My daughter asked the tech to stop what she was doing because she was pinching her but she continued subsequently cutting her lip and swelling occurred. Tech was frustrated as she could be heard through her mask sighing heavily. AS my daughter got up from the chair the tech expressed to the STVT student that, "he was lucky he was leaving" as she wanted to leave as well. We would prefer to have our daughter seen by a more experienced tech the next time we go. We are not disappointed with RGV Smiles, but we are disappointed with the tech.
