“Brennan & Co was here today, and I think they are just fantastic, not to mention outstanding! So enthusiastic, energized, courteous, aim-to-please attitude, AND my windows are spotless! I am beyond impressed! You did well to hire and train your crew. I think training is a big part of any job, and they obviously are trained–so rare these days”
