The Hidden Gem - Sulphur Springs Jordan Potts: The Hidden Gem in Sulphur Springs, TX is wonderful! They offer a variety of classes including Pilates, yoga, strength training, beat boxing and more! Their infrared classes make you sweat but you feel so good afterwards. It’s been great for joint pain and inflammation. Very welcoming environment and fun classes. Highly recommend trying it out! The new owner, Maddie, is the sweetest and really pours her heart and soul into The Hidden Gem.
