Meet Sara

MS | RD | CSSD | LD | acsm-cpt

Hi, I'm Sara Arnold, the founder of KC Performance Nutrition. As a sports dietitian and former multi-sport athlete, I'm passionate about helping athletes like you reach your full potential. My expertise focuses on performance nutrition while also addressing disordered eating, eating disorders, under fueling, and Relative Energy Deficiency in Sport (REDs). I understand the unique pressures athletes face, and I combine my expertise with empathy to provide evidence-based strategies that enhance both your physical performance and mental resilience. 


My approach goes beyond traditional nutrition counseling. I'm here to help you build a supportive and empowering relationship with your body, food, and movement. My mission is to ensure you feel confident in yourself - both on and off the field.
