Meet the instruction team.


Bob Stedman | CSIP Instructor & President

He joined IA in 2010 and his leadership has helped form the company into what it is today.

Chuck Gensler | CSIP Chief Instructor Emeritus

Chuck is a lifelong aviation educator, which is his dream come true. He spent most of his 25-year career in the U. S. Air Force training youngsters to be the best of the best. Now, in “retirement,” he’s teaching the rest of us to be the best we can be. Never one to rest on his considerable laurels, Chuck was also one of the first Cirrus Standardized Instructor Pilots in Colorado, and has earned the FAA’s national 2017 Flight Instructor of the Year!

Colin Prenger | Instructor & Media

Colin fell in love with aviation at the age of 13 when his parents gifted him a discovery flight in Scottsdale, Arizona. In the summer of 2011, Colin traveled to Independence Aviation to start his aviation career. He got his Private Pilot Certificate in just 4 weeks! After several years as an IA customer, Colin became one of IA’s instructors, and is an accomplished photographer and videographer.

He has since earned a B.S. from Purdue University in Professional Flight with a minor in Business Management. He came to I.A. to be a part of a world class flight school and to be near the mountains to fuel his other passions, hiking and snowboarding.

He was inducted into the South Dakota Aviation Hall of Fame, is on the Board of Trustees for the National Aviation Hall of Fame in Dayton, OH, and currently flies one of a handful of B-17’s still in operation!

Masten Hamlin | Instructor

Masten has been an instructor since the early 1990s. He brings to the classroom significant turbine and charter experience garnered from his time with one of the leading jet charter operations in the Rocky Mountain region. His teaching skills and in-depth knowledge of all aspects of aviation are widely respected throughout the Centennial Airport community, as well as by the fortunate IA students he mentors.

Jack Brennan | Instructor

Jack has spent so much time in the cockpit in his 40+ year career, that he’s actually a little uncomfortable on the ground, except when he’s fishing. He has clocked thousands and thousands of hours as a Navy pilot, instructor, and as a Continental Airlines captain for 29 years. We think he’s one of the best catches we’ve ever made – and so do his students!

Kevin Shepard | Instructor

Kevin is one of our career-change educators. He started flying in 1988 and in 2001 began teaching. When he is not working at his full-time job for a large aviation company he brings his joy of teaching and flying to the IA team. Kevin comes with a bonus: He can also help you fly radio control models which is his other aviation passion!

Brendon Eddy | Instructor

Brendon first started flying after graduating college with a degree in criminal justice and decided to change career paths. After a discovery flight in a Cirrus SR22 at a small airport outside his home town of Philadelphia, he knew right away it was a goal and lifestyle he wanted to pursue. Training and receiving all his ratings in Cirrus aircraft and multi engines on the east coast, a change of scenery and the challenge of mountain flying brought him to Denver to join the IA team.

Ben Barash | Instructor

Ben’s lifelong passion for aviation led him to earn his Private Pilot certificate right out of high school. He went on to get his masters degree in Mechanical Engineering and spent his early career designing and testing turbine aircraft engines. Ben is now a corporate pilot flying a Challenger 350, but his love of general aviation has also been keeping him busy with the Civil Air Patrol, flying for a skydiving company, Pilots N Paws missions, as well as teaching others how to fly here at IA!
