Tim Ashenfelter - President 

About Me: I was born in Minneapolis. Since I was very young I have been Flying with my Father. He was a Private Pilot and as a family we flew C-172’s and C-182’s all over the country. We had a C-180 on floats in front of our house on Lake Minnetonka, then my Dad became interested in War Birds. He owned a 1943 North American SNJ-4 (pictured below) as well as a Stearman bi-plane.

By Education I graduated from Cal Poly in San Luis Obispo, California with a BS in Mechanical Engineering. I received my Private Pilot license prior to graduating San Mateo High School and learning to fly at San Carlos airport in California.

Later I worked as a “Sales Engineer” in the Temperature Control business, then for Cummins Diesel, and finally as Sales Manager of RMS a large local Construction Equipment Dealer.  Always trying to use my Flying in these jobs, I bought my first airplane in 1979; a 1967 Mooney Executive. Then upgraded to a B-58 Baron in 1981. In 1981 I rec’d. both my Instrument Rating and then my Multi-Engine rating. The passion to fly for business then led me to start ASI-Aero Services in 1983. 1991 was my first Turbine Flight experience with the TBM-700. Currently I have over 1,700 hours experience in Single Engine Turbine Aircraft including about 250 hours Turbine Sea (Float Plane rating and Caravan Amphibian in 1997). Then also because we were getting more and more involved with Jets, I received my single pilot Citation Jet Type rating in 2000.

Today I have over 5,000 hours Total Time in pretty much everything piston, Turbine, Citation Jet aircraft, and over 200 hours in the 1943 North American SNJ-4 my father owned.  And with over 34 years experience in Aircraft Sales, I personally have made hundreds of successful sales transactions over that time.


Tom Ashenfelter - Vice President

About Me: I was born and raised in Minneapolis, MN and the surrounding areas. I have a wide variety of interests including but not limited to; Snow skiing, snowboarding, wakeboarding, SCUBA diving, hiking, camping, and of course Flying!  Driving, Fixing, and restoring vintage cars, boats, and motorcycles. I continue to stay as active as possible by playing a little ice hockey, broomball, volleyball, and softball when ever I get the chance. I also am a very big fan of sports and love watching my local Minnesota high school, collegiate, and professional sports teams all year round!

I started flying when I was just a kid with my father and his father (my Grandpa) Bruce. Ever since I can remember I have been interested and passionate about flying. It wasn’t until I got to high school that I realized I wanted to sell airplanes for a living, just like my father. I always wanted to have a career that I could really sink my teeth into and enjoy for the rest of my life. I started working on the flight line when I was 16 years old; refueling, cleaning, and towing aircraft part time while going to high school. When I was 18 years old I began flight training. I finished up my private pilot training and received my ticket when I was 19 years old after my first year of college at the University of Montana. After graduating from the University of St. Thomas in 2006 with a bachelor's degree in Marketing and Business, I started as a salesperson for a motorsports company focusing on motorcycle sales to gain some sales experience. After about 1 year away from aviation, I was eager to get back into it. When the opportunity came up to re-join my father’s company full time in the aircraft sales department, I immediately accepted the position of Marketing coordinator/sales assistant. I learned a lot in that first year in the sales assistant position. Then in early 2008, I was promoted to a full time aircraft sales position. I am still continuing my aviation education and over the last few years I have been training and studying toward more advanced ratings.
