Patient Reviews
Aug 14, 2024
Fantastic allergist. Does exactly what an allergist should so. Listens carefully and then does the diagnostic work. Tested me thoroughly in office right away. In 20 minutes, she found out I was allergic to something that I would never have expected. But we all change as we get older. Prescribed a simple low-cost nasal spray that does the job perfectly. Dr. Co says there are only a few months of the year when the spray is necessary. A great visit, a great result!
