Microsemi Loses Mazzo From Board

Aliso Viejo-based Microsemi said late Wednesday that James V. Mazzo--the former CEO of Advanced Medical Optics--has resigned from the company's board. Microsemi did not say why Mazzo decided to leave the board, but said the resignation "did not arise as a result of any disagreement on any matter relating to Microsemi's operations, policies or practices." Mazzo is an operating partner at venture capital investment firm Versant Ventures, and also sits on the boards of AcuFocus, Neurotech Pharmaceuticals, and a number of other firms.
