I did a free consult with Dr. Lam and I have read his book. I believe he is an extremely knowledgeable doctor but I did not like his "attitude" and business style. He seemed to be eating food (noodles?) while consulting with me and he was very blunt and curt. I tried to figure out how much he charged - there are not set prices, they try and get you for as much as you can but they call it a "sliding scale." I bought his book and it is EXCELLENT. If I had a lot of money I'd have worked with him but I have lost my business and income due to AF and am now living with parents. Good luck!
