I love this place! I was new to Crossfit when I walked in their door over 2 years ago. I have learned so much and made great friends in the process. The coaches are so supportive and knowledgeable. If you are looking to challenge yourself and workout with some awesome people, I highly recommend CrossFit 805.
- Kim K.
The coaches Joel, Don and Stacey are the best. They are knowledgeable, helpful, supportive, encouraging and understanding. The people that go there are friendly and supportive. Everyone has a goal and no matter what it is they all have your back.
- Brenda S.
Dropped in unannounced and we felt very welcomed. All movements were explicitly explained and the coach kept an eye on us the whole time- made sure we knew where the running routes were. We were very impressed with the athletes and how welcoming everyone was to some new comers! When we are back visiting, we will stop by again!
