Calum Lewis
PGA Professional

Since qualifying as a PGA Professional in 2020, Callum combines his background in Sports and Exercise Sciences with a science-led, sequencing-based approach to the golf swing. His coaching focuses on improving how the body moves to create more power, consistency and long-term repeatability — with changes that deliver results from day one.

A short game and putting specialist, Callum brings unique insight shaped by both research and personal experience, including overcoming the putting yips early in his professional career. He has developed a comprehensive approach to putting analysis that helps golfers build confidence, consistency and control on the greens.

Callum’s philosophy is simple: every lesson should provide practical improvements you can take straight onto the course, while building a strong foundation for continued progress.
