I am giving a shout out to Sarah Rogers at Mountainside Fitness. She was super helpful in setting up my membership. Folks, reach out to her for signing up and she is fantastic.

My favorite gym out of a couple different locations I've been to. The gym layout is perfect. Staff is always friendly and the place is always nice and clean.

I would never sign a membership with this gym. I called arrowhead and asked them to stop my membership because I live in Hawaii and the man said I had to write a letter to the corporate office which I did. They sent a text to my daughter.as shown below from Taylor Hunter . My daughter called the number and they were asking her for membership money as our card had expired. I thought when I wrote the letter in April the membership stopped in June. I called Taylor and the corporate to let them know I was never told it now has t... read more

I have had many problems here recently regarding the staff. Recently Danielle has been verbally abusing her staff and the people trying to work out and mind their own business. She has also recently yelled at me and my friend for letting him in the cold plunge so he could test it out and see if he wanted to get one. She threatened to cancel my friends and my own membership.

Kids area is completely out of ratio during summer time from what I have witnessed and the babies just sit in the bouncers/ swings until their parents pick them up. No one is in the baby area attending to them and making sure they are getting time. I have a 10 year old and a 3 month old. They do not have enough staffing!!!! Makes me nervous to take my children, they don't have enough eyes on the children. Don't recommend if you have kiddos. Will not be back.
