I feel Dr Karn is a down to earth dr who takes his time to listen and a person who cares for his patients also. He does explain what is happening and what can be done, its also up to the patient to take of themselves too as he explains diff. Ways this can happen. He tells us what's going to happen next so we're ready. Very through doctor. Great manners, great personality, great dr!
