Medical Practice Mastery

Who We Are
We are Medical Practice Mastery, LLC, a Provider Service Organization founded in 2019 and headquartered in Denton, Texas, deeply rooted in a mission to empower healthcare providers to succeed as independent entrepreneurs. From our inception, our vision has been to create a thriving community of practice owners—physicians, nurses, and clinic leaders—who can learn from one another and grow together. At our core, we are a diverse team of healthcare professionals, educators, and administrative experts united by our commitment to simplifying the business of running a medical practice.

Our leadership brings decades of collective experience to this mission. Our CEO and co‑owner, Rene Lumene, holds dual Masters degrees in Business Administration and Healthcare Administration and carries over 18 years of healthcare leadership experience. Our COO and co‑owner, Christina Lumene, brings financial acumen and a mastery of disciplined budgeting, which ensures our own operations—and our clients’—are guided by sound financial principles. Our administrative team, including professionals like Olivia Matthie, brings a depth of hands‑on expertise in medical billing, insurance coordination, and practice administration, empowering us to offer full‑spectrum support.

What Services We Offer
We deliver a comprehensive suite of services designed to support the full lifecycle of a private medical practice, combining technical know‑how with operational insight. Our revenues cycle management solutions streamline billing workflows and optimize reimbursements by ensuring accurate charge capture, claims scrubbing, and denial management. We oversee claims follow-up and patient billing, with an emphasis on reducing administrative burden and enhancing cash flow while fostering strong patient communication.

In addition, we provide robust credentialing services, managing provider enrollment with commercial insurers, Medicare, Medicaid, and hospitals.

Our healthcare consulting services cover everything from practice startup and strategic planning to accreditation readiness, marketing, financial projections, and staffing support.

Our clients include those in transition—opening new practices, refining operations, or seeking community and mentorship. They are providers who understand that running a successful practice demands more than clinical excellence, and are looking for trusted, experienced partners to guide them in administration, finance, and operations.
