You can search for attorney representatives by geographical location on , and also at the link I put below. But as Mr. Studdard wrote, you don't need a local attorney to handle your claim, and there are so few who focus on VA disability that you're probably better off doing a nationwide search.
As was mentioned, you don't actually need a lawyer in your area. VA claims are federal, they do not involve working in any state legal system...so you can have a lawyer in Alaska working on your claim if you wished. I did want to point out that any lawyer you select needs to be accredited by the VA, and that is an obnoxiously time consuming process right now (months long)...so you want to find someone that is already accredited. VA keeps a database that you can check here: http://www.va.gov/ogc/apps/accreditation/ . I would recommend using a combination of and checking names in that database.
