I became a patient of Dr. Thomas's when he bought the practice from my retiring dentist.I arrived to an appointment (Kirkland office) where I was to have an existing crown replaced and once I was seated, bib in place, the assistant who has a heavy accent told me that someone (couldn't understand) would be over to to something (couldn't understand). I asked her to repeat it and again didn't understand. So as not to appear rude by asking her to repeat herself again, I simply figured I'd know soon enough when whoever showed up to do whatever. To make a very long and very upsetting story short. The who was Dr. T's sister who had just days earlier graduated from dental school. This information was not offered to me at the time btw. I was presented to her so that she could gain some practical experience...at my expense and without my permission. What followed was the worst experience I've ever had at any medical appointment, and at no time did Dr. T step in to take over. I now have sensitivity with that tooth. When Dr. T was made aware that I was upset about the treatment I received, he had his office manager call to tell me essentially, too bad. Everyone makes mistakes. Dr. T needs to accept accountability for his.
