Meet The Team

Our Medical Science Liaisons (MSLs) and Managed Market Liaisons (MMLs) are field medical team members with comprehensive clinical, scientific, and/or research backgrounds. They facilitate the translation and dissemination of fundamental scientific, clinical, health economics, and outcomes research to key stakeholders within the health care and academic systems. Through educational programs and engaged discussion, they provide resources for shared decision-making to improve patient outcomes and quality metrics.
