The story

Originally a banking law boutique firm, Manatt, Phelps & Phillips LLP was founded by Charles Taylor Manatt, a lawyer, politician and businessman, and Thomas Phelps, a banking and finance attorney, in Los Angeles, California as the "Manatt Law Firm". Litigation and sports lawyer Alan Rothenberg joined them soon after; Rothenberg remained a named partner in the firm until he moved to Latham & Watkins in 1990. Former U.S. Senator John V. Tunney was a named partner from 1976 until early 1987. L. Lee Phillips, an entertainment lawyer, joined the firm in 1977 and became a named partner in 1985. Democratic activist Mickey Kantor joined the firm in 1976; he was a named partner from 1991 until his departure in 1993 to become United States Trade Representative, and, later, Secretary of Commerce during the Clinton Administration.

The firm's headquarters moved to Century City, Los Angeles, on March 1, 2020.

Holocaust Survivors Justice Network

In 2007, Manatt and Bet Tzedek launched a nationwide pro bono program, the Holocaust Survivors Justice Network, to help holocaust survivors. The Network has since assisted thousands of survivors and has grown to be the single largest coordinated pro bono effort in U.S. history. At the height of its activity in 2009, clinics operated in 31 cities across the country with the assistance of more than 100 corporate partners, providing free legal services to survivors seeking German "Ghetto Work" reparations. The Network has been recognized by the American Bar Association, the National Law Journal and the Pro Bono Institute.

Divisions

Manatt organizes some of its specialty practices into standalone or separate divisions, similar to an 'industry group' as opposed to the traditional law firm 'practice group' structure. The division-system's purpose is to provide counsel and advice beyond legal issues by employing non-legal experts in topics relevant to the divisions focus.

Manatt Health

Manatt Health is a division of Manatt. Manatt Health professionals provide counsel on healthcare coverage and access, healthcare information technology, healthcare financing and reimbursement, and healthcare restructuring.

Manatt Health is composed of healthcare consultants, lawyers, project managers, technology strategists, analysts and policy advisors. They frequently publish by-lined articles and speak with media on major health industry issues.
