Controller

About Us

Greenbrook Medical is building the new standard in primary care. We deliver high-touch, relationship-based care through neighborhood clinics, grounded in a simple belief that every senior deserves the kind of care we would want for our own families. Our model emphasizes time with patients, coordination, and a personalized approach that improves outcomes while lowering total cost of care.

We take full accountability for patient outcomes and overall cost of care, aligning clinical excellence with disciplined execution. The results speak for themselves, with a patient Net Promoter Score of 91 compared to 32 for typical healthcare organizations, reflecting our belief that happier patients are healthier patients.

Rooted in Tampa Bay, our partnership with Tampa General Hospital has supported our growth as we expand across the region. Backed by strong unit economics, experienced operators, and a clear playbook, Greenbrook is entering its next phase of growth. We are looking for builders and operators who want to help scale a platform designed to deliver better care, better coordination, and better outcomes for seniors.

 

About the Role

As our Controller, you will be the financial backbone of a fast-scaling, multi-clinic healthcare organization. This is a hands-on leadership role where you will build and own the accounting and financial operations infrastructure that supports everything we do in the field. You will report to our Vice President of Finance, serving as a trusted partner responsible for ensuring financial accuracy, operational control, and scalable systems as we expand.

This is not a back-office reporting role, it is a build-and-scale leadership role. You will upgrade and build upon the financial foundation that allows our clinicians, operators, and leaders to move faster with confidence. You will also work closely with our VP of Finance to ensure seamless alignment between financial strategy and operational execution, but your core focus is building a world-class financial operating system.

If you enjoy bringing order to complexity, building systems that last, and making sure every dollar in a growing organization is accounted for and well-managed, this role is for you.
