Our Story

A Mission Built on Integrity and Innovation

In 2010, Kelly McCarthy—a seasoned entrepreneur—founded Medinex Healthcare Solutions in Celebration, Florida. After leading her own successful practices, Celebration Pediatrics and Celebration Obstetrics & Gynecology, she experienced firsthand the frustrations of medical billing inefficiencies: delayed reimbursements, claim denials, and administrative overload.

Determined to find a better way, Kelly established Medinex with a mission to transform medical billing from a burden into a strategic advantage. By combining real-world clinical insight with operational expertise, Medinex empowers healthcare providers to streamline revenue cycles, strengthen financial performance, and refocus on patient care.

Kelly’s leadership shines through in every client relationship. “I’ve been where you are,” she often tells new partners. “Overwhelmed by the ‘business’ of medicine yet committed to excellence in care.”

Today, Medinex stands as a trusted ally to providers across a wide range of specialties—earning a reputation for integrity, transparency, and measurable results.
