Last year 15 members of the OI medical community did something very special. They walked 50 miles over 3 days to raise awareness for OI. And now, they are doing it again! Kick-off National OI Awareness Week and celebrate 50 years of the OI Foundation with ten of the dedicated members of the OI medical community as they march their way around the Washington, DC metro area to raise awareness and funds for the OI Foundation!
