About Me

Aviation has been a part of my life since I was young, beginning with flight simulators and growing into becoming an FAA CFI/CFII/MEI with over 600 hours dual given so far. What started as a hobby has turned into a career and I'm more than happy to share that passion with others.

With a strong foundation in real-world flight instruction and a growing focus on the simulator side of aviation, I aim to bring that experience over to virtual instruction. My goal is to create an immersive, educational, and enjoyable experience for anyone looking to take their first few flights, work towards a new rating, or knock the rust off IFR procedures, I'm excited to help!

I've used simulators throughout my entire aviation journey and I'm a firm believer that at home simulators can make flight training more accessible, affordable, and effective.

Most of my experience is with G1000 avionics but I do have plenty of time flying conventional "steam gauges".
