Lawrence F. O'Brien III

Founder, OB-C Group

Lawrence F. O’Brien, III, has been described by the Washington Post as a “major Democratic operative.” He was selected by The Hill newspaper as one of Washington’s “Top Lobbyists” in its first survey in 2007 and has been chosen every year subsequently.

Mr. O’Brien has been a long-standing participant in the House Democratic Congressional Campaign Committee’s (DCCC) maximum level individual donor program, the Speaker’s Cabinet, and in the “Pelosi Team 100” program.  Over a period of two decades, Mr. O’Brien has had an extensive degree of involvement and interaction with the House Democratic leadership, with myriad Democratic members across a wide array of House committees and with the leadership of the DCCC.

For more than twenty years, Mr. O’Brien has also been engaged at the most elevated participation level with the Democratic Senate Campaign Committee (DSCC). He has served as the Chair of the DSCC’s premier individual donor group, the Legacy Circle, since the inception of the program in 2006. He was designated a “Lifetime Member” of the Legacy Circle in 2014. In addition, he is the recipient of what the DSCC describes as one of the highest honors it can bestow, an award of lifetime membership in its “Majority Trust” program. In the award letter to Mr. O’Brien, Senator Schumer, then Chair of the DSCC, stated, “. . . I can’t think of a more qualified Democrat to receive this honor.”

Mr. O’Brien served as a member of the Carter Administration Treasury Department from 1977-1979. He worked with the Congress and various Executive Branch departments on legislative matters involving income, estate, excise and energy taxes, trade and domestic finance issues.

He was an associate attorney in tax from 1972-1977 and then a full tax partner in the law firm of Breed, Abbott & Morgan for the period 1979-1983. He was a full tax partner in the law firm of Dewey Ballantine, in its Washington, D.C. office, from 1983 until 1993. He withdrew in 1993 to co-found the firm of O’Brien-Calio. In 2001, that lobbying partnership was succeeded by OB-C Group.

Mr. O’Brien is a founding incorporator, a past president and an original and still serving board member of the National Archives Foundation, a tax-exempt charitable and educational organization affiliated with the National Archives in Washington, D.C. The “Lawrence F. O’Brien Gallery,” the Archives’ display space its for major temporary exhibits, was dedicated and opened in the National Archives building in 2004 and is named in memory of Mr. O’Brien’s deceased father.

Mr. O’Brien received a B.A. degree with honors from Harvard College in 1967 and a J.D. degree from Columbia University School of Law in 1972. He served a 13-month tour of duty in Viet-Nam with the U.S. Army in 1969-1970 and was awarded the Bronze Star. He is a native of Springfield, Massachusetts.
