Every once in a while we are truly validated for the work that we do. This letter is one of those validations and I wanted to share. I am very proud of Nemasket and the work we do, and that is a reflection of the company that provides the daily management and support to allow us to do it well. Thank you. —Stacy Grass, Administrator, Nemasket Healthcare Center Dear Director: Under your guidance the Nemasket Healthcare Center is efficient, immaculately clean, homey and staffed by professionals. There are so many people to thank for the care, attention and kindness my Father received at the end of his life. For the six months of his residence, everyone was professional, patient, thoughtful, respectful and generous at every level of service. It is our hope you will convey this message to all your staff that they are indeed, a special group of people. Thank you for a job well done. The family of Manuel C.
