Our family has attended Fosters Shorin Ryu karate classes for years from 4-years-old up to the 27-year-old mama. What a welcoming, purposeful, loving class and teacher. I can’t recommend Seth enough to have in your life plus the family-oriented business makes it a very comfortable atmosphere.

The new Foster's Fitness facility is incredible. Love the new environment. Also, the owners Seth and Katie Foster are extremely helpful. A must visit when you are in Eureka Montana.

I have been attending this gym for 10 weeks, I can't emphasize enough that this gym is the BEST! Katie and Seth are so personal and keep a friendly atmosphere. Also the cleanest gym I have ever attended, you dont worry about getting on the floor to complete your workout. Thank you Foster's.

My 4 year old goes to karate here. The instructors are amazing with the kids. The gym and facility are nice and always clean. They are opening a new beautiful, larger gym a few blocks over. Conveniently located and offer several classes for adults and children.
