Veterans Service Officers

When you need assistance getting the benefits due as a Veteran or eligible family member you should seek the assistance of a Veterans Service Officer (VSO). A VSO representative can help you gather evidence needed and submit a Fully Developed Claim on your behalf. A VSO representative can also correspond with the Department of Veterans Affairs (VA) about your claim on your behalf. VSOs always provide their representation on VA claims free of charge.

VSOs can assist Veterans and their families in many ways, including:

  • answering questions, advising, and educating individuals and groups on what benefits are available from federal, state, county, and local resources,
  • assisting persons in completing and filing benefit claims, and
