We are pleased to continue our involvement and support of these vital organizations:

firebird fund

As a thank you to their employees, Mountainside Fitness has established the new “Firebird” Fund Employee Assistance Program to help employees during these difficult times.

With much uncertainty and instability as a result of COVID-19, Mountainside Fitness created the new “Firebird” Fund to help provide relief to keep their employees healthy and strong. The program will be used to assist any Mountainside Fitness employee with a need in one of five (5) categories including financial, medical, meals, paid-time off or childcare. Every employee is eligible to request assistance.

The program will be overseen and governed by nine board members coming from the fitness clubs. No corporate office employee will be eligible to serve on the board. This committee will determine disbursement of funds to employee request as well as oversee fundraisers.
