Meet Your Hosts

Glenn Soffner

The campers are what make this job enjoyable. We all share a passion to be outdoors, making memories with our families and friends.

We are so excited to welcome Glenn Soffner as the new host of Thompson KOA!

After 25 years of working as an Auto Body Technician in California and Hawaii, Glenn decided he wanted to explore more of the US. Glenn, his wife and their dogs started living full time in their RV and traveling around the country. He started working for KOA in 2013 and has managed campgrounds in California, Kentucky and Florida. He's excited to now welcome campers from near and far to the Thompson/Grand River KOA!
