I went to Dr. Gregory-Head for an expert opinion on my crowns. She is a well-regarded expert in Prosthedontics and teaches at University. I find her manner to be very smooth, confident and professional. One issue I have is that she is not a Preferred Provider for my dental insurance, so going to her is much more expensive for me. So for routine procedures, I am going to another dentist. But for crowns, etc. she is the expert and definitely worth the extra cost.
