I am a FINRA arbitrator and had never noticed the page regarding locating representation. Great service for the Avvo asker.
Another source to find an attorney who specializes in FINRA arbitration claims is the Public Investor Arbitration Bar Association (PIABA) website. This is the bar for attorney's who represent claimant's in securities arbitration claims like yours against broker's and their brokerage firms. The website link is: https://piaba.org/find-attorney
