Meet Tim Koster


I'm Tim,

My wife calls me Captain Stihl, so as all good husbands know, I best take on the alter ego~


After farming most of my life with Dad and Grandpa Koster and logging over 16,000 hours as a commercial jet pilot/ flight instructor, I'm retiring from corporate America. Today, I instill my high standard of maintenance and meticulous attention to detail into Throttle & Hum, a professional service & sales shop (showcasing Stihl exclusively) on Main Street in Grand Ridge, IL

Drop in and let us know how we can serve your needs~
