Dr. Tate is the BEST in my opinion. I've had eight root canals and all of my molars are crowned. Dr. Tate did them all and I wouldn't think of letting another endodontist work on me. He's the best -- has never ever ever hurt me -- even with the root canals. The shot of novacaine is the most painful thing. The rest is a breeze -- and I've not had any problems afterwards either. I highly recommend Dr. Tate. The office staff is very personable, too. There's even two locations (that I know of. There may be more.) I know there's one office in east Cobb and one in south Cobb near Cumberland Mall.
