Dr Osia always addressed my concerns, even when there were a lot of them. He is very friendly always and was my daughter's doctor too. I have nothing but positive things to say about Dr Osia. He is kind, knowledgeable and caring. He is what you want in a primary care doctor. If he is your doctor you will not be disappointed..??
