Klein Oak HOSA is an organization for students interested in the health or medical field. HOSA promotes service to the community, and volunteering is a big part of our organization. Members can participate in volunteering events at nursing homes or attend walks that raise awareness for certain diseases, such as Light the Night and Relay for Life. Also, HOSA competition - at area, state, and national levels - gives HOSA members opportunities to expand and use their knowledge in health or medical areas, as well as being able to network and build life-long friendships .
