A huge thank you to Christopher Greb, 20 year Operations Manager of Macungie Ambulance Corp for visiting The Emmaus Rotary Club last week.  Chris delivered a fantastic overview and history on the The Macungie Ambulance Corp and how this organization has advanced since the late 50's.  Chris also gave a crash course on current day CPR and dispelled the previous historic mentality of how someone can help someone in cardiac distress.  Hope to see you again Chris.
