Pinnacle is amazing. The background checks are thorough, reliable, and quick. Their interface is super easy to use to request new background checks and view the results. I use Pinnacle for background checks on ALL of my employees. Dealing with sensitive data I have to make sure the people I am employing are qualified and trustworthy. Pinnacle helps me in doing so.
