Summary: A highly experienced partner has been added to the mergers and acquisition team in the Palo Alto office of Cooley.

The mergers and acquisition team at Cooley has welcomed a new partner to their group in the Palo Alto office. Steven Tonsfeldt will be joining the firm from O’Melveny & Myers. Tonsfeldt was the chair of the global M&A and private equity practice at O’Melveny & Myers.

Cooley M&A practice head Barbara Borden says, “Steve is a superb and seasoned M&A lawyer who is known and admired throughout our industry. Cooley is delivering record results across the corporate spectrum: in 2015 we handled a total of 187 M&A transactions with an aggregate deal value of $44 billion. Steve will be a tremendous addition to our M&A team, and a great asset to clients seeking sophisticated advice on their most critical transactions.”
