The People Behind the Engineering

Behind every precision weld, every custom fabrication, and every integrated engineering solution stands a team of dedicated professionals who share one common purpose: building a cleaner, safer and more resilient Africa.

We are a team of Kenyan professionals united by a passion for industrial innovation. Founded in 1997, Plenser has grown from a small engineering workshop into one of East Africa’s most respected mechanical and engineering solutions companies. That journey has been driven by one constant: the skill, dedication, and integrity of our people.
