Patient Comments (1)
in Holyoke, MA |
Dr Kellogg is an excellent dentist. He is concerned about his patient's comfort as well as doing a superb job. He was the only dentist in the area at the time (13 years ago) when my husband had mercury toxicity, who used a dam and filter while removing the mercury filled fillings. So thankful he takes those precautions. Wish others would learn from him.
