Website is awful for any information. No information on pricing and limited information on what facilities are available and no photos of the actual gym. Maybe I'd like to see some photos of the pool or gym before I waste my time coming it to get the sales pitch on some kid pretending to be a personal trainer. I shouldnt have to enter all my information to see what the gym looks like.

Communication with management is not timely. I have been trying to reach Wyatt (General Manager) since April 12 and am receiving very minimal communication back.

Have been going here for a few months. As long as your not handicapped it is cool. They wouldn't let me use the handicapped chair to enter or use the pool. They rent out that lane all weekend so handicapped or people recovering from injuries ect cannot have access to the pool. Even thought there were plenty of lanes open they rent that lane to deny access to people with mobility impairments.

I've been a member of this outstanding club for many years and greatly enjoy the high quality facilities, broad range of activities, professional & knowledgeable training staff, and friendly atmosphere!
No, it is not cheap. But you truly get more than you pay for and won't regret the investment - just like you never regret the investment of time devoted to fitness!

Still super filthy. Why is this so hard to correct? Management needs a major overhaul
