How we ranked them
The Handshake Score rates each company’s whole western US operation from sourced public records: customer reviews, BBB complaints, contract terms and sales practices, licensing, and the legal and regulatory record. It isn’t a score for the branches in this area alone.
A location on file means our research found a branch or listing there. It doesn’t show which addresses a company serves; check with the company.
