I'm having my invisalign done with Dr. Noor and it has been a very unpleasant experience. The office is very unprofessional. They did not disclose all the costs associated to the process. I was surpriced to found out that retainer is not part of the treatment and they will be charging additional money for future visits once I switch over to retainer. I hear complaints from other patients about unspecified charges billed to them as well. I don't feel that Dr. Noor explains my issues with invisalign clearly, often I find his explanations contradict themselves. I'm seriously considering finishing the process with another doctor if it doesn't cost too much more.
