Training on its own tends to fade once people get busy again. That’s why every programme we run includes coaching afterwards.
Before we design anything, we agree what you want people to do differently, and what that will change for the business. Then we build the programme around your real situations: your deals, your meetings, your people.
Practical, energetic sessions in groups of 12 to 15, where everyone practises on their own live work. Big enough for real energy, and small enough that nobody hides at the back.
Coaching workshops, 1-to-1 coaching and follow-up on real conversations, so the new habits hold under pressure.
Leaders speak up sooner. Managers coach their people and stop doing the team’s work. Salespeople lead with value and hold their price. When the way people think and communicate under pressure changes, the results follow.
“Shiera has an impressive approach for tailoring sessions to meet the specific needs of each leader, ensuring that the coaching experience is both relevant and transformative. Her approach combines insightful questioning with practical strategies, enabling one to identify their strengths and areas for growth.”
— MZ, Senior Director, Dublin Client, 2025
“My work is simple: help people think more clearly under pressure, and the way they speak, sell and lead changes with it.”
I’m Shiera, founder of Zenith Training and Development. My experience runs from IBM and international sales to coaching leaders and training teams across Ireland and around the world. I speak four languages and started out as an interpreter, so listening for what people mean, as well as what they say, sits at the heart of how I work. I was named a Top 10 Executive Coach in Dublin in 2020 and Top 15 in 2024.
