Just looking around, and I noticed that not only is this site the first non-official google result for 'Benchmark Transitions,' but it engages in a DIRECT defense of the institution (particularly adressing recent court cases). They DO NOT link to any student testimonies (for obvious reasons), and their attempts to defend Benchmark indicate that they have certainly NEVER seen the fornits boards or talked to any students. Instead they say that Benchmark "deserves its reputation as one of the most if not the most trusted facility in its class for excellence of service, innovation, and self-assessment."

They don't seem to have any comment boards (of course) but there might be a way to deal with their prominence on google...
