Wei Vern has always harboured an intense passion for movement and sports which led her to ultimately pursuing a degree in Physiotherapy with MAHSA University, under the programme of Anglia Ruskin, United Kingdom.

She has constantly engaged herself throughout her tertiary studies with various clinical placements to gain a diverse experience in her clinical practice. This further enhanced her interest in movements being integrated as a functional system.

Wei Vern then kick-started her STOTT PILATES^® training upon joining Pilatique Pilates & Physiotherapy studio in Malaysia in 2018. An ardent believer in active rehabilitation and holistic wellness, she has been helping clients achieve their goals to be pain free through incorporating STOTT&njbsp;PILATES into her treatment approach.

This fueled her further to complete her full certification in 2021 and eventually becoming a Merrithew^® Instructor Tra­iner specializing in Matwork & Reformer in 2022.

After graduating with a Masters Degree in Architecture, Wenqi decided to turn her passion for Yoga into her profession. Wenqi also has also qualified as a marathon National Level 2 Athlete. After being introduced to Pilates in 2016, she became interested in this training method and started learning STOTT PILATES^® in early 2017. She was deeply impressed by its logic and scientific nature and decided to become an Instructor Trainer of STOTT PILATES, to influence more people with this method. She has always maintained a strong interest in yoga, physical fitness training, rehabilitation, mind-body science, philosophy, art, and other aspects. She became a STOTT PILATES Instructor Trainer in September 2022 and now enjoys sharing mindful movement knowledge with her students.

Willie began her health and fitness career in 2009 as an evidence-based nutritionist and later expanded her practice by qualifying as a personal trainer. She now specializes in strength-training programs that enhance body composition, improve performance, and reduce injury risk.

Willie’s introduction to the STOTT PILATES^® method was a pivotal point in her professional development. The method’s biomechanical principles and emphasis on precision and purposeful movement deeply resonated with her, motivating her to pursue advanced qualifications and ultimately train as a STOTT PILATES Instructor Trainer.

In her current role, Willie is dedicated to promoting STOTT PILATES principles within the broader fitness and movement field. Through her teaching, she supports professionals and enthusiasts in developing intelligent, functional movement patterns that enhance strength, efficiency, and overall well-being, contributing positively to the evolving landscape of education in the movement sciences.
