Operational Excellence

SAS provides the very best design, service, installation, and inspections. We value our relationships with our clients and work every day to exceed expectations.  We constantly train our technicians and staff on current and new products and procedures. 

Our primary business model is to not hold clients hostage through technology. 
Each client has unique challenges that are matched with the manufacturer and will effectively meet the requirements called out by the client.  It is a 100% work with approach when we are designing and installing.

The most important value to SAS is for our clients to get a live person, not an automated message, when they call our office during our normal operating hours and for our clients to know they are talking to someone who can help them.  And to take care of our clients’ needs.
