While I dislike the name of the website, and the sort of gimmicky nature of their marketing, this treatment modality is tested and is widely used in clinical practice, and he's available for online sessions, which is incredibly beneficial for people sometimes stranded at home by disease activity. I just attended the WA Co-occurring Disorders and Treatment conference this week, and was able to attend workshops on Addiction-Free Pain Management. What I most appreciated about this modality is its focus on finding alternatives and recognition that many people with addictions or pseudo-addictions to pain meds have under- or mis-treated underlying medical issues driving their pain. He also said (this might not be exact, my notes are sometimes hard to read), "don't take away someone's denial without giving them something to replace it with."
