My experience was awful. He creates one problem after the other billing you more and more. He is a bully.

Dentist John Machell is an exceptionally gifted holistic dentist who produced some truly remarkable work. With attention to detail and very high standards, he spared no effort in creating for me a very innovative lower partial denture that enabled greater chewing ability and paired it with a lovely, comfortable upper denture. Being personable and caring, his staff helped to put me at ease. The harmony and cooperation between staff members created an atmosphere that was reassuring and calming.

I have been a patient of Dr. Machell for about six years now and I have had a lot of different work done. I am normally very nervous with doctors and dentists, but my experience with this office has been very positive. Everyone (especially Kathy and Malissa) has gone out of their way to put me at ease. I trust Dr Machell and like how he fully explains everything to me. I am pleased with the care he gives me and with the fact that he wants everything to be just right. I highly recommend him.
