I had the best testing experience at this location compared to 12801 N Central Expy #820. The staff and especially the African American lady who took me into the room wished me good luck compared to the lady at 12801 N Central Expy #820 who was plain rude, rolled her eyes at me and acted as if I was inconveniencing her by being there. If you are testing in Dallas go to this location you will not regret it.
