The group working at the 75th street location are one terrific bunch - very, very knowledgeable and extremely helpful in making sure that we, the clients, are well prepared to use the new equipment and that they are only a phone call away should we need any advice or adjustments - they literally go out of their way to make us feel cared for and well taught on how to use the new machines to get a proper and safe sleep. I would never hesitate to send any new clients to the staff at 75th st.
