Brook is a diverse bunch - clinicians, designers, developers, and entrepreneurs - determined to change healthcare for good.

Our vision

Brook was built on the vision that each of us should be empowered to own our health. So we combine healthcare expertise with cutting edge technology to provide knowledge and insights that help our users make smarter, daily decisions.

Our business

Brook collaborates with all the providers that help manage a patient’s health: physicians, insurance companies, employers, and technology suppliers. We generate patient health reports that make for better doctor’s visits, make it easy to sync our system with a patient’s devices, and mostly importantly, help people stay healthy – so they can be their best selves at work, at home and wherever life takes them.

"We believe positive ownership of health starts today. That’s why we created Brook."

I love going for early morning runs, watching the sun rise over the city from Ballast Point Park.
