More About Me

Mariliz Vega-Anderson

Healthcare billing is not just my profession — it is part of my legacy.

Atlantea Medical Billing, LLC was founded by my mother with a commitment to integrity, precision, and service. In 2015, I had the privilege of stepping into leadership and continuing the foundation she built, while evolving the company to meet the growing complexities of today’s healthcare reimbursement environment.

​

With over 20 years of experience in medical billing, I have dedicated my career to helping providers navigate Medicare PDGM, Medicaid, behavioral health, pain management, general medicine, and podiatry billing with confidence and compliance. I understand that behind every claim is a provider focused on patient care — and my responsibility is to protect the financial health of their practice with the same level of care.

​

Before leading the company, I worked at Dollar Tree’s corporate office as an Import Account Specialist, managing high-volume accounts and collaborating with international vendors worldwide. That corporate experience strengthened my operational discipline, analytical thinking, and commitment to professional excellence.

​

In addition to healthcare and corporate leadership, my husband and I owned and operated a restaurant together. Running a restaurant required hands-on management, financial oversight, vendor negotiations, staffing leadership, customer service excellence, and the ability to make critical decisions under pressure. That experience sharpened my entrepreneurial resilience and reinforced the importance of accountability, adaptability, and strong client relationships.

​

Today, I lead Atlantea Medical Billing with both professional precision and entrepreneurial strength — honoring my family’s legacy while building sustainable revenue solutions for the future. My leadership is rooted in integrity, shaped by experience, and driven by results.
