Don't Sign!!
I was contracted with Massage Envy for years- Their goal is to get you to sign a binding financial contract. The contract price at Massage Envy is the same for other non-contract massage facilities in the area. Why does a massage facility require a contract for a year??? The only answer is money, don't feed them.
That said, I am not taking anything away from the people who have worked there, I have met some dedicated and talented staff, and of course the fresh out of massage school people you avoid. However, the same level of care can be found elsewhere without the contract.
