Controller, Accounting, Financial Reporting

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: every senior deserves the kind of care we would want for our own families. Our model prioritizes time with patients, strong care 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. That commitment shows up in our results, including a patient Net Promoter Score of 90, compared to 32 for typical healthcare organizations.

Rooted in Tampa Bay and partnered with Tampa General Hospital, we are entering an exciting phase of growth. Backed by strong unit economics, experienced operators, and a proven playbook, we are looking for builders and operators who want to help scale a healthcare platform designed to deliver better care, better coordination, and better outcomes for seniors.

About the Role

As our 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 our financial reporting and own the systems, processes, and controls that support our 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 how we operate, and ensure leaders have accurate and reliable financial information to make better decisions.

This role is ideal for someone who enjoys being a hands-on builder: someone who can dive into the details, create scalable processes, and elevate a finance function from good to great.

Location: New York City or Chicago preferred (Hybrid). Open to remote candidates.
