Zeno Group, sister firm to Edelman, will open a sixth office in Silicon Valley on December 1. The new office will serve as the firm’s HQ for its tech practice, which the firm says has grown over the past two years. Zeno Group already has office in New York, Chicago, Los Angeles, Dallas, and Toronto.

Todd Irwin, MD of technology, will run the new office. He’ll be joined by four VPs to lead the operation: Victoria Brown, Monica Walsh, Katie Wood Znameroski, and Mary Ellen Ynes. All of these execs were previously with Edelman in San Mateo, where Irwin was EVP and GM. The roster of Zeno clients includes VeriFone Systems, Life Technologies, Q-Cells, and The Churchill Club.

Maria Amundson will become EVP of Edelman’s San Mateo office, starting December 1.
