Client Testimonial

Allergan Westport have worked very successfully with MJ Conroy for over 30 years on a wide range of Pharmaceutical construction projects. The commitment to the safe, timely delivery of quality projects within tight budgetary constraints by the MJ Conroy team is second to none and I would have no hesitation in recommending them for a range of Pharmaceutical / Medical Device type construction projects.
