"We met with Thom more than a year ago to discuss installing a transponder capable of ADS-B in and out.  All of the instruments and radios in our airplane were either original from the 70s or over 20 years old.  We were ignorant about the newer electronics available and Thom spent quite a bit of time educating us on various combinations of Garmin instruments that may serve our wants and needs.  We wanted to upgrade some but not all of our panel, but also didn't want to waste money on certain equipment now that will be wasted in the future if we upgrade the panel further.  Thom helped us strike that balance.  We are VERY happy with Thom's shop's work, their integrity, their communications witb us before, during, and after the work.  It's been a great experience and we would highly recommend them."

"For my money and for my situation (e.g. a legacy autopilot in a retrofitted glass cockpit) there is no one better. He's not cheap but quality rarely is. He will take the time necessary to follow your issue to its conclusion. Recommended without hesitation."
– Peter Sloan, Google ★★★★★

"I can’t say enough good things about Thom and his entire team. Excellent communicators, excellent service, excellent work, and an excellent story involving a sensationally folded one dollar bill. This shop will be the first call for my avionics work from here forward."
–Richard Moscardelli, Google ★★★★★
Thom was very helpful, honest, and thorough. There were no hidden costs and everything was completed very quickly. I can't thank Thom enough for working me in to his busy schedule for a very intricate battery replacement. Even after my visit Thom called to check up and make sure everything was working well. Top quality service. Thanks again Thom.
