At first glance, it's easy to see how Massage Green Spa helps to improve clients' wellness. The licensed massage therapists ease minds and bodies with custom bodywork sessions, which they enhance with hot stones and aromatherapy. The aestheticians, for their part, dab faces with renewing serums during facials. For further relaxation, infrared saunas help guests unwind, detoxify, and relax. And thanks to memberships that keep pricing competitive, this national network of spas has made fans of everyone from Crain's to the Detroit Tigers, who named Massage Green Spa the team's official therapy clinic.

But the spa's concerns go beyond health and beauty. Massage Green Spa is also committed to reducing its carbon footprint by using eco-friendly building materials in its facilities and incorporating a host of chemical- and preservative-free products into its treatments.
