I did all the blood tests and wanted to know the results about blood sugar and cholesterol and other I forgot to ask and he didn't do his job to share them with me and on my way out I realized and returned to the nurse and while I was waiting for him he told her falsely that he already shared the information with me, I really wasn't appreciated since I went through all the trouble for the blood tests and then seeing him for nothing, I reported it and I was told someone would be calling me and discussing the results with me but I never received any calls
