I know Dr. DeGregorio and consider her to be an exceptionally well-trained, experienced and caring and dedicated holistic dentist.  I've spoken to her at length and am very impressed with the depth of her knowledge and understanding about the critically important relationship of oral to overall health, and her ongoing effort to educate her patients.  She belongs to a number of highly regarded holistic dental organizations, including the International Academy of Oral Medicine and my Mercury Safe Dental Association. These organizations encourage taking a holistic, whole-body approach to dental treatment and promotes patient education.

Her commitment to healthy dentistry, her ongoing dedication to continuing education, and her concern for her patients health and well being, along with her commitment to safely remove amalgam fillings, makes her ideally suited to safely remove and replace mercury amalgam fillings. I wouldn't hesitate to have her as my dentist.
