Resourced by many ‘smart, strategic and hardworking partners and associates’, including a number of highly skilled advocates, Houston-based litigation boutique Gibbs & Bruns LLP’s reputation has been predicated on its ability to try cases in courts throughout the country. David Sheeren represents core client PIMCO in a number of ongoing matters, including against US Bank and trustees for 113 Bear Stearns Legacy RMBS trusts. A ‘formidable opponent’, seasoned trial lawyer Kathy Patrick, who co-heads the team alongside Sheeran, was also central to the firm’s successes against Wall Street, although her industry focus extends beyond the financial services sector to also include energy-related securities litigation.
