Top-rated dialysis centers in Connecticut
Centers with the same star rating are listed alphabetically — CMS does not rank within a star level. 3 Connecticut centers have no current rating (often newer or low-volume facilities) and are excluded here but listed on city pages.
How to use this list: shortlist 2–3 highly rated centers near you, then call to confirm chair availability, shift
times, and insurance. Star ratings summarize past measured outcomes — they're a strong signal, not a guarantee.
