Frequently asked questions
What is the relationship between Greentree and Flying Doctors?
Dr. Brown founded Flying Doctors Healthcare Investment Group alongside her work at Greentree. The two entities share a capital pipeline: Greentree has channeled investment into health-infrastructure assets, including an air-ambulance fleet, that sit under the Flying Doctors umbrella. The degree of legal separation between the two is not publicly detailed, but operational personnel overlap is clear from public record.
What sectors does Greentree explicitly avoid?
Greentree does not publish an exclusion list, but its observable portfolio — enterprise software, fintech, digital health, media — omits heavy infrastructure, extractive industries, and real estate development. The firm's intellectual roots are in services and technology adoption, not physical asset deployment. This pattern mirrors the co-founders' own operating backgrounds in healthcare, marketing technology, and credit analysis.
