Mark Hiller and Ray went above and beyond to get our hylon extinguisher certified. We had engine issues so they waited here for mechanics to try and resolve. Finally we had to call it a day sent them to go home. Just to call them back to complete the inspection. They willingly turned around and came back the same evening knowing they still had an hour drive home after. Because of their kindness we can continue our travels to Florida in the morning. Thank You!! Would highly recommend.
