CURRENT:

After work, Doctor Christopher Duma trades in his surgical instruments for musical ones.

As front-man for the band Circle of Willis, his stage performances are music to the ears of his patients. You see, Duma uses the band to raise money for the patients in Hoag Memorial Hospital Presbyterian, where he works.

This Friday, Duma and his band mates (all of whom are doctors) will come to the aid of 14-year-old Austen Landaas, who suffers from a rare form of leukemia called Acute Myelogenous Leukemia. The benefit concert will begin at 7:30 p.m. on Friday at the Friends Sports Tavern, 31911 Dove Canyon Drive, Trabuco Canyon.

The Circle of Willis will be playing hits from the 1970s, 1980s and 1990s. Check back soon for more details.
