Zach Hurst, Chief Flight Instructor

AeroTech Services Flight School Flight Instruction Learn to Be A Pilot - Instructor Zach Hurst
I was introduced to aviation on my 8th birthday when I received a joystick and Flight Simulator on a floppy disk! From my first real flight lesson, I had my sights set on a career in aviation as a flight instructor. That dream became reality at Aero-Tech Services, Inc. in 2008 after completing flight training on the windy plains of Kansas at Hesston College. It’s rewarding for me to help someone achieve a goal in flying that they’ve been eagerly working toward. I love instructing because everyday I get to learn something new about the people, the places, and the planes we fly and pass that knowledge on.

 Derlyn Martin, Flight Instructor

Best Flight School Pilot Instruction Lancaster PA
My name is Derlyn and I was born and raised in beautiful Lancaster County!  When I was in my early 20’s I volunteered with an international mission organization that gave me the opportunity to  travel around the world.  Through my travels I noticed a great need for airplanes and pilots to access remote areas that have no road systems.  Upon returning home from that educational experience I soon began my training here at Aero-Tech Services, Inc.  It has been a wonderful journey working from Private Pilot to Commercial Pilot and now Flight Instructor.  During my training at Aero-Tech Services, Inc. I met many wonderful people along the way who shared the same passion as me and they are now serving in places like Brazil, Alaska and Africa!  In Spring of 2016 I became part of the ATS team and I am looking forward to helping others to fulfill their dream of becoming a pilot.  I feel blessed to be able to share the freedom that being a pilot offers with my students and watching their skills grow with each lesson.

Jessica Robinson, Flight Instructor

At the age of 17, I took my first flight lesson in a Bell 47 helicopter hovering over the Lancaster airport. My passion for flying soon led me to obtain my helicopter license and then, through Aero-Tech, my private airplane pilot’s license. Realizing that flying was in my future, I attended LeTourneau University, where I graduated with a B.S. in Aircraft Systems, an A&P mechanics license, and met and married my husband, Andrew. Shortly after graduation, we returned to Pennsylvania, where he accepted a job with ATS as a charter pilot. After the addition of two children to our family and the completion of my commercial and flight instructor ratings in both helicopter and airplane, I also joined ATS in the flight training department. The joy in being an instructor is helping others see their dreams become an attainable goal.

Brian Gulczynski, Flight Instructor

Top Flight School Pilot Instruction Lancaster PA Dalton Wilson

My name is Brian Gulczynski.  As a child, I lived in an area north of BWI airport and my grandfather had a small airplane based in Westminster, MD. The sight and sound of aircraft flying overhead, and the stories told by my grandparents captured my attention and imagination. In 1990 I embarked on my first commercial flight from Baltimore to St. Thomas in the US Virgin Island. Before departing the pilots gave my family a quick tour of the flight deck. Even at a young age I wanted to understand how the engines worked, how wings created lift, and how pilots knew where they were going. After a few years of pursuing less than exciting career possibilities I began to seriously consider my dream of becoming a pilot. In 2011 that dream became a goal when I enrolled at Harrisburg Area Community College. In 2013 I transferred to Utah Valley University online, started flight training locally, and in 2016 completed a B.S. in Aviation Science. Recently I completed CFI training at ATS and started the M.S. in Aeronautics program at Embry-Riddle Worldwide. My objectives as a CFI are to continue developing my aviation skills and knowledge, enhance my communication and teaching abilities, and to help individuals who are enthusiastic about aviation transform their dream flying into the attainable goal of becoming a pilot.


Dalton Wilson, Flight Instructor

My name is Dalton Wilson. I was fortunate to find my love of aviation at 8 years old, when I got to fly with my uncle out west in his jet. I knew from then on, I wanted to be a pilot.  In my senior year of high-school I began taking flight lessons, then continued my path of aviation at Embry-Riddle Aeronautical University in Arizona. After Arizona, I then moved to Florida to complete my instructor certificates and then back to Pennsylvania where my flight career started. The best thing about flying is that every time you are in the air you never complain about the views, especially at sunset. I look forward to helping others achieve their dreams in aviation, as my instructors have done for me.


Chris Bernard, Flight Instructor

Growing up in Lancaster County my first taste of flying was when I was 11 years old after my Father received his Private Pilot Certificate at Smoketown Airport. Since then my brother and I were hooked and after my Father bought his own airplane in the early 2000’s, we would spend countless hours flying all over the Northeast with him. After graduating with a Bachelor of Science in Meteorology from Millersville University, I found that I had graduated into a difficult job market and soon made the decision to follow my passion of working towards a career in aviation. My brother received his Private Pilot Certificate at Aero-Tech Services Inc. so I decided it would be a great place to complete my own training. I’ve completed Private Pilot, Commercial, and CFI training all at Aero-Tech and haven’t regretted it! Flying gives me an immense feeling of freedom and is an experience that can’t be put into words. As an instructor I love that I have the ability to help others achieve their dreams of becoming a pilot, and I hope to be able to share my passion with anyone else who has a love for aviation.


Matt Kauffman, Chief of Operations

As a child I was fascinated with anything motorized, especially with the airplanes that would fly over our house. After my first flight lesson in an Aeronca Champ I knew I wanted to learn how to fly. I did most of my flight training right here at Aero-Tech Services including ATP and Helicopter ratings. I began flying professionally in 1994 and after a short time in corporate aviation and another season as an airline pilot I’ve been flying at Aero-Tech Services since 2000. I appreciate the value that aviation brings to the lives of so many and I enjoy the challenges and adventure of traveling to new destinations. I am thrilled to be a part of helping our customers and employees achieve new milestones in their aviation journey.

Clayton Stoltzfus, Charter Pilot

I was exposed to aviation at a young age when I traveled with my parents to visit mission stations in Central America and Haiti.  I would always stop by the cockpit to visit with the crew and look at the fascinating array of instruments and switches.  I was intrigued by the complexity and power of the airplanes and by the beauty of flight.  As a teenager I joined a few of my friends on a visit to Aero-Tech’s flight school in Smoketown, PA.  I signed up for training and after acquiring my commercial, multi-engine, and CFI ratings I ended up working for ATS as an instructor and charter pilot for several years.  I left the company in 2004 and flew for MAF in Haiti for a little over two years.  After returning to the United States I had the opportunity to build charter and management experience at a few local operations before returning to Aero-Tech Services in 2017.  My goal is to contribute to the team and culture here and help develop the charter program.

Nathan Bagge, Charter Pilot

The ability to bring distant people and places within reach, the opportunity to experience a perspective we’ve had for only a little more than a century, the thrill and satisfaction of operating a unique piece of machinery: these are all reasons many of us enjoy flying and I’m no exception. I was first introduced to airplanes through repeated travel to and from my childhood home in Kenya. As a kid, I loved driving any kind of vehicle I could get my hands on. This and plenty of exposure to airplanes led me to pursue a career in aviation which started with training at Letourneau University. Since then, I’ve worked as a pilot and/or aircraft mechanic in rural Alaska, Washington, Virginia, and now Pennsylvania with Aero-Tech. I love the rewards and challenges flying provides and seeing firsthand how an invention like the airplane can serve both our local and global community.


David Peachey, Chief Helicopter Instructor & Charter Pilot

Best Flight School Pilot Instruction Lancaster PA

I grew up in central Pa. in the small town of Belleville, Pa. My interest in aviation began while living in Danville, Pa and watching the EMS helicopters takeoff and land at Geisinger Medical Center. I thought how cool would it be to fly as a job instead of fix cars, which is what I was doing at the time. I eventually took a discovery flight in a Piper Archer and have been hooked from then on. My ratings currently are: commercial, CFI, CFII- airplane single-engine land, commercial – airplane multi-engine land, and commercial, CFI, CFII – rotorcraft helicopter. I love the variety that aviation offers and the different perspective you get of the world as a pilot. As an instructor I’m committed to providing my students with quality individualized instruction helping them achieve their personal goals. I’m also rewarded by seeing others learn a new skill and begin enjoying aviation as I do.


Amber Lynn, Office Manager

I am the office manager here at ATS. While working as a bank teller in 2007, one of my customers wearing “Top Gun” sunglasses approached me and asked if I would like to try something different. Having no aviation background, I was a little nervous but found the subject challenging and exciting. I have not been disappointed in my decision! On my very first day I practiced the aviation alphabet and have continued to learn more each day. I truly enjoy the relationships I’ve made here and watching people grow as pilots.

Originally from the Midwest, I moved to Lancaster county with my family in 2011 when my husband was hired at Sight and Sound Theater. Along with our two children, we often find ourselves enjoying one of the many local tourist attractions available in the area. One of our favorites is Indian Echo Caverns! Although I am new to the aviation industry I have been working in finance for years! Most of my work may be behind the scenes, but don’t hesitate to say hello if you see me buried under some papers at the office.

I was born in Paoli, Indiana.  Growing up, I would tag along with my dad to the Philadelphia Airport to pick up seafood for the company he worked for.  I remember being so amazed as to how such a large object could soar through the skies.  I took my first flight lesson on my 19th birthday and have been hooked ever since!  I currently fly with ATS, and am working on reaching my personal goal of a career in aviation.
