I had an excellent experience yesterday, my first visit, as an emergency patient. They took me in right away, late in the day, at least 5:30 pm. Doctor diagnosed me with a gum infection, which was causing me the most excruciating pain I’ve ever experienced. Gave me antibiotics, and today, after 3 doses, I have no more pain. Will recommend this practice to everyone I know. Thank you, Dr Bill!!
