Keith Mazza's Wing Chun Levels 1-10 brings four decades of well-documented William Cheung lineage experience to a structured 10-level online curriculum, with unusually detailed wooden dummy drill breakdowns. The Somble platform is less polished than dedicated course sites, but the instructor credentials and depth of material are hard to match at this price point.
Wing Chun Levels 1-10 is the online video curriculum from Master Keith Mazza, a William Cheung-lineage instructor with over 40 years of martial arts experience. Hosted on the Somble platform, it brings Master Mazza's in-person Traditional Wing Chun Academy curriculum to an online format, with modules that progress through forms, drills, and wooden dummy applications, and built-in progress tracking ("mark as complete") for each lesson.
Alongside Traditional Wing Chun, Master Mazza's teaching draws on Tai Chi Chuan, Hsing I (Xing Yi), Baguazhang, Kali, and Qigong — reflecting a teacher with a genuinely broad internal and external martial arts background, not just a single-system specialist.
Master Keith Mazza was hand-picked by Grandmaster William Cheung to train and serve as the North American Liaison for the World Wing Chun Kung Fu Association — one of a small number of closed-door students of Grandmaster Cheung. Beyond his own Traditional Wing Chun Academy in Cherry Hill, New Jersey, Master Mazza has designed self-defense and stress-management programs for military units (including U.S. Naval Special Warfare Command and the U.S. Marine Corps), law enforcement, schools, and medical facilities — a track record that's unusually well-documented compared to many online-only instructors.
Both trace back to William Cheung, but through different teachers and academies — Master Mazza trained directly under Grandmaster Cheung as a closed-door student and North American Liaison, giving this course a strong direct-lineage credential within the Cheung branch.
A wooden dummy is recommended to get the most from the dedicated dummy-drill modules, though the broader curriculum (forms, drills, combinations) doesn't strictly require one.
Yes — it's structured as a 10-level progression with module-based tracking, though the platform itself (Somble) is less consumer-polished than dedicated course sites like Kung Fu Kendra's.
If lineage pedigree and instructor track record matter to you, Keith Mazza's Wing Chun Levels 1-10 is one of the most credentialed options on this list — a genuine closed-door William Cheung student with decades of teaching experience, including work with military and law enforcement. The platform itself won't win awards for polish, but the instruction underneath it is the real thing.
