I live in Newtown and think Dr. Isgut's practice is great. I read the other reviews which are not fair to the doctor. They are based on his office, and the fact that they are busy. All offices are like this these days! They have taken me on a last second basis, taken time with us once we're in his office, and I think the staff is friendly and nice.
I would highly recommend Dr. Isgut and his staff. They are good old-fashioned medicine!
