His expertise lies in distal acupuncture techniques with immediate results. Sérgio has had the rare privilege of studying directly under the founder of the Balance Method, Dr. Richard Tan, and several first-generation disciples of Master Tung, including Palden Carson, Young Wei Chieh, and Chuan-Min Wang. Furthermore, he has deepened his knowledge through training with three disciples of Dr. Hu Wenzi, giving him access to the more hidden facets of the Tung lineage that are seldom discussed in general education programs.

What sets Sérgio apart as an educator is his ability to validate clinical results with empirical evidence. As a scientific researcher, he has contributed to peer-reviewed studies on nerve conduction. This background allows him to explain the electrophysiological effects of acupuncture in a way that is perfectly logical to both the skeptical patient and medical colleagues alike.

In addition to his busy clinical practice in Portugal, Sérgio shares his knowledge with hundreds of students worldwide. He is a passionate lecturer known for his ability to translate complex theories into practical, reproducible protocols. Through his popular YouTube channel, Acupuncture Insights with Sérgio Ferreira, and his appearances at conferences and on television, he remains dedicated to promoting high-quality, logical, and effective acupuncture.
