Two months after losing its San Diego office managing partner, Buchanan Ingersoll said Thursday it has acquired seven-lawyer San Diego law firm Alhadeff & Solar. Buchanan said it will maintain its four-lawyer office in Del Mar, Calif., as well as its new one in downtown San Diego that opens officially Friday.

The latest additions are led by partners Sam Alhadeff and Keith Solar, who handle business law, litigation and water law matters, among others. Solar's practice revolves around water law and in the tuna industry, with clients such as Basin Water Inc., South Pacific Tuna Corp., Chicken of the Sea International and FCF Fishery Co. Alhadeff has a land-use and environmental law practice with clients such as Beazer Homes, Lennar Corp., D.R. Horton. Inc., Standard Pacific Homes, Pulte Homes Inc./Del Webb and Meritage Homes Corp.

The acquisition comes after the April 3 departures of San Diego office managing partner Daniel T. Pascucci, who also led the firm's California litigation practice, and intellectual property litigation partner Andrew Skale for Boston's Mintz Levin Cohn Ferris Glovsky & Popeo.

Buchanan Ingersoll is based in Pittsburgh and has 80 lawyers in Philadelphia. It has 550 lawyers firmwide.
