I have been a customer since Fullerton Air Parts (Flo Irwin). That should speak volumes of the service I have received from Military Fasteners. In the early days, I had a variety of planes and was based out of Orange County Airport. At the time, the airport was surrounded by bean fields. I, and some of my friends, would frequently fly into Fullerton airport for lunch, the pick up whatever supplies we needed from Flo. She was a great lady, and I am glad that she passed on such a wonderful legacy. I am certain that she would be very proud of what she started, and proud of you all for building on her meager beginnings.

Have placed many orders in the past months with sales representative Brittany Cornish and couldn't be more pleased ! She is always a joy to speak with, and she always makes sure that my orders are delivered on time. She's a great asset to your team but I'm sure you already know that.
