About the Author

OSNEL SAINT JACQUES

Osnel Saint Jacques is a CPI (Candidate to the Engineering Profession), performance coach, and motivational author whose life took a dramatic turn after being diagnosed with Parkinson’s disease.
Instead of seeing it as the end of his ambitions, he chose to transform his pain into power — becoming a voice of strength, resilience, and purpose for people around the world.
With a background in electromechanical engineering and a degree in business administration, Osnel built his career in maintenance and reliability engineering, focusing on optimizing systems and improving performance. When Parkinson’s entered his life, he applied the same principles to himself — developing a mindset rooted in discipline, adaptability, and continuous improvement.
