I can't say myself. A friend of mine though had some fairly accurate diagnosis for what the problem was (Always back to thyroid/adrenals) with him, although he already more or less knew this based on previous testing. Although he wasn't too happy to tell the truth in that he eventually was just back to a bunch of supplements again (Dr.Lam Approved) and only felt slightly better with very little change over 3 months with him. This to the surprise of Dr.Lam who expected a greater improvement, I can't say if this was just because my friend has a severe case but I somehow doubt it. It reminded me of my experiences in the past with Naturopaths.
I think for some people who have NO idea of whats going on and where to start it can be helpful, unfortunately it didn't appear to be the major cure my friend was hoping for. In fact shortly following his Dr.Lam consults he began doing Dr.Schulze protocols I was doing, to which he began seeing tremendous differences (Much more than anything else he had tried) that and beginning to take a bunch of adrenal benefiting herbs like Ashwagandha, Astragalus & Rhodiola.
This is just his experience, but for the price unfortunately I don't think he would recommend him much more than any other Naturopath to which he isn't a very big fan either.
