Holmes promotes Shane Costelloe to partner

Corporate-law firm Holmes has appointed Shane Costelloe (pictured) as a partner and head of its employment team.

Costelloe specialises in employment law, corporate, commercial, and public-sector work.

The corporate lawyer, who began his career with the firm in 2012, advises corporate and public-sector clients on a range of issues, from recruitment to retirement.

He has extensive experience drafting commercial agreements, and advising on corporate matters and transactions – including mergers and acquisitions.


Holmes, formerly Holmes O’Malley Sexton, has three Irish offices, and a London office.

Managing partner Harry Fehilly said that the latest appointment was a reflection of the continued growth within the firm’s corporate team.

Costelloe’s move is one of a series of internal appointments within the corporate team, alongside the promotions of Ciara Downes, Melissa Regan, and Mikhaela O’Shaughnessy.
