Controller

About the Role

Greenbrook Medical is building the new standard in primary care, delivering high-touch, relationship-based care through neighborhood clinics grounded in the belief that every senior deserves the kind of care we would want for our own families. The model prioritizes time with patients, strong care coordination, and a personalized approach that improves outcomes while lowering total cost of care. Greenbrook takes full accountability for patient outcomes and overall cost of care, aligning clinical excellence with disciplined execution, reflected in a patient Net Promoter Score of 90 compared to 32 for typical healthcare organizations. Rooted in Tampa Bay and partnered with Tampa General Hospital, the company is entering an exciting phase of growth backed by strong unit economics, experienced operators, and a proven playbook.

As Controller, you will own Greenbrook Medical's end-to-end accounting function and build the financial foundation that enables the company to scale. This is not a traditional accounting role focused only on closing the books. You will be accountable for the integrity of financial reporting and own the systems, processes, and controls that support accounting operations, financial compliance, and continued growth. Reporting to the VP of Finance, you will lead core accounting operations, including the close and financial reporting processes, while strengthening the financial infrastructure needed to support a fast-growing, multi-clinic healthcare organization. You will partner across the organization to bring order to complexity, improve operations, and ensure leaders have accurate and reliable financial information to make better decisions. This role is ideal for a hands-on builder who can dive into details, create scalable processes, and elevate a finance function from good to great.
