Buffy is fully certified by Karen Sanzo's Pilates Unlimited program, which is approved by the Pilates Method Alliance. She sees Pilates as her gateway to fitness after being unenthused by many other types of exercise. Buffy began Core Essentials in 2004 as a mobile Pilates company, before planting roots in Avondale in 2005 in order to offer a completely equipped Pilates studio to her clients. Seeing her clients progress and helping them get in touch with their bodies is her favorite part of teaching.
