Stephanie Spielholz
Event Manager
I’m Stephanie, founder of Core Confidence Club in Yardley, PA. I’ve been teaching group fitness for over ten years and built a space of my own centered around intentional strength and real confidence.
My style is bestie hype girl meets grounded coach. I create small, supportive classes where women feel strong, seen, and capable without pressure or performative energy.
Core Confidence Club is a boutique studio experience focused on empowering women through movement, consistency, and community.
