Our Impact In The Community
Here at Merle Hay Fitness, much of what we have done has been building up our members and the Des Moines community physically. I am very excited to announce that we have now decided to take it one step further and officially partner with Youth Emergency Shelter & Services (YESS) to not only physically heighten the stability, strength, and power of our community, but mentally and emotionally as well.
YESS is a local charity that embodies so much of what we preach to our members whether it is building positive relationships, working as a team, developing life skills, or helping an individual realize their highest potential.
Their mission is to meet the critical needs of the community by providing a full network of quality programs and services designed to keep kids safe and families together. Altogether, 2,245 children utilize this network of services to find safety and caring support.

As Iowa’s largest provider of emergency services for youth, newborn through age 17, YESS provides a range of programs and a is nationally-accredited nonprofit organization that meets the physical, mental and social health needs of children and creates an environment where families can thrive.
By partnering with YESS, we have taken it one step further to not only physically heighten the stability, strength, and power of our community, but mentally and emotionally as well.
Although we at Merle Hay Fitness are not under the same roof – as the caring team at YESS – I believe that we can have a positive impact and add value to the lives of those children and their families in a meaningful and measurable way so that YESS can continue to provide for all the needs of the children and families that receive their support.



If you’re unfamiliar with it, Facebook allows you to “check in” to a local business, letting your friends and family know that you support a particular business. When you use the Facebook check in at Merle Hay Fitness, not only will you show your support for us, but you’ll also be joining other members in their support of YESS.
That’s because every time our clients use the Facebook Check-In feature when they visit, we
will make a contribution to YESS that will benefit the kids they serve.
At Merle Hay Fitness we believe that we can help change the lives of those who can’t help themselves. The life you change may never know your name or be able to thank you, and that’s the grandest part of it all.
