I honestly can't recall if there was a formal mentor program. However, your supervisors, branch mangers, and area managers will do what they can to help you. Part of getting promoted as an Assistant Branch Manager to Branch Manager is making sure your people are able to get promoted and that they are successful in all areas of the business. Mentoring is something Enterprise does well, even though I can't remember if they have an official program, and if I ever needed feedback on anything, those in charge of me were always great at taking time to help me even on the busiest of days. For all the critiques I have towards Enterprise, this is not one of them.
