At Greenbrook Medical, we believe seniors deserve more from the healthcare system—more time, more care, more coordination, and more heart. We provide high-touch, relationship-based primary care to seniors, built around one simple idea: deliver the kind of care we’d want for our own parents. Founded by two brothers inspired by their father’s pioneering work in Medicare Advantage, Greenbrook is deeply personal and proudly modern.

We quarterback our patients through their healthcare journey, making sure they’re never alone in a complex system. Our business model is designed around patient outcomes, not volume—so we only succeed when our patients thrive. With roots in Tampa Bay and a partnership with Tampa General Hospital, we’re growing thoughtfully to bring our model to more communities. Our team is the heart of it all: mission-driven, values-oriented, and relentlessly committed to taking the best care of our patients.

As a Medical Billing Specialist at Greenbrook Medical, you will play a key role in managing accurate, efficient, and compliant billing operations. You’ll be the subject matter expert on all things billing — processing encounter data, submitting claims, and resolving billing issues quickly and effectively. This is a detail-oriented and collaborative role that combines analytical precision with proactive problem-solving. You’ll work cross-functionally with clinical, administrative, and finance teams to ensure every encounter is billed correctly and every patient record is complete, supporting Greenbrook’s mission to provide exceptional, coordinated care for seniors.

Compensation range: $21-$23 per hour with a generous annual performance bonus. At Greenbrook Medical, we value fair and equitable pay. Your salary within this range will be based on your relevant, transferable experience and professional achievements.
