I highly recommend Dr. Ray and his brother Dr. Rich. They are excellent endodontists. They are happy to take the time to share any information the patient wants to know to feel more at ease. They are very conscious of your pain level, and take as much time as is necessary to avoid sensing any pain.
I have had a couple of root canals done by them over the last few years, and have had no problems or pain since.
The only bad experience I had was with the son of one the brothers, who was condescending and in a hurry to get me out of the office on an emergency visit.
If what is important to you is experience and reliability (rather than a health spa atmosphere), definitely visit Dr. Munaretto.
