I would like to highly recommend Halo Business Systems Salesforce.com Admin/App Builder training. I attended a week long tutoring session presented by Ryan Scalf and was thoroughly impressed by his in-depth knowledge of the material and his engaging teaching style. He is completely vested in the success of each of his students. I left that class not only quite confident in the material but felt very prepared to continue my studies, Trailhead exercises and eventually take my certification exam. Anyone looking for a top notch Salesforce instructor or consultant will not have to look any further than Halo Business Systems.
