About Diana Trejos Advise & Consulting

A perspective built between people, cultures, and contexts.

Psychologist · Consultant · Advisor · Strategist

My roots

Costa Rica is my starting point.

I was born in San José and grew up in Los Ángeles de San Rafael de Heredia, surrounded by nature, family, and community. Those roots shaped how I understand and relate to people.

My Career

A view that gradually broadened.

My path began with Psychology and expanded into International Development and Latin American Studies, three perspectives that allow me to understand people and regions from their history, culture, and social context.

WHAT DO I DO TODAY?

Between Europe and Latin America

I currently live in the Netherlands with my husband and our dog, Milly, while maintaining a close connection to Costa Rica and Latin America. My life and work, in many ways, unfold between these two regions.

From the Netherlands I work in two areas that connect the well-being of people with the development of organizations and communities.


Individual Counseling: I support people in managing emotions, anxiety, stress, fears, and frustration, especially during difficult times such as unemployment, separation, bad news, fear of driving, or frustration after failing an exam.


Consulting and advising: I collaborate with socio-environmental organizations and projects, mainly in Europe and Latin America, strengthening strategies, projects, alliances, research and resource mobilization to generate greater impact.

Often, my work begins with something seemingly simple but profoundly valuable: listening to an idea born from a person, community, or organization and accompanying them to turn it into a clearer, more solid, and possible process.


I deeply believe in working with communities, not for them. That same conviction guides my work in psychological counseling: accompanying the person, walking alongside them, and building the process together, without making decisions or doing it for them.


Living and working between both regions has enriched my perspective and allowed me to understand, also from personal experience, what it means to adapt to new contexts without losing our roots and ties to the place we come from.


CAREER PATH & WORK EXPERIENCE

An experience that connects strategy and people.

and impact

Over two decades I have built my career working with multilateral and bilateral organizations, governments, companies, foundations, social organizations and communities in different countries and contexts.

I have had the privilege of collaborating with the International Labour Organization (ILO), Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ), Organization of American States (OAS), Habitat for Humanity, European Association of Zoos and Aquaria (EAZA), Fundación Eterna, Fundación Rahab, Fundación Ser y Crecer, FENTRAGH and the SOLAC Institute, among other organizations.

My experience encompasses the direction and management of programs and projects, research and analysis, strategy development, building multi-sectoral alliances, resource mobilization, financing, fund and budget management, and organizational strengthening.

Much of my work has taken place where diverse people, organizations, sectors, and interests converge. I learned to understand complex contexts, build common ground, and translate objectives into concrete actions.

Today I combine strategic vision and execution skills: I can look at the big picture without losing sight of the people, relationships, and decisions that make it possible to put a strategy into practice.


I am pleased to recommend Diana Trejos, with whom I had the pleasure of working at Habitat for Humanity. She is a truly committed professional, passionate about helping others, and her dedication made a significant difference. She has a great ability to keep processes organized and ensure everything runs efficiently. She is also an excellent team player, always willing to collaborate and support her colleagues. Her positive attitude and approachable nature made working with her a very pleasant experience.

Diana is deeply involved in her work, and her enthusiasm is contagious. I am convinced that she will be a great asset to any organization or team she works with in the future.

I highly recommend Diana Trejos for her personal and professional qualities, as well as her commitment, leadership, and results-oriented approach. Throughout our collaboration, she demonstrated a strong ability to coordinate processes, engage institutional stakeholders, and analyze complex information, transforming it into clear inputs for decision-making.

I especially highlight his responsibility, ability to synthesize information, and commitment to excellence in every project he develops.

MY APPROACH

My way of working

Listen. Understand. Accompany. Co-create. Transform.

Every person, organization, and challenge has its own context. That's why I first listen, observe, and understand.


From there, I integrate analysis, experience, and sensitivity to build strategic, viable, and humane paths.


I believe in kindness, respect, and dialogue as essential parts of any process of change. Because peace is also built in everyday life: in how we listen, collaborate, and treat others.


Seeking to understand a social reality from the perspective of those who live it requires a different kind of listening, a sensitivity that doesn't always fit into theories learned at university or forms designed from a desk.


My work has been precisely at that bridge: translating my clients' needs, knowledge, and aspirations into institutional language, without losing their essence along the way. Adapting, structuring, and giving technical form to ideas without replacing the voice of those who best understand their reality.


Therein lies, for me, one of the most important differences in my way of working: not starting from what we believe a community or a person should need, but from first understanding what they really need, value, and want to build.


Today, my work brings together two dimensions that for me are connected: accompanying people in their processes of change and well-being, and advising organizations that seek to strengthen themselves, evolve and expand their impact.


This entire journey continues to remind me of something essential: we cannot fully understand a person without also understanding their history and context. And we cannot understand an organization without looking at the people who comprise it.
