Case Study: 4As Leadership Training – A Game-Changer for Tombras, Ad Age Agency of the Year 2025

When Tombras, one of the largest independent agencies in the U.S., began scaling rapidly, it faced a common challenge: high-performing managers without formal leadership training. To meet the moment, the agency enrolled account leaders in the 4As Team Leadership Certification Program, equipping them with the tools to lead with clarity, confidence and impact. The result? A stronger, more connected leadership culture, better collaboration and ultimately, recognition as Ad Age’s 2025 Agency of the Year. Most importantly, Tombras embedded ongoing learning and peer support into daily workflows, making leadership development part of the agency’s DNA, leading to a ripple effect across teams.
