Great Expressions Dental Centers review: Hygienist has covid

I had an appointment today at great expressions in Dublin, it got canceled due to their hygienist having COVID-19 but my daughters appointment was still on going, we show up they ask if we've been exposed to COVID-19 which our answer is no, but that whole office was exposed to COVID-19 due to their hygienist, why is this place open still if their workers have been exposed? I do not want any of my children coming back here when they clearly do not care about patient health.
