gunnercooke expands into California with privacy hire

August 3, 2026

International law firm gunnercooke has appointed Timothy Toohey as Partner, formally establishing the firm’s presence in California. This expansion extends gunnercooke’s US footprint from coast to coast, building on its New York headquarters, complemented by a well-established Chicago office. 

Toohey’s appointment marks a continuation of sustained growth for gunnercooke in the US. The firm has grown to 30 partners across the country, with plans to selectively add a number of partners before the end of the year. Toohey’s arrival will act as a launchpad for the firm on the West Coast.  

Toohey practised at Greenberg Glusker in Los Angeles, specialising in privacy, data security, cybersecurity and intellectual property for technology, media, entertainment clients. His experience includes acting in disputes involving a major motion picture franchise, including UK proceedings. He is certified as a privacy lawyer under both US and EU law, and studied at Berkeley Law, Harvard, Oxford University and Stanford.  

Tim Toohey, Partner, gunnercooke said“I am proud to be at the forefront of gunnercooke’s expansion into the California market, which is at the vanguard of technological change, particularly in the fields of privacy, intellectual property, cybersecurity and artificial intelligence. I am excited to be able to join an international firm who has pioneered a new model to deliver legal services in a world confronting multiple challenges from new and rapidly changing technology.” 

James Goulbourne, Chief of Staff, US, gunnercooke, commented, “Tim’s appointment makes clear the calibre of partner gunnercooke is focused on bringing into our US business: established, entrepreneurial, and committed to innovating. Our approach in the US has always been about quality over speed, bringing in experienced partners who want to be part of building a truly great firm. Tim is a clear example of that. An ambitious firm attracts ambitious lawyers, and that’s exactly why we’re thrilled to have Tim join us. It’s a strong signal of the momentum we’re building across the US, and there’s more to come.” 

The firm’s growth is underpinned by gunnercooke’s unique model: a modern international law firm that strips out bureaucracy and the outdated overheads burdening traditional firms, with client matters handled personally and directly by quality Partners, with local or global bespoke teams available as needed.
