  • "My last appointment was a doozy: extraction of a deeply infected molar. High anxiety and tension. Doctor and his assistant were very patient with me; checked in with me frequently, explained everyas we went, adjusted numbing levels, took additional breaks when I requested, encouraged me. I felt heard and seen. That level of care made the best of this difficult experience and I’m very grateful. And one day post-procedure I feel great!"
