Dr Kellar was really clear in his explanations and took time to address my concerns. The staff was nice and I did not wait long either. I felt very comfortable and confident in my decision to go here.

I have always liked and been satisfied with Dr. Kellar. I come from farther away since he is no longer in N. Barrington. I am not sure that I will keep coming to Northwest Pulmonary and Sleep since Dr. Kellar is only seeing newer patients. The nurse practitioner is in and out of the patient room too fast.
