Welcome to the Mid Atlantic Service Managers Association website.  We are the only association in Maryland dedicated to the advancement of oil heating service managers and technicans.  This association was formerly known as Washington-Metro Oil Heat Service Managers Association.  We decided to change the name to better describe the location of our members.  As a member of the Mid Atlantic Service Managers Association, you are also a member of our National Oil & Energy Service Professionals.  We are a not for profit organization that is dedicated to the advancement of all types of heating, cooling and domestic water heating systems through education and training. We meet regularly throughout the year. Most of our meetings include a speaker to educate us on various topics ranging from info about the latest equipment to heating and cooling fundamentals to business issues.
