Complex Exposure Threats Center (CETC)


  • The CETC team of clinicians and scientists are responsive to Veteran concerns by evolving, innovating, and tailoring our clinical and research services to meet the rising challenges of exposure-informed care. The team also is dedicated to ensuring effective coordination and collaboration of efforts both within and outside the VA by engaging key external collaborators and academic institutions.
