Pre/Postnatal Performance Training Specialist

A mom of two, with her own Cesarean recovery story, Leah’s goal is to educate and empower women on their own wellness journey both pre and postnatal. In her professional life, she has worked with all ages and stages, from kids to seniors, beginners to athletes on implementing small steps to progress clients towards sustainable healthy habits, whether in movement or mindset.

Movement has always been a way for Leah to express and release emotion, challenge herself and grow both physically and mentally. This led her to a BA in Physical Education & Health Education while playing collegiate volleyball, Certification as a NASM Personal Trainer, specializations in Boxing Instruction, TRX Suspension Training, and focuses in Meditation and Self-Myofascial Release. Her passion project of becoming a Pre/Postnatal Performance Training Specialist started when her oldest son was born in 2013.

She lives in Grand Rapids, MI with her family. Outside of the gym she enjoys escaping outdoors, globetrotting with her husband, crafting with her sisters and cuddling up with a good book and a snuggly kiddo or two.
