The school system referred us to this company to have my daughters hearing tested. We were told they were knowledgeable about children and testing the hearing in young children. However, they did not have a clue how to test my daughter's hearing. She is profoundly deaf, but can hear some. I was pretty sad that they school system referred us to this place to get her hearing tested. I think that if they say they have expertise in the area of children's audiology, they need to practice that.
