I am one of those clients who tends to panic at the dentist but Dr. Jefferies, and his staff, are very understanding and patient with me. This is a win-win for me.

I love Dr. Jefferies and staff as a dental resource. I recommend them highly. HOWEVER, I am SO tired of them suggesting that I need some cosmetic procedure or other procedure that is NOT necessary...and why are all of them around $4000?

Dr. Jefferies entire staff is wonderful. I had to have my first crown procedure and was so nervous. The hygienist and Dr. Jefferies were so calming, explaining every step of the procedure. I experienced no pain or discomfort. Dr. Jefferies is the most gentle dentist I've experienced in my 50 plus years. I do not hesitate in recommending his services.
