I used him to get my top surgery referral at the very end of 2014. He offers a $320 package. That includes 6 sessions and two copies of your referral letter mailed to you. It only took 3 sessions for him to get the content needed to generate my letter, so I had letter in hand roughly one month after starting therapy with him.
He's a good dude. Very nice, easy to talk to. The only downside is if you're located outside the UK, you may have to wake up extra early or stay up extra late to chat with him.
