Agnes Matanga is the operational heartbeat of Prize Giving Day at Thornhill High School. As a Physics teacher with a Bachelor of Science (Honours) in Science Education, she brings to the committee the same precision she demands in the lab — clarity of process, rigour of outcome, and no tolerance for approximation where exactness is possible.

As Chairperson of the Speech and Prize Giving Committee, Mrs Matanga is the interface between aspiration and execution. She coordinates donors, manages the prize register, liaises with the school administration, and ensures that every student who earns recognition receives it with the dignity it deserves. No small thing in a school of hundreds.

Beyond the classroom and the committee, she coaches both netball and athletics — a woman who instinctively understands that excellence is built through repetition, discipline, and someone who refuses to lower the bar. SUMMIT is lucky to have her at its centre.

Rue Butete believes that the blank page is not a threat — it is an invitation. As an author whose work is dedicated to children's creative development, she designs interactive journals and learning tools built for curious minds and untamed imaginations. Her conviction is simple: childhood is meant to be spent discovering the world, not passively consuming it.

At SUMMIT, Rue is the guardian of the language. She curates the Tsumo proverb archive that powers the games, shapes the competition categories, reviews story submissions, and holds the creative standard for everything the platform produces. When a student enters the Story Weaver category and needs help with structure, layout, or narrative voice — Rue is who they call.

She is also the bridge between SUMMIT's cultural mission and its practical output — making sure that celebrating Shona and Ndebele never becomes an exercise in nostalgia, but remains a living, relevant, competitive discipline that young Zimbabweans are proud to claim.

Themba Bhebhe sat where Thornhill's students sit today. He walked these grounds. He carried this motto. Then he took it to the world. Over 24 years at the African Development Bank Group, he has shaped the economic trajectories of nations — serving as Country Manager for Uganda and South Sudan, Advisor to the Executive Director across Angola, Botswana, Mozambique, Namibia, and Zimbabwe, and as Chief Operations Officer for the Bank's Operations and Quality Assurance Committees.

Before the AfDB, Mr Bhebhe spent a decade in Zimbabwe's Ministry of Finance, rising to Chief Economist and Advisor to the Minister. He holds a Bachelor of Science in Economics from the University of Zimbabwe and a Master's in Development Economics from Williams College, USA.

He returns to THS not as a dignitary making a visit, but as a committed strategic resource for the school's revitalisation. His understanding of institutional investment, sovereign finance, and continental development brings a calibre of strategic thinking to the SUMMIT committee that most fundraising bodies never come close to. The students watching him on Prize Day are watching what Thornhill can produce.

Sacha Robinson's work is best understood as a collective effort powered by strong teams, community partners, and a clear commitment to building the kinds of systems people should already have. His role is often to architect the foundations — the infrastructure that enables others to build, participate, and thrive.

As CEO of Digni-Go Ltd and founder of ZyraBlok Labs, Sacha has helped lead the creation of platforms across the UK and Africa, each shaped by collaboration and local insight: Heyy-U (a sovereign handle registry supporting the world's 2.9 billion people without smartphones), MaiyoBot (WhatsApp-native commerce used by 300,000+ Zimbabweans), Quattro Careers (global talent infrastructure), One-Zim (community cooperative finance), and ZIVA Global CIC (mutual bereavement support for 2,000+ UK Zimbabweans). None of these systems were built alone; each reflects multidisciplinary teamwork and community ownership.

His MBA from the University of Bournemouth and CMI Level 7 Diploma in Strategic Management support a career spanning B2B corporate sales (AXA PPP, Equanet IT), retail leadership (Limpopo Foods), and innovation consulting. At SUMMIT, Sacha contributed to designing and delivering the digital fundraising engine — including the language-games platform, sponsor and donation store, website donation packages, and campaign architecture — achieved by working closely with stakeholders, volunteers, and partners under constraints that demanded shared problem-solving and rapid iteration.

For this committee, Sacha's value lies in the intersection of African diaspora economics, rapid platform deployment, and community-owned financial models. SUMMIT reflects the same principles he applies across all projects: systems that are sovereign, self-sustaining, and built to empower communities long after the original team has stepped back.

Paul Zimbizi is the kind of person every committee needs and rarely finds: someone who has done the real work, who understands how organisations actually function from the inside, and who comes back to serve his school not out of obligation, but out of genuine care for what Thornhill produces.

A Cranwell House boarder from 1982 to 1987, Paul left THS and went directly into industry, joining the Grain Marketing Board on a competitive Management Trainee Programme — the kind of selective entry that signalled institutional confidence in the people it chose. He rose steadily through the GMB, holding a series of operational and strategic positions before reaching the level of Regional Manager for Mashonaland West Province, overseeing one of Zimbabwe's most agriculturally significant regions.

His formal expertise is anchored in Post-Harvest Management, gained through a degree from TAFE Australia, alongside Associate Membership of the Australian Grain Institute — qualifications that placed him at the intersection of food systems, supply chain management, and agricultural economics at a time when Zimbabwe's grain infrastructure was central to national food security.

Today, Paul runs a civils, earthworks, and plant hire operation out of Chinhoyi, while also farming — two disciplines that reward exactly the qualities the GMB trained him in: precision, patience, and the ability to manage complex logistics under pressure. For SUMMIT, he is the in-country anchor: the person on the ground who knows the landscape, holds the relationships, and gets things done.

Tawanda Nixon Mangisi occupies a rare intersection: he is simultaneously a senior agricultural executive, an ordained pastor, and a leadership coach — three roles that, in his hands, are not compartments but a single coherent calling. Each discipline sharpens the others, and the communities he serves feel the difference.

His agricultural credentials are substantial. As former Head of Marketing at Syngenta Zimbabwe, one of the world's leading agroscience companies, Tawanda operated at the commercial and scientific frontier of Zimbabwean farming. He simultaneously served as Executive Committee Chairman of CropLife Zimbabwe — the industry body responsible for the responsible use, regulation, and advocacy of crop protection products across the country. In that role, he led initiatives directly targeting the proliferation of illegal agrochemicals, a crisis that undermines food security, farmer livelihoods, and soil health across southern Africa. His advocacy for climate-smart farming practices places him at the centre of one of the continent's most urgent conversations.

As a pastor, speaker, and mentor, Tawanda brings to every room something that most executives cannot: the ability to move people. His faith-based and motivational leadership has shaped individuals and communities across Zimbabwe, and his presence on the SUMMIT committee is not merely advisory — it is relational. He holds networks, builds trust, and opens doors that credentials alone cannot.

For SUMMIT, Pastor Mangisi is the community outreach engine: the person who ensures that what this committee builds actually reaches the people it is designed to serve, and that those people feel part of something, not just recipients of it.
