Help Us Reach our Goal

In order to continue serving our military personnel, police officers, firefighters, emergency medical technicians, emergency room personnel and other first responders, OSA has started the First Responder Scholarship Fund (FRSF). FRSF will be solely funded by donations from you and other individuals and groups that believe in the work OSA does.

Your donations to FRSF will help provide free care and reduced fee treatment to first responders who would not otherwise be able to receive these services in a timely manner.
