Controller

About the role

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.
