“I’ve had such a great experience at Dr. Co’s practice at Bergen Medical Associates. The professionalism and patience of the team are impressive and appreciated. The time that Dr. Co spent with me to read over my medical history and ask questions to truly understand my symptoms was unlike any other Dr. I’ve seen. This has continued over several visits and tests prior to coming up with a solution and a plan.In today’s world of rushed medical care, I highly recommend you contact Dr. Co’s practice for a much better patient experience.”

“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!”
