Sean Brennan has extensive experience representing pharmaceutical companies in products liability litigation. Recognizing that pharmaceutical clients need counsel to plan, early on, how the multitude of cases not taken to trial will be effectively resolved, Sean has focused in recent years on designing and implementing global resolution programs. He has been retained to develop complex global settlements in multi-billion dollar mass tort litigation and to implement these programs from design through completion. The programs Sean has designed and his key role in the resolution of high profile products liability cases have earned him praise from all parties.
