I began seeing Dr. Marks-Cogan in December for my cat allergies. I was very worried that my allergies had gotten so bad that I would have to give up my two cats (my GP recommended that I do this). During my first visit, Dr. Marks-Cogan spent over a half hour getting to know me and explaining to me why I had only recently developed this allergy and what my options were. I've never had a doctor give me this kind of attention! I'm now taking allergy shots and already I've seen improvement when I'm at home with my cats. I would recommend that anyone with a pet allergy go see Doctor Marks-Cogan!
