Dr. Najmuddin is an excellent doctor and shows genuine concern for all aspects of his patient's care and well-being. He spends the time getting to know you and your health concerns and answers questions in plain English and makes sure you understand.

Dr Najmuddin is an excellent clinician. Very knowledgeable with good “bedside” manners. He listens to me without my feeling rushed and truly wants to improve my pulmonary health
