And the winners are...the doctors of UCSF's Mabuhay Health Center!

This group of renegade health professional students from UCSF and other Bay Area medical schools (all under 40) opened a free clinic last December at Bayanihan Community Center in SoMa. Now they're extending their services to the youth of SF by opening a site at Bessie Carmichael Elementary school in October, which will offer health education and free medical and dental care for students.

They'll be featured in our October Hot 20 Under 40 issue.

Take a look back at who made it through round 1, 2, 3 and 4 and congrats to the doctors at Mabuhay Health Center!
