Christian graduated in physiotherapy from Université Laval in 1989 and completed his training in orthopaedic manual therapy in 1999, earning the FCAMPT designation (Fellow of the Canadian Academy of Manipulative Physiotherapy). He has worked in private practice since 1989 and was co-owner of Apex Physio clinics from 1994 to 2021. He continues to practise within the Kinatex group, which acquired the clinics in 2021.

Involved in teaching at Université Laval since the beginning of his physiotherapy career, Christian was appointed practical training coordinator within the Faculty of Medicine in 2001. Since 1997, he has also passionately shared his expertise in advanced musculoskeletal physiotherapy through the OPPQ and AQPMA.

With a particular interest in spinal manipulation, he served on the OPPQ advisory committee in 2014–2015 to support the implementation of regulations governing manipulation in physiotherapy. He has since taught spinal manipulation through continuing education courses.

For several years, Christian has also drawn on his extensive experience to serve as an expert in professional liability cases. Known for his practical approach and enthusiasm for sharing knowledge, he has supported clinicians in developing their skills for several decades.
