Critical: Professionalism I watched an employee from this company in the work van lay on his horn while tailgating someone that was doing the speed limit. He then aggressively passed them on the shoulder. Van number 0019. Based on that. I would never recommend this company.

I've never used the Hermanson company, but I did get buzzed by their service van doing 70 on the snowy freeway. If their service is anything how they drive, it'll be fast and reckless.

Dude was totally rude. He was leaving a restaurant (with his own kid) and didn't even hold the door open for a lady coming in with a stroller.
