Giving Back to Our Communities

Per Mar believes in giving back to the communities we serve by actively volunteering and giving monetary support to local organizations. For that reason, we established our own Charity Fund in 1980, which is an internal account funded completely by employees and the company. Since 2001, Per Mar has matched every employee contribution dollar-for-dollar, which enables all of us to do more for our communities! To date, contributions total $1.2 million and counting!

We utilize Per Mar because they care about what the customer needs and wants. Service is a big deal for our company and Per Mar does it well!"
