Dr Fouzia Siddique
Consultant Clinical Psychologist
B.Sc., M.Sc., DClinPsy, MBA
Co-Founder & Co-Director – the Collective
I arrived in Dubai when I was little more than 6 months old and spent the formative decades of my life in the city. The multicultural melting pot of Dubai shaped my views on the central place of the community, our people, in elevating all of us so no one is left behind, and I have carried this learning with me in all my pursuits. Decades later, this journey would come full circle, when a visit to EXPO 2020, Dubai, and its theme of ‘Sustainable Development Goals’ (UN, 2015) would become the seed that grew into the idea behind ‘the Collective’.
Our guiding principle at the Collective – Ubuntu – “I am because we are” encapsulates our interconnectedness, shared humanity and compassion for all that exists in the universe. This belief is at the heart of my desire for pioneering a new collective model of psychologically caring spaces for the people who form our communities, the bedrock of civilization.
I come with a passion and motivation to build something for all of us and give back to our communities, cities and countries that have offered each of us the foundations for our futures. I have spent my professional life advocating for systemic, community centred and community led, psychologically caring spaces for all – our children, youth and older people, to invest in developing the leaders of tomorrow who can move forward with compassion as we progress to greater heights.
Leadership and development opportunities for our youth, psychological care for our children in schools, and learning from the wisdom of our older people while creating a compassionate community for them – this vision for support across the lifespan, as part of public health policy, and delivered through harnessing the power of the community, is the biggest resource we can draw on for creating the leaders of tomorrow. By setting up the Collective, David and I hope to play a part in contributing to this future for all of us.
While my interests are varied, ranging from history to astrophysics, and photography to attempts at mastering the piano (and failing spectacularly so far!) my professional journey has centred around my passion for healthcare, particularly, mental health, and by extension, its presence and impact on all aspects of life, especially at work – where we spend a major part of our lives, if not the majority of it.
My specific interest in workforce development and transformation manifested early, while observing my father’s business grow in Dubai. My first lessons in the optimisation, development, management, investment and transformation of the workforce came from him but my primary interest and passion for healthcare and mental health led me to Clinical Psychology. This path took me from Dubai, U.A.E., where I was raised and completed my undergraduate degree, to Bangalore, India, where I am a citizen of and earned my postgraduate degree, to ultimately, London, UK, where my passion for learning culminated in a doctorate in Clinical Psychology. Practicing in the NHS in the UK revived my interest in workforce development and business management, which was strengthened by an MBA.
Across my career, I have combined clinical expertise, strategic leadership, and workforce transformation to design, implement, and sustain complex organisational change. I have explored how health services evolve across diverse countries and cultures, and how workforces can be developed and remodelled in varying settings, particularly in the context of leadership, operations, strategy, and management. Throughout my career, I have engaged deeply with public health policy, population health, healthcare business models, service delivery in national settings, workforce planning, development and management, and the impact of national healthcare policy on the development of service provision, staff engagement and wellbeing, and in the implementation of health and workforce service models. My approach is grounded in systemic principles, ensuring that project deliverables are implemented sustainably while aligned with medium to long-term strategic directions and outcomes.
I bring an integrated, systems-level approach to workforce, leadership, and service transformation, informed by this extensive experience across national and international healthcare systems. My work supports organisations to design and implement strategies that strengthen workforce capability, leadership effectiveness, organisational culture and organisational resilience, and service sustainability in complex and evolving contexts.
My experience spans workforce strategy, optimisation, and transformation, supporting organisations to address recruitment and retention challenges, redesign roles and career pathways, and maximise the use of existing skills across clinical, non-clinical, managerial, and hybrid roles. This includes developing structured recruitment models, professional development frameworks, and progression pathways aligned to organisational priorities and population needs.
I work with leaders at all levels to build inclusive, compassionate, and effective leadership capability, designing and delivering bespoke leadership development programmes co-produced with staff and grounded in organisational realities. This includes strengthening supervision, enabling meaningful staff voice in decision-making, and embedding leadership practices that support performance, accountability, and psychological safety.
A core area of my work has focused on organisational culture, staff wellbeing, and restorative systems. I have pioneered, developed and led on quality improvement projects addressing bullying, harassment, conflict, and blame cultures through early intervention pathways, policy redesign, restorative practices, and capability-building initiatives. This is complemented by work on improving staff and patient environments, feedback mechanisms including staff conflict resolution spaces, and governance structures that support transparency, trust, and engagement.
I have also supported teams to embed trauma-informed and psychologically responsive approaches within services and leadership systems, drawing on experience of developing and implementing clinical and operational models at local, regional, and system levels. This work recognises the impact of adversity and trauma on both staff and service users and integrates these insights into service design, leadership practice, and workforce development.
My experience includes international and cross-cultural health system work, providing strategic insight into mental healthcare modelling, workforce planning, and service delivery across diverse contexts, including the Middle East. This global perspective is informed by the United Nations Sustainable Development Goals, particularly in relation to equity, wellbeing, sustainability, and the future of healthcare systems.
My professional journey has been guided by a recognition of the complex interplay between workforce optimisation, leadership, organisational culture, and service delivery. I have navigated challenging organisational environments, including punitive and exclusionary cultures, which have deepened my commitment to this work. I understand that workforce and cultural challenges carry profound psychological, financial, and systemic costs, requiring strategic, systemic, and sustainable solutions.
With the creation of ‘the Collective’, David and I hope to support organisations and partners such as yourselves, to move beyond fragmented initiatives towards integrated, systemic, sustainable solutions that improve workforce wellbeing, organisational performance, and human-centred outcomes for the communities we serve. We will partner with you to develop bespoke strategies that are grounded in evidence, informed by lived experience, and designed for lasting impact. Together, we will put some of my knowledge and experience into practice to contribute to developing your policies and organisation(s) in the way you hope for while contributing to innovating the best workplace environments and culture, globally.

David Van de Velde
Registered Mental Health Nurse & CIPD accredited HR Practitioner
Co-Founder & Co–Director – the Collective
Born into an intercultural and interracial household, I learned early on how to navigate the many layers of identity we carry—both within and outside our communities. My formative years, split between Belgium and Nigeria, shaped my worldview, which expanded further when I moved to the UK in 2008 to pursue my studies.
Over the next decade, I built a career as a healthcare professional, where I discovered a deep passion for workforce development and human resourcing—or, as I prefer to frame it, our community capital. While still in a nursing leadership role, I became increasingly interested in how organisations engage with their people through the systems and processes they design.
This curiosity led me to NHS England, where I supported the development of training, education, and workforce strategy across multiple regions of the country. To further strengthen my expertise, I earned Chartered Fellowship status with the CIPD (Chartered Institute of Personnel and Development), deepening my understanding of people practices in complex organisations.
Today, as co-founder of the Collective I seek to help clients create more holistic and sustainable approaches to healthcare consulting and healthcare service development based on the belief ‘I am because we are’.
My professional career and leadership journey are rooted in one core belief: when we invest in people as our human capital, services become safer, kinder, and more sustainable. This is informed by my upbringing and how I see the world: through a lens of belonging, respect, community, responsibility, and the practical realities and value of different perspectives. Culture is not an abstract concept, it’s something people live, every day, through the systems around them and the relationships within those systems.
In 2008, when I moved to the UK to pursue my studies, I started where the work is most human and most complex: in mental health. Working in a care-giving capacity gave me a deep respect for the everyday skill it takes to show up for people, patients, families, and colleagues, especially when resources are tight and the stakes are high. It also gave me a clear view of how organisational decisions land on real lives. I saw brilliant professionals doing extraordinary work, and I also saw how often they were asked to do it despite the system rather than supported by it.
That tension became a turning point for me. While still working in nursing leadership, I became increasingly interested in how organisations engage with their people through the systems and processes they design: how workforce plans are shaped, how training pathways are built, how roles are created (or left unfilled), how inclusion is embedded (or overlooked), and how culture is expressed through day-to-day ways of working. I saw firsthand who benefited and who was left out. I realised that many of the challenges we experience in organisational settings, particularly in healthcare, like burnout, retention issues, fragmented pathways, uneven staff experience, are not problems of motivation or effort. They are often problems of framework, processes and systems that govern the workplace.
That insight led me to workforce development and human resourcing, though I’ve always preferred to frame it as people capital and community – a collective of individuals. For me, this is not simply “HR” or “resourcing.” Many of us spend most of our lives contributing, working or participating in the creation and maintenance of such environments, be it either directly or indirectly. Therefore, the capability, confidence, wellbeing, and belonging of the people who make this possible is essential for any business that is serious about long term productivity and developing a culture of health and well-being. When human capital is valued, organisations become more resilient. When it is depleted, everything becomes harder: quality, productivity, innovation, creativity, safety, access, experience, and outcomes.
My curiosity about systems and design eventually brought me to NHS England, where I supported the development of training, education, and workforce strategy across large parts of the United Kingdom. This work strengthened my ability to operate across complexity: balancing national expectations with regional realities, aligning priorities across diverse stakeholders, and translating strategy into delivery that makes a difference on the ground. It also deepened my belief that workforce challenges are rarely solved by single interventions. Sustainable change requires coherent operating models, inclusive culture, credible governance, and practical mechanisms for improvement, not just good intentions and statements of intent.
To strengthen and formalise my expertise, in 2024 I earned Chartered Fellowship status with the CIPD (Chartered Institute of Personnel and Development). That journey deepened my understanding of people practices in complex organisations and sharpened my ability to connect the “people” agenda with organisational performance, quality improvement, and sustainable change. It also reinforced something I had learned through experience: good people practice is not separate from service delivery. It is one of the most powerful levers we have to improve it.
Over time, I have become known for sitting at the intersection of strategy and delivery. I bring structure to complexity, build trusted relationships quickly, and focus on outcomes that can be felt by staff and service users. My work has spanned workforce supply and development, education and training, assurance and improvement, and cross-system collaboration, often in environments where the pressure is high, the stakeholder landscape is wide, and the margin for error is small. Following my years of work on inclusive practices and creating safer spaces in the workplace in response to critical incidents, I now act as a panel member and investigation lead for ongoing internal employee investigation cases. This work has given me a deeper understanding of daily application of HR policies, UK employment law, organisation blind spots, and the importance of timely organisational learning. I am often struck by the extent to which empathy can guide and support the investigation process; to carefully adjudicate whilst also creating spaces for repair; how micro-cultures within teams create huge differences in experiences; how good intentions still lead to wrong decisions and cause harm; how often investigations take significant resources of time, labour and money; and ultimately how this impacts on both the complainant and the accused.
What guides my approach is a combination of lived experience, professional training, and an unwavering commitment to care. I understand the operational reality of healthcare and the emotional labour involved. I understand the strategic and business levers of planning, commissioning, training pipelines, staffing costs, governance, assurance, and culture change. And I understand that people experience isn’t a “soft” issue; it is a performance issue, a safety issue, and a moral issue.
I’m also deeply motivated by the idea that better systems are possible; systems that don’t rely on heroics, where inclusion is built-in rather than bolted on, and where staff feel valued in ways that are tangible, not symbolic. In my experience, the best outcomes come when leaders can see the whole picture: the data, the processes, the culture, the lived experiences, and the practical constraints—and then take considered steps towards something that feels more like the collective community we all would want to work in and for; around a shared, workable path forward.
Today, as co-founder of the Collective, and a global advisor, I bring this intercultural perspective, systems thinking, and strategic insight to support organisations in creating high-performing, inclusive, and resilient workplaces. At ‘the Collective’, we work with clients to co-design interventions that optimise workforce structures, build leadership capability, embed positive culture, and create psychologically responsive systems, all while ensuring tangible, sustainable outcomes. We help clients create more holistic and sustainable approaches to the development of their staff. My motivation for setting up this business is simple: I want to bring the depth of my experience across frontline care, leadership, workforce strategy, education and training, and people practice into partnership with organisations that are serious about building working environments that remain responsive to the needs of its members.
The philosophy that anchors my work is Ubuntu “I am because we are”. It is a belief in shared responsibility, shared outcomes, and shared humanity. In practice, that means I work with clients in a way that is collaborative and grounded: listening carefully, designing with the people closest to the work, focusing on what will actually land, and building capability so improvements can be sustained long after the project ends.
If you’re looking for a partner who understands healthcare from the inside, who can navigate complexity without losing the human story, and who brings both strategic rigour and cultural intelligence to the work; then I would like to welcome you and say – you are in the right place.

Our Collaborators

Our Collaborators are incredible people with a tremendous profile of work that we have had the privilege to meet and work with on our journeys to creating the Collective. They work with us across three different levels of this organisation. Some are founding members who joined up efforts with us early on at the beginning of this journey and continue to play a significant role in the direction we take. Others are partners who collaborate with us frequently on specialist projects pertaining to their areas of experience and specialisation. We also work less frequently with our associates when a project requires additional support or expertise.
In addition to our founding members, partners and associates, we are also counselled by a number of non-executive advisors who bring specialist expertise to work we undertake at the Collective. You will notice that some of our collaborators have multiple roles with us too.
You can find out more about our Collaborators and their journeys in the pages below.
