I had a terrible experience with Dr. Kostiuk. I was having major problems with dizziness, which I later found out was caused by allergies. I was sent for a variety of ear tests and then I went to see Dr. Kostiuk to discuss the results. Because the tests showed there was nothing physically wrong with my ears, Dr. Kostiuk assumed that this was all in my head. He was actually fairly rude to me and not very compassionate at all. I tried to explain to him that I suspected that it may be caused by allergies, but he would barely listen. He suggested that I seek a psychologist. I actually started to think that maybe my problems really were in my head, but it was later confirmed, by another doctor, that my dizziness was caused by allergies, because they make my ears fill up with fluid. I will never go back to see Dr. Kostiuk ever again.
