Continuation from previous..
I will be referring all friends, family and work associates to their practice. If you are needing a dermatologist and are in the DFW area, I highly recommend this practice, and Dr. Koon, specifically. Make a long drive if necessary. So happy I found them and you will as well!!!

Have visited Dr. Koone for a yearly skin health check for over 15 years. Those visits have always been very efficient and always starts with a "what can I do for you". He listens to my concerns and then does his own evaluation of things that I may not be looking for as I age.
