Can anyone name a hospital or doctor who is particularly skilled at prostate reduction laser surgery?

A friend is thinking about having Green Light Laser PVP. So long as it is inside the USA he can get there, but he is having trouble getting recommendations for this particular procedure. We’ve found a lot of information saying you need a great doctor performing it, but as to who they are google and other search engines aren’t saying.
If you can recommend a database or website with ratings or information about surgeons and urologists that would be helpful too.
