About Us

Tim Ashenfelter started ASI-Aero Services in 1983 which was the company's first exposure to Aircraft Sales. We sold Used piston singles and twins, then eventually became Dealers for Mooney and Piper Aircraft a few years later.  In 1991 we became a TBM-700 Sales Affiliate and the very first TBM Service Center in the US. In 1996 we became a Cessna Caravan Area Sales Rep. We have specialized in the sale of New and Used Caravans and especially Caravan Amphibians over the years.  Again in 1996 we sold our very first NEW Jet, a 1996 Citation CJ. From then on we sold more and more New and Used Citation Jet Aircraft, specializing in all the Cessna Citation models. In 1997 ASI became a Single Engine Cessna dealer and had a very successful Cessna Flight training school that had over 10 Cessna aircraft for rental!  Tom Ashenfelter (Tim's Son) joined the company in 1999 at 16 years old, starting at the bottom as a line Technician, then eventually a part of the Aircraft Sales team in 2007.  In 2001 We became one of the first Diamond Aircraft Dealers where we exceled in introducing the different Diamond Aircraft models to the consumer market.   In 2009, ASI Jet became a Factory Authorized Thrush Aircraft Dealer, Service Center, and Parts Support Center. Successfully buying and Selling New and Used Thrush Aircraft has allowed us to broaden our aviation background to include Aerial Application aircraft, while keeping our roots in Business and General aviation too. 

As a Father & Son team, we have over 40 Years of combined Aircraft Sales experience. So if you are looking for that right airplane for your needs we know how to find it, as well as negotiate purchase contracts, manage the entire Pre-Buy inspection process. We can help you with Aircraft Insurance, Financing, Tax Benefits and Planning, Aircraft Management, Maintenance, and when it’s time to sell, or Trade-Up we can handle those Transactions as well.

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. We had a 1943 North American SNJ-4 since 1970 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 was great training for me.

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 a 1967 Mooney Executive in 1979. Then upgraded to a B58 Baron in 1981.  The passion to fly for business then led me to start ASI-Aero Services in 1983.  In 1981 I rec’d. both my Instrument Rating and then my Multi-Engine rating. 1991 was my first Turbine Flight experience with the TBM-700. Currently I have over 1,500 hours experience in Single Engine Turbine Aircraft including about 250 hours Turbine Sea (Float Plane rating and Caravan Amphibian in 1997). Then also in 1996 I sold a brand new 1996 CJ. And 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.  And with over 32 years experience in Aircraft Sales, I personally have made hundreds of successful sales transactions over that time.

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, and camping. I also enjoy riding my motorcycle(s). Fixing and restoring vintage cars, boats, and motorcycles. I continue to stay as active as possible by playing a little 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 child with my father Tim 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. 

Aviation runs in our Family!
