Bruce Evans, M.D.


Dr. Evans is an Emergency Medicine physician with Kaiser and Saint Joseph Hospital.  He is a skier and snow-border who has seen, first-hand, how helmets save lives.  His interest in helmets and head injuries dates back to his days as a professional ski patroller.  As a teacher at the CU School of Medicine, he developed an evidenced-based review on the important benefits of safety helmets back in 2004; "Helmet Heads" was born!  Since that time, Dr. Evans, who was teaching Emergency Medicine as an Associate Professor at the University of Colorado when he developed the program, has helped Helmet Heads deliver over ten thousand bike/skate helmets to kids in the poorest communities across Denver-Metro front range.  He is pragmatic about Helmet Heads; he believes that saving even one child from a serious head injury will more than justify the efforts of the non-profit and all-volunteer team that makes up Helmet Heads.  Dr. Evans skis Mary Jane and Arapahoe Basin with his kids with his kids every chance he gets, and they always wear their ski helmets!
