I took my friend to his primary care physician, another dermatologist, a vascular specialist, and then to Dr.Krathen, who was seeing him for a different condition. Dr. Krathen truly cared about my friend's health, researched the possible illnesses,.and after some simple tests, made an accurate diagnosis, and prescribed an effective treatment. I am eternally grateful that a condition other doctors let grow worse for months was cured within weeks of our visit to Dr. Krathen.
