If I could give 0 I would. I had a cleaning a crown done (they told me i needed it) and have experienced pain ever since (10 months ago). They referred me to a specialist in their network who was so unprofessional I doubt he is an actual doctor. And despite lodging many calm complaints and trying to see what could be done they did nothing, except continue to email and call me to tell me to come back for another cleaning etc...
These fly by night spots are why many of us have serious reservations about going to health care providers.
