Our Story

We function as a family, creating a unique synergy that drives our custom wellness programs.


Hello! My name is Kelsey, and I am the Owner and CEO of Pro Fit. My calling is to educate and empower others to take control of their health. Twelve years ago, I was struggling with PTSD, gut issues, autoimmune thyroid disease, and metabolic dysfunction. As a single mom with nothing but a blow-up mattress and an empty apartment, I knew there had to be a better way to heal—so I set out to create the comprehensive, science-driven approach that I desperately needed at the time. In 2013, I pursued certification in Functional Medicine, which led me to earn my Master’s in Functional Medicine and Clinical Nutrition. That journey of self-healing and education laid the foundation for what is now Pro Fit, a company dedicated to helping others reclaim their health and performance.

Utilizing lab testing and scientific-based assessments, we develop protocols that put YOU in control of your health. Together, we identify root causes, genetic risks, and metabolic barriers to build a plan that aligns with your goals and lifestyle—whether that’s fat loss, hormone optimization, or overall longevity.

Every program, supplement, or lab test we recommend is backed by research and clinical data. The nutrition and wellness field is constantly evolving, and we make it a priority to adapt, improve, and refine our programs as new, proven methods become available. By working with us, you receive the most up-to-date, clinically proven protocols in the industry. For complex cases, we collaborate with a Board of Directors, mentors, and medical practitioners to ensure you receive the best possible care. And if we aren’t the right fit, we’ll always be upfront and connect you with someone who can better serve you.I built Pro Fit from the ground up—now, let’s build the healthiest version of you.
