I highly recommend TrainingCity for training services. I took a workshop for one week for training on VoIP technologies. After taking the course, I knew enough about the technology to set up my own VoIP system at home, and am qualified to get a VoIP job.

TrainingCity's course is organized, the topics are covered thoroughly and they have deep knowledge of the subject. In addition, my instructor was very personable and kept the class interested. I plan on taking future courses with TrainingCity.” Yvonne Young March 26, 2007
