Dr. Kassir has read my post visit record from my ED visit and asked excellent questions about my illness after which she provided a detailed analysis of the situation, separating symptoms into follow-up visits with the appropriate specialists. As always, she was truly helpful. I recommend her to everyone I meet. You are lucky to have her on staff.
