"The hiring process for law enforcement positions is daunting! I made lots of mistakes and I wasted a lot of time. I searched high and low for background experts and this led to eventually meeting Ken Roybal. I met Ken while I was in the hiring process for the LAPD. His insight into the process was invaluable! He was able to explain the behind the scenes work done in personnel and this gave me a clear road map as to what I needed to do if I wanted to get hired with LAPD, or other agencies."
