To me, one surgery and yet a relapse of chest pain was enough, I did not want another surgery. There had to be a better way, and sure enough I found Dr Lee. If I tell you how I feel after Dr Lee’s treatment, you won’t believe me; so I strongly urge you to go through his program.. you won’t regret it.

Mr. Ng

After 2 by-pass surgeries, 13 medications and so much weakness from side-effects; I almost gave up… until I listened to Thomas Adams & met Dr Lee. Now, after completing his program, I’m only on 4 medications, feel young & strong again, and play badminton 4 days a week.

Mr. Lau

I heard about the effectiveness of Dr Lee’s heart disease treatment program and I was confident that I could see an improvement in my constantly deteriorating condition if I just went through his program. I flew from Mauritius… and boy was the trip worth it. No more chest pain, side-effects of my medications reduced a lot, I feel more energetic, lost belly fat and I look younger!
