Our Story
Trevelin Partners was created by Greg Serrao, an entrepreneur who spent his career building, scaling, and leading healthcare organizations. After founding and growing several national companies, and experiencing both the challenges and rewards of entrepreneurship firsthand, Greg launched Trevelin Partners to support the next generation of healthcare innovators.
What differentiates Trevelin Partners is not just capital. It’s the perspective of someone who has been in the operator’s seat, navigated complex healthcare environments, and built organizations that lasted.
Trevelin Partners exists to give founders a partner who understands what they’re building because he has built it himself.

Committed to Healthcare Entrepreneurs
Throughout his career, Greg saw the same pattern repeatedly:
- Great entrepreneurs with strong ideas
- Mission-driven companies improving care
- Teams ready to grow
- But limited by undercapitalization, trial-and-error decision making, or lack of experienced support
Trevelin Partners was founded to fill that gap, offering strategic capital, operational mentorship, and a trusted partner who shares a founder’s mindset.
Our mission is simple: support entrepreneurs improving access to healthcare and help them build organizations capable of meaningful, lasting impact.
Our Philosophy
Entrepreneurs deserve more than capital. They deserve a partner who:
- Understands their challenges
- Has scaled healthcare businesses themselves
- Provides honest guidance
- Helps avoid unnecessary mistakes
- Brings conviction and alignment to the table
Trevelin Partners invests selectively so we can remain deeply engaged, offering mentorship, strategic input, and practical support that helps founders grow faster and more confidently.
We partner with entrepreneurs who are advancing healthcare by improving access, elevating outcomes, and building organizations that make a meaningful difference in people’s lives.
