These idiots that work there are the biggest idiotss you could ever meet. I have called there to get an appointment numberous times to get no answer. After getting in in touch with an old bat that seemed to be too old to even do the job it was like pulling teeth just to get a straight answer for what I needed and with an attitude too. After finding out what I needed to get done I sent my information in to get service... That was THREE YEARS AGO and still no call. I've been serviced by a real sleep center through Unverisity of Maryland which knows what they're doing. My cousin went there as well and her experience was terrible. Save your time and go to Harbor Hospital or University of Maryland in Downtown Baltimore.
