First Defense Values


Our ability to be accountable and to hold our team accountable comes down to the core of our identity—as evidenced in our character, courage, and commitment


We preach over communication! Up front, clear, and precise communication with our team, customers, and vending partners.  


We continually reinvest back into our team ensuring we give customers: knowledgeable, well trained, and confident staff that have the solutions to fix complicated problems. 


Transparency is key. Simply- we say what we are going to do and do what we said we would do. Productive partnerships are built on honesty and respect.


We will always do what’s right. We believe we are judged on how we respond to a situation rather than how the situation came about. 


Push past the status quo of our industry with new and progressive ideas and unique solutions.
