I doubt that anyone would want to have negative reviews on their professional website. I sympathize with the frustration though because my first therapist (whose work style and ethic I had a lot of concerns about) also selects positive comments from people who don't even know him outside of the internet and puts them on his professional site. I wrote a mostly negative review on him on healthgrades.com and saw with interest that someone else also posted a very similar experience with him that I did not see anytime earlier even though I looked him up quite thoroughly.
