I visited the Annapolis Rd location Glen Dale MD Saturday morning May 19 2018. My husband was having very bad tightness of the chest from Open Heart Surgery in March 2017. I asked at the receptionist desk how many people there were ahead of him. One of your personell told me that if his chest she told me why don't you take him to the ER then. We waited from 9.40 until 11.30 or after before he was registered. The lady at the desk got very smart with me.
