Thatcher Keast joined the RM Sotheby's Group as a Car Specialist in 2015 shortly after graduating from Kansas State University with a Bachelor of Science in Business Marketing. Thatcher began working in the automotive industry at just 14 years old when he started his own automotive detailing business in Salina, Kansas. He soon found a mentor in local car collector Roger Morrison and became responsible for maintaining his diverse collection of automobiles, including Shelbys, Porsches, and Brass Era Rolls-Royces. What started as a summer business venture nurtured a strong appreciation for a broad spectrum of collector cars, as well as what it means to maintain a significant piece of automotive history, and further developed his passion for the industry. Thatcher has a special interest in Shelby Cobras and Mustangs, German performance cars, and modern supercars and is a member of several enthusiast clubs, including the BMW Car Club of America, the Mercedes-Benz Club of America, and the Antique Automobile Club of America. 

In 2019, Thatcher assumed the position of Consignment Department Manager and Auction Coordinator, where he oversees consignments and the logistics of making an auction come to life. In 2022, he attended The World Wide College of Auctioneering, where he gained the skills needed to sell cars crossing the block at auction. He is now a licensed auctioneer, a great addition to the RM Sotheby’s roster.
