government and municipal services.  And in 1947, Ed O'Connor established a public accounting firm specializing in real estate and construction.  In the 1950s, Robert Davies, heir to W. Sanders Davies, began building the firm's not-for-profit and international practices.  In 1953, Edward Munns began a long career of providing services to charitable community-based organizations, and in the 1960s, Tom Dobbins joined the team.  Dobbins introduced computer processing for patient bills and accounting for religious orders and nursing home facilities. 

Today, O'Connor Davies is headquartered in New York City and specializes in numerous industry practice areas.  It is one of the largest accounting and consulting firms in the New York tristate area, with 70 partners and more than 400 professionals on staff.  Two of the firm's more notable clients have been Furness Withy Steamship Company and Major League Baseball's New York Yankees.  A member of the Davies family has been a senior partner of the firm for over 11 decades. 

The firm's five offices are located in Manhattan, Harrison and White Plains, N.Y.; Paramus, N.J.; and Stamford, Conn.  ODMD also serves clients internationally, and is a member of PFK International, a network of accounting and advisory firms located in 470 offices in 125 countries.
