Hi — my name is Thierry and I believe that everyone should be able to flourish and make a positive impact in the world. I work with leaders and professionals to realise their personal vision of success, aligned with their purpose and values.

Whether you want to grow your career, lead more authentically, get clear on priorities, develop your business, be more intentional, or simply find out what’s next for you — my mission is to support you to get there.

Since founding True Horizon Coaching in 2020 I have worked with dozens of people around the world — emerging leaders, CEOs, graduates, mid-career professionals, freelancers and entrepreneurs — in sectors including Geospatial, Digital and beyond. So far, almost all of them have achieved their desired outcomes. You next?

Executive Coach

“When I feel stuck Thierry always gets me to think differently, and I end up walking away with completely new ideas.”

Executive coaching for leaders

Create some headspace to unpack your world and chart clear ways forward. Whether you want to lead with purpose, prioritise goals, untangle complex issues, get clear on strategy, grow as an authentic leader, build confidence, or simply check in with someone you can trust, I work with emerging and successful leaders to achieve more impact and fulfilment.

Career coaching & mentoring

Grow your career — or reimagine it entirely. Clarify your aspirations and leverage your strengths and passions to get there. I work primarily with mid-career professionals who want to reassess their priorities and aspirations, but have also supported a fair number of graduates. Note, rather than just give advice I will mostly help you find your own answers. This solution-focused approach is proven to be highly effective.

Entrepreneurs & freelancers

Running a business can be a lonely place, whether you’re leading a growing business or working on your own. Coaching provides perspective, support, constructive challenge, ideas, accountability, and more — enabling you to move forward with clarity, focus and confidence. Simply put, the people I work with value bouncing off with someone who is on their side.

Productivity and wellbeing

Work is an important part of our lives. As such it should enrich us, otherwise what’s the point? As a leader I always made wellbeing a priority — for my team and for myself. This led to transformation as a natural outcome, not a goal. As a coach, I can work with you to establish productive habits for positive outcomes.

Groups and teams

I provide coaching and training for groups and teams, as well as workshop facilitation for strategy, innovation, team building and more. Check out my teams page for further information. I will help your team reboot, get on top of things, and reimagine the journey forward in a way that is fun, inspiring, and brings everyone together.

How it works

Individual coaching sessions are private and confidential, held remotely via video call. In-person coaching, team coaching, and group facilitation available on request.

To understand more about coaching, check out the FAQ page. If you’re new to coaching, the only way to truly understand its benefits is to experience it. See what my clients have said about their coaching experience, or contact me to schedule a trial session.
