I came in for an appointment late December of 2020 to see what I could do for my acne. At first, everything was fine and I got checked in by the nurse. However, once Dr. Liang came in, I felt like as if he did not care about me at all. Dr. Liang came into the room super rushed and I saw him for less than 7 minutes.First, I began explaining my conditions for my acne and I was explaining how I wanted to possibly go on accutane. Then, Dr. Liang interrupted me and said how I can't go on accutane immediately, I have to get prescribed a medicine first and check back in a month. I was totally okay with that until then, Dr. Liang said he was prescribing me Clindamycin, Trentinoin, and doxycycline antibiotics. The problem with that, however, was that I had gone to Dr. Liang in 2016 and he had prescribed me the same exact group of medicines for my face. When he said he was prescribing me these medicines, I tried to stop him and let him know that I had previously gone on these medications before four years prior and they didn't have any effect. However, before I could even say that, Dr. Liang, word by word, said, "Be quiet and let me finish".As in, he wanted me to be quiet and let him finish describing the medicines he was prescribing me even though I was trying to tell him that there was no need to describe them because I've been on there before. I wanted to let him know that maybe we could use a different variant of medicines but after he told me to shut up, he literally left the room.Thus, not only did I see Dr. Liang for less than 10 minutes, but he prescribed me the same exact medicine from four years prior. I literally found the old prescriptions from 2016 and can include the photos as proof if anyone wants to see it.I was very disappointed and angry after my appointment. For a dermatologist, I was hoping he would actually listen to my problems rather than shut me out and disregard me in a span of seven minutes. If you are in the Southwest suburbs, please save your money and do not go to Dr. Liang if you don't want to get your time and money wasted.
