Vonda Benson NAFI MCFIVonda Benson, MCFI 1/2024-1/2026:

After a discovery flight at age 50, Benson researched aviation and discovered the industry was lacking professional full-time flight instructors. Her husband Brian was surprised when she announced she was going to retire from her 30-year career with the Wisconsin Department of Corrections to finish her journey to become a full-time flight instructor and that they were going to start their own business. Brian put his own flight lessons on hold and supported her journey.

After obtaining her instructor certificate in May 2020 and CFII in December of that year, Brian was the third student she signed off for a checkride. Brian is now a pilot, an Advanced Ground Instructor, and is working on his instrument rating.

Together, they own a thriving flight school in central Wisconsin where an emphasis is placed on ground instruction along with the flight instruction. They are adding an additional full-time flight instructor this year. They value building strong relationships with the aviation industry across the state. Benson says her favorite aspect of being an instructor is watching students build their internal skills, which she loves to watch happen in real time. She is honored to make a difference in two totally different fields — corrections and aviation. Benson’s own journey to becoming a CFI was filled with many challenges, the biggest of which was figuring out her learning style. As a result, her motto has become: If we don’t quit, we win.

Joe Bertapelle NAFI MCFIJoeseph Bertapelle, MCFI 02/2023-02/2025:

This is Bertapelle's second NAFI Master Instructor accreditation.

Bertapelle owns the Augusta Flight Center (AFC), a flight school at August Municipal Airport in Augusta, Kansas. He arrived in Wichita in late 2006 as a KC-135 navigator for the United States Air Force, going on multiple temporary duties and seven deployments. He became a USAF instructor and evaluator for the navigator schoolhouse, obtaining several squadron and group-level awards. Bertapelle received an honorary discharge from the Air Force in 2012 as a captain for mission-planning software and worked on base as an independent contractor for another seven years to support the KC-135 and the KC-46.

He created Joe Bravo Aviation, LLC to diversify his student base and offer flight instruction to the public. Teaching flight instruction at multiple airports in his spare time, his bolstered reputation afforded him the opportunity to teach at Beechcraft’s Cessna Flying Club, a rare exception to its employee-only stipulation. In 2019, Bertapelle was sought to teach at Flight Safety International in the Caravan G1000 program until 2020 when downsizing from the COVID-19 pandemic furloughed him. Through this seemingly unfortunate circumstance, he has been able to focus his efforts entirely on AFC, becoming its owner in August 2020. It now has a current fleet of 11 planes, ranging from the Cessna 172 through the Beech Sierra. He is checked out in more than 50 different models of GA aircraft and routinely travels to meet students, maintaining a competitive level of expertise, proficiency, and flexibility. He offers instruction of all levels on advanced avionics in aircraft, aerobatic maneuvers, commercial, IFR, tailwheel, and upset training.

Bertapelle has CFI, CFII, MEII, AGI, and remote pilot ratings, and is a Gold Seal Instructor and aircraft dispatcher. He is vice president of the International Aerobatic Club Chapter 119, which recently awarded four aerobatic scholarships to AFC to help students pursue their dreams of aerobatic instruction.

Alvin Chung NAFI MCFI

Alvin Chung, MCFI 12/2023-12/2025:

Chung’s fascination with aviation started as a child through his father’s work as a gate agent for a major airline. Chung’s fascination with flight grew as he traveled the world flying standby with his family. His father, a private pilot, would explain aerodynamics, winglets, and flaps to his son, pointing from the window seat.

At age 14, Chung joined the Civil Air Patrol and gained early flight experience, which helped him achieve his first solo flight at age 16 in 2016. Chung's experience with the Civil Air Patrol and Salt Lake City International Airport led to advocating for a United Service Organization (USO) lounge there, which was established in February 2022.

A few months prior, Chung had earned his flight instructor certificate. He teaches private students and students at the Utah Civil Air Patrol. Chung has a student pass rate of more than 90 percent and is a Gold Seal flight instructor. Chung’s teaching philosophy is about investing time to know his students inside and out the airplane. He believes sharing the love for aviation is what teaching is all about. “Teaching isn’t about getting me hours to my next job,” he said. “It’s about showing others that you care about their experience, and they do better because of it.”

Chung also works in hospitality and tourism development in the Moab, Utah area while continuing to build his aviation skills. He has assisted a Part 135 tourism company expand and is helping to set up partnerships with other tourism projects.

Aaron Dabney MCFIAaron Dabney, MCFI 8/2013-12/2025:

This is Dabney’s sixth NAFI Master accreditation and distinguishes him as a Bronze Master Legacy Instructor.

Dabney’s earliest memories are of aviation. He grew up riding in the family J-3 Cub with his grandfather and uncle, and his family claims he was three months old the first time he went up. His Saturdays were spent at historic Ball Airport in Victoria, Texas, where he consumed a steady diet of flying stories from World War II veterans, agricultural pilots, and the many other characters who populated that gathering spot. Dabney eventually soloed the family Cub and is now its caretaker.

In 2009, Dabney earned his CFI/II and co-founded his first flight school with a close friend and business partner. It was there that he fell in love with teaching and running a small independent business, and he’s never looked back. He credits small business ownership for making him a better flight instructor, and vice-versa.

He and his wife Alisa now own Waco Flight Training in Waco, Texas, where he trains and mentors the instructional staff with a focus on serving as teachers rather than right-seat pilots. He is also an active contributor to the aviation sciences program at Baylor University. He serves there as assistant chief ground instructor and teaches the introductory course, as well as a first-of-its-kind, standalone course on the fundamentals of instructing.

Dabney is an active volunteer with NAFI, assisting with the Master Flight Instructor program and coordinating the monthly MentorLIVE broadcast.  In 2022, he was elected to his first three-year term on the board of directors.

He holds a Bachelor of Arts and Master of Science degree in education from Baylor University. He has been married to his college sweetheart Alisa for nearly 20 years. They love to travel in their free time, including a yearly non-negotiable pilgrimage to EAA AirVenture Oshkosh.

Bryan Gutraj NAFI Associate MCFIBryan Gutraj, Associate MCFI 10/2022-10/2024:

Born in Waukegan, Illinois, Gutraj’s passion for aviation began as a child on a commercial cross-country flight on United Airlines to Disneyland. Later, he studied accounting at Eastern Illinois University and began his private pilot training shortly after graduation. While attending law school in Chicago, Gutraj would take the Orange Line “L” to Midway Airport for flight lessons in his “free time” and earned his private pilot certificate in 1998 at Midway. He went on to earn his instrument rating at Stick and Rudder Flying Club in Waukegan. He took a hiatus from aviation for a few years while he built his law and accounting firms in Illinois. 

Although Gutraj did not log many hours over the next decade, he stayed close to aviation by assisting pilots, aircraft owners, mechanics, flight schools, and others with their business, tax, and estate planning matters. Finally, thanks to the persistence of several of those clients, he decided to return to his passion for flying and began working on his commercial pilot certificate in a Cessna 182RG based in Marshfield, Wisconsin. He has since added a multi-engine rating and CFI, CFII, and MEI to his certificates.

Although Gutraj’s pilot and flight instructor training was conducted almost exclusively in old school steam gauge six pack Cessnas, at the urging of one of his clients, he took the Cirrus Aircraft Advanced Transition course in the modern G1000 glass cockpit Cirrus SR22 G6 airplane. Following that certification, Gutraj has amassed nearly 200 hours in various Cirrus aircraft flying missions all around the continental United States.
With his newly-minted flight instructor certificate, and at the outset of the COVID pandemic, Gutraj decided to take a sabbatical from practicing law and accepted a flight instructor position in the University of Dubuque (UD) Part 141 aviation program. At UD, he instructed a broad spectrum of students from student pilots through multi-engine instructor candidates in the University’s G1000 single engine Cessna Skyhawks and multi-engine Piper Seminoles.

Following the results of a nationwide survey of flight students in 2021 conducted by the Aircraft Owner’s and Pilots Association (AOPA), Gutraj was awarded Distinguished Flight Instructor honors from the AOPA for the Central Southwest region. With more than 100,000 flight instructors nationwide, the AOPA bestowed this honor on the top 100. The award recognizes the highest levels of achievement in the flight training community, with the goal of encouraging others to adopt similar characteristics of success.

Later in 2021, the FAA awarded Gutraj its Gold Seal designation, which is issued to flight instructors who have maintained a high level of flight training activity and who meet special criteria with a proven track record of excellent performance. When he is not flight instructing or practicing law in Illinois, he can be found flying around the country with his rescue dog Shelby in a Cessna 210.

Gutraj also serves as an FAA Safety Team representative and is active in EAA Chapter 327 as a member of its scholarship committee and Young Eagles Flight volunteer. Gutraj credits several other CFIs who have supported him in his journey to become a flight instructor. “The legendary Wisconsin DPE Duffy Gaier and CFI Howard Joling were both instrumental in helping me hone my skills as a commercial pilot and flight instructor applicant,” he said. “University of Dubuque’s chief flight instructor Suzanne Peterson took a leap of faith in hiring a very green instructor with only Part 61 experience from outside the university’s program. Mrs. Peterson has also been extremely patient in mentoring me from a new flight instructor into an Associate Master CFI. Finally, a dear friend, pilot and instructor, Charles Kalvoda, has always been there throughout the past decade offering words of encouragement to support my passion for aviation.”
