Michael Ringler, who spent the past 22 years advising clients on deals at Wilson Sonsini Goodrich & Rosati, has left the Silicon Valley firm to join Skadden, Arps, Slate, Meagher & Flom.

Ringler joined the Skadden's Palo Alto office Monday as a partner in the firm's corporate, M&A practice.

“I have worked across the table from Skadden lawyers on numerous occasions, and I have seen firsthand the skill, creativity and client service they bring to bear,” Ringler said in a statement. “I am thrilled to practice alongside such highly regarded colleagues across the firm's platform.”

For the past two decades at Wilson Sonsini, he has advised strategic transactions, including mergers, acquisitions, divestitures, joint ventures and other transformative business combinations, and represented clients in corporate control issues, including unsolicited acquisition proposals, hostile takeovers, proxy contests and shareholder activism.

In 2015, Ringler was named as a Dealmaker of the Year by The American Lawyer for counseling online real estate service Trulia in its $3.5 billion merger with rival Zillow. Other notable clients in recent years include advising CA Technologies in its $19 billion sale to Broadcom; AppDynamics in its $3.8 billion sale to Cisco; and Flatiron Health in its $2 billion sale to Roche.

“Mike has a well-established reputation as a trusted adviser to boards and C-level executives,” said Leif King, head of the corporate, M&A practice in Skadden's Palo Alto office. “With more than 20 years representing companies on their most high-profile transactions and complex governance issues, Mike's experience will be of tremendous value to our clients.”

Skadden, which closed its San Francisco office in 2010, now has 73 lawyers working out of its sole Bay Area base in Palo Alto, and 28 of them are dedicated to the corporate practice.

A spokesman for Wilson Sonsini said that the firm thanks “Mike for his contributions to the firm and our clients, and wish him well.”
