LOS ANGELES-Allen Matkins Leck Gamble Mallory & Natsis has elected David Osias as the firm's new managing partner. Osias will succeed Brian Leck, who has served as managing partner since the law firm's founding in 1977.

Osias, who will step into his new role on July 1, will be based in San Diego but will spend a significant amount of his time in the firm's Los Angeles and San Francisco offices. He joined the San Diego office of Allen Matkins on July 1, 1991, and has been actively involved in firm management during his 20-year tenure. He is the chair of both the bankruptcy and creditors' rights and the water resources practice groups. He is also a long-time member of the management committee, a frequent member of the compensation committee, and a member of the firm's strategic planning committee.

Osias notes that Leck has positioned the law firm to grow its market share in litigation, labor and employment, environmental, finance and restructuring practices during the economic downturn. He also cited the firm's traditional strength in real estate.
