WOW! Even drove me so i would not get rained on!

August 28, 2017
By Hausy from Sioux City, Iowa

Everyone was so friendly-even the process of making the appointment! I was greeted by nearly ever person in the service area. They even drove me to my hair appointment so I did not have to walk over in the rain. And picked me up afterwards! Could not be happier with the service I got that day!
