The DCDAA has a new name and logo! The Coalition will now go by Dedham Organization for Substance Awareness, or DOSA for short! Our new logo is pictured above. A BIG thank you to the students at DHS who submitted a design. Name by Vivian Boudette design by Victoria Horard.

  • Increase awareness of substance use within the community,
  • Improve communication between parents, youth, and educators,
  • Utilize evidence-based data to promote education, and
  • Encourage prevention and provide access to resources

The mission statement of the DOSA is to reduce and prevent youth (and adult) substance use by increasing community collaboration and by utilizing evidence based prevention strategies.
