I worked for a Dr.Johnson an endodontist with  an office in Frisco Tx  and a shared practice with fellow dentist. He dedicated himself to both practices. He was my first dentist to work under and he taught me so much, really he spent more time making sure I  was educated and confident in myself and what I was doing. It was a short time there but that by far was the best job and environment for me ever! I was proud of the work Dr.Johnson did and Equally proud of myself! It’s been since 2008-200@ but Even now I give thumbs up 👍 to dr. Johnson
