  • Stephanie Happe
    Corrective Exercise & Foundation Training

    Stephanie Happe comes from a background in Dietetics but quickly found her passion working with special population exercise programs in 2011. Beginning with Stanford's Living Strong, Living Well, a program designed for those recovering from cancer treatment, she discovered that working with this group was challenging yet immensely rewarding.

    She began to focus on adaptive exercises for those with movement dysfunction due to chronic diseases. This path quickly lead to her involvement with many other special populations including those with arthritis, diabetes, dementia, auto-immune diseases, balance difficulties, and weight concerns.

    She believes proper posture, good balance, and a strong core are the building blocks of any effective fitness routine. Her goal is to create fun and effective programs to correct imbalances, help relieve chronic pain, and get you back to what you love to do!

She also holds a certification in TRX training.  After living in Italy and teaching English for over 12 years, she has returned to California, settling in the South Bay Area with her family.

Motivating and encouraging people to find joy in movement is her greatest pleasure.
