Rockefeller Capital Management today announced that it has strengthened its presence in Los Angeles with the addition of Maentz Machlovitch Group, an ex-Morgan Stanley trio with $1.5 billion in assets under management.

The team is led by Hans Maentz, a managing director and private wealth advisor, and Bern A. Machlovitch, a managing director and private wealth advisor. The group also includes Ben Helvey, team portfolio manager. They will operate as the Maentz Machlovitch Group at Rockefeller Capital Management.

The team has provided institutional investment services to Native American tribes and the Alaskan Native Corporations for nearly two decades. It also services wealthy individuals and families.

Both Maentz and Machlovitch began their Wall Street careers at Lehman Brothers in private client services in 2002. They moved to Morgan Stanley in 2008. Helvey joined Morgan Stanley in 2013 after serving as director in the private banking division of Credit Suisse in the U.S. for five years. Before that, he was with Lehman Brothers from 2004 to 2008.

Nathan Crair, managing director of the Southwest division of Rockefeller, said the firm is excited to have Maentz Machlovitch Group on board as it builds on the continued growth of its private wealth business. “The group’s deep experience in serving wealthy individuals and families, and their expertise in providing solutions to the unique financial services needs of Native American tribes, will help provide a differentiated wealth management experience to current and prospective clients throughout this region,” he said in a statement.

New York City-based Rockefeller in the past few weeks has expanded into new markets including Newport Beach, Calif.; San Antonio; and Denver. The addition of the Maentz Machlovitch Group brings its private wealth business to 48 teams across the nation.
