Laboratory Operations Manager @ Acorn Group of Companies

About

I’m an experienced Lab Manager with a strong foundation in pharmaceutical sciences, health economics, and regulatory compliance. I lead with a people-first approach and believe that the slowest team member determines the pace — a principle that guides how I build and mentor teams. My focus is on operational efficiency, method validation, and regulatory readiness. I’m passionate about optimizing systems that improve testing turnaround times and ensure quality assurance at every stage. I’m always open to meaningful conversations about growth, innovation, and ways to contribute to mission-driven healthcare or pharmaceutical environments
