Who We Are
Resonance Leadership Advisory
The definitive framework for accelerating strategy, culture and leadership
We don’t sell theory or create external dependency.
We help you build what most people only teach – and, in the process, elevate strategy, leadership and culture in the flow of real work.
David is an engaging leadership facilitator and coach. I have definitely seen an improvement in my presence and have better understanding of how I can interact better with my team and other key stakeholders.
The content David delivers on cultural transformation and leadership development is real and relevant. As I step into a new Executive leadership role, David’s guidance has proved really valuable for me.

DAVID JOSHUA
David Joshua is the creator of The SCL Accelerator™ – a cohort-based programme that aligns strategy, culture and leadership while tackling executive level business challenges in the flow of work. He is the founder and lead advisor of Resonance Global Advisory, a boutique advisory that helps executive teams turn strategic intent into tangible behavioural change and measurable enterprise-level results.
Over a 20-year career, David has reported to international banking CEOs, led national sales teams to deliver 10x revenue growth, built award-winning investment propositions, and coached world champion athletes and multinational CEOs. Today he brings that commercial rigour into SCL programmes for mid-sized organisations seeking excellence in strategy, culture and leadership.
Since 2019, David has fused Google’s leadership blueprint (learned directly from their Chief Learning Officer) with a business school approach to strategy and leadership (his flagship programme at Henley Business School consistently earns a 9.7/10 NPS score).
Through The SCL Accelerator™, David has helped organisations such as Discovery (the innovative financial services group behind Vitality) and Wellhub (a global $bn tech company) strengthen their leadership bench, build cultures of clarity and candour, and deliver strategic projects that stakeholders buy into and benefit from.
David is a Penguin-published investment author, holds top-tier qualifications across banking and investments, and is an MBA candidate with Henley Business School. Beyond the boardroom, you’ll find David in the mountains, searching for a wider perspective and a deeper presence.
“Transformation doesn't begin to capture what David facilitates… working with David is the best investment you can make.”
~ Tim Fish, Founder and Group CEO, Multimedia.
