I want to thank the people in the office as well as my regular delivery driver for supplies in the Newburgh, New York office. They have always been helpful for me and very courteous. My Dr sent a request for an ox2 concentrator and within a few days it was delivered. My driver is a great person always friendly and so helpful. The office staff has through the years have always responded well to my requests. Once again, I would like to thank them all for the service level they have provided me with. :)
