I was at Northern Westchester Hospital in September 2012 for a full knee replacement. Dr. Evan Karas is my favorite doctor ! He has so much compassion, great surgical skills, professionalism !! He walked me through it all and it's appreciated.. being major surgery. My knee was in very bad shape and I needed extensive surgery. Dr. Karas has received numerous HUGS for being so wonderful ! The nursing staff.. excellent care.. My favorite hospital is definitely Northern Westchester Hospital. I trust in their wonderful care.
