Dr. Harold "Jay" Jacobsen is a great endodontist and has some fantastic staff support. He completed a difficult root canal on my #2 molar (one of the 4 roots had 4mm of calcification) while causing no pain and only minor discomfort from the lidocaine shots. He's a very personable fellow and clearly dedicated to performing quality work for its own sake (in addition to the fees, I assume). Very positive experience.
