Cory Chalmers President

Cory Chalmers founded Crime Scene Steri-Clean, LLC in 1995 while working as a paramedic and seeing a huge need to help people in crisis. In 1997, Cory was hired as a firefighter in Orange County California where he promoted quickly from firefighter to paramedic, and then to Captain. In 2011, Mr. Chalmers retired from the fire department in order to pursue the growth of his company to help those in the face of tragedy. His knowledge of city budgets, contracts, PO's, S.O.P.'s and budget restraints is key in contracting his services with over 4 dozen cities that Crime Scene Steri-Clean, LLC is contracted by. He has 14 years experience as a paramedic, 14 years with hazardous materials and emergency management, as well as biohazard response and remediation since 1995. Cory is often asked to be the keynote speaker at conferences and seminars throughout the United States and has been featured on a dozen or more television shows including his regular appearance with "Hoarders" on A&E. He is responsible for the rapid growth of Crime Scene Steri-Clean, LLC from an owner operator, home-based business to a multi-million dollar company with locations throughout the United States. Cory runs a worldwide Yahoo Talkgroup on crime scene cleanup as well as several websites to assist the public with valuable resources and information in their time of need. He is well known throughout the world as an industry leader.
