5 out of 5 stars

Without a doubt the best place to workout. This isn't a crossfit gym. At Essers you get a concentrated personalized workout without the private personal trainer price tag. Kasey and his staff know their stuff & with the recent addition of Sofia Costa PT, DPT, CES it truly is the only place to achieve whatever physical goals you may have. A total no nonsense facility with a fresh personal approach. I'm stunned that there aren't more facilities like Essers.
