Madison Pirtle

Hi I’m Madi Pirtle, HSE Consultant with SevenGen.  I enjoy helping our clients with the full scope of environmental, safety, or industrial hygiene needs.  I interned with SevenGen during my time at the University of Saint Francis, where I earned bachelor's degrees in Environmental Science and Business Administration.  As an intern, I gained a broad foundation of experience in environmental permitting, state and federal reporting, and plan writing, as well as assisting our Safety and IH teams.  After graduating, I followed my husband to Alabama where I worked as an Environmental Engineer in an industrial paper mill where I expanded my knowledge of experience in environmental policy, compliance, and indicatives.  I recently had the privilege of moving back to Indiana and rejoining the SevenGen team!  I believe my time on the receiving end of EHS consulting in a heavy industry environment coupled with the experience and development SevenGen provides has helped me learn how to best meet our clients’ needs and deliver exceptional service.

Outside of work, I enjoy spending time outdoors with my husband and our growing family, which includes three dogs and a baby on the way.  A few of my favorite outdoor activities include running, walking my dogs, cooking for friends, and practicing yoga.
