My primary was unavailable so Dr. Sieminski stepped up and not only agreed to see me same day, via Telehealth, but called me 3 hours earlier. He was able to diagnose and prescribe within minutes allowing me to quickly start the healing process. I’m very grateful for his professionalism and concern.
