GL Kreiner, Inc. (DBA DW Security) was founded out of GL Kreiner Insurance, Inc.  Gina Kreiner along with her husband Ed began the task of building the company from the ground up.  With over 30 years in the alarm industry and working in high level positions within other organizations, Ed used his experience to create the culture within the company.  The help needed to do this came from his (team) of children that have spent their entire lives around our industry.  Kelly, Samantha, Joe and Will all have played a key role in the development of the company.


The next phase of the company was achieved with the addition of Brian Burkholder with over 20 years of experience in the alarm and suppression industry and Don Wilson with over 30 years of experience growing business in the alarm industry.  Throughout the transformation of the company, the goal was to take all the positives from our previous experiences within the industry and apply them to grow GL Kreiner to over 40 employees and 25 trucks on the road.  With this backbone in place, GL Kreiner continues to serve our partners needs that include testing and inspections, service, installation and sales.


We are committed to providing our employees with a great environment to work, and our customers with world-class security & life safety solutions.


Our goal is to keep expanding our presence in the Pennsylvania area, where are roots come from.  We have also expanded into Maryland and surroundings areas.  We continue to go where ever our clients call us to meet their needs, regardless of geographic range.

Gina has a strong business background from running a successful Insurance company. She brings that customer service mentality to the alarm industry to make sure that every customer has the best possible experience with GLK.
