Personal Philosophy

Rosie was inspired to form a career in health and fitness for two reasons: 1) fascination for the capabilities of the human body to overcome what sometimes seems impossible, 2) gratefulness for the health benefits she has reaped by her own physical health. With anyone she treats, she will spend ample time getting to know their preferences and clarifying her treatments, ensuring that her patients and clients are on the path that is right for them.​
