There are actually two Dr. Marshall Michaeliean's, father and son. They also have two offices, San Mateo and Daly City, but they each seem to work in both offices at times. I saw the younger one in the Daly City office for a consultation and San Mateo office for a root canal. He was very thorough in his explanation of what he was going to do and a very friendly guy. The staff was very professional and curtious, I felt very welcome there. They also were very careful to let me know my exact copay amount for the procedure before I came in - this was nice to know they wanted me to be comfortable with the $ before having the root canal. Highly recommened!
