"Dr Mario Oliver of Graybill Medical is a terrible Dr who absolutely DOES NOT CARE about you as a human being at all!!! BEWARE & RUN AWAY go elsewhere if you want a real Dr to give you actual CARE!! He is a dr for the money only! Greed is why he goes to work each day. He wants to make the most money off of you in reach visit but he DOES NOT care at all about you or your illnesses or injuries!! He gives horrble care, he treats you like a new patient each time with no acknowledgement of past visits or that he even has a clue what is going on with you even with your medical history in from off him. He should not be practicing medicine on anyone. "

"My regular primary care physician, Dr. Matta, was out of town, so I saw Dr. Oliver instead via telemedicine. At the beginning of my appointment, he greeted me with the previous patient's name - this was not a big deal, but did not feel great! When Dr. Oliver asked why I had come in for an appointment, he didn't let me finish my explanation (I had a flare up of rashes) - he told me that he couldn't take my concerns at face value and could not see my skin clearly enough through the video camera on my computer, and nearly refused to help me. I asked for routine blood work since it had been several years since last had blood work, just to make sure that my flare up wasn't related to that. He initially said he could not just do lab work for no reason; however, after a long discussion, he later changed his mind and allowed me to get blood work. I also mentioned that my dermatologist had given me a steroid cream for the rash and it wasn't helping. Dr. Oliver kept referring to my rash as "acne", ...
and saying that my dermatologist doesn't know what she's doing by giving me a steroid cream for "acne". I had to explain multiple times that it's not acne - it's a rash. I don't normally write reviews, but I did not feel great walking away from this appointment. I didn't feel like Dr. Oliver listened to me or took me seriously. Additionally, I felt like he was condescending toward me and my dermatologist. I know this is a difficult time for everyone, but there is no excuse for that kind of patient treatment. I wish him well, but I hope Greybill sees this and talks to him about it! Positive note: Dr. Oliver's nurse was very kind and did an amazing job getting me set up for my telemedicine appointment! "
