Leonard Mast | Mast Service Center

Leonard Mast

Leonard Mast is the proud owner of Mast Service Center in Etna Green; while he was still in middle school, he anointed himself himself a diesel mechanic and started working on the diesel engines that were on the family farm. After many years and much more auto repair education, his first auto mechanic job was performing fleet service for diesels operating all over the U.S. for about 10 years. 

In 2005, Leonard went out on his own, and Mast Service Center was born in Etna Green, and we have steadily expanded our team for auto repair and fleet services. With our mobile services unit, we can get a diesel mechanic to you if you’ve broken down on the side of the road. Leonard still does plenty of auto repair himself, but has also built up a team of excellent auto and diesel mechanics. Between them, there’s no auto repair or fleet service task that’s too difficult for Mast Service Center. Meet the team below:
