Meet Col. Zahl Tantra (Retd.)
With over 35 years of experience spanning military service and corporate leadership, I’ve built my career solving complex operational challenges in demanding environments.
Military Foundation
 I served 31 years in the Indian Army Service Corps, where I led logistics operations, managed supply chains under pressure, and built high-performing teams. Military service taught me discipline, strategic thinking, and the importance of execution—lessons that inform every client engagement today.
Corporate Leadership
Founding Zentra Consulting (2025)
Zentra Consulting represents the natural evolution of my career-leveraging 35+ years of operational expertise to serve multiple organizations simultaneously. Rather than confining my experience to a single employer, I now deliver transformational results across diverse client engagements.
