Dr. Nishan is an excellent doctor. He treats you as a valued person. He always discusses tests taken thoroughly. While my husband was at an appointment with Dr. Nishan, he was concerned with my cough and referred me to a pulmonologist. He saved my life. He is a truly caring person. We have recommended he several times. He is what all physicians should aspire to be. - Verified patient
