Verve is a small studio, but their classes are quality. During the summer I signed up for unlimited classes and have cycled through most of the instructors. Each one has their own style but I can say that every one of them is patient, down to earth, and experienced. The playlists in the classes are also amazing, I definitely can go from having a sense of serenity to kicking butt on my reformer depending on the song- absolutely wish I could just take it home with me. I've tried a ton of other pilates studios in Phoenix and this one is my favorite; I've been doing pilates for a few months now and still feel like a beginner, but the welcoming environment keeps me coming back.
