Executive Coach. Facilitator. Founder of Coach You Ltd
and co-founder of Reimagining Change.
Trusted thinking partner to senior leaders navigating change, complexity,
and self-leadership.

I’m Marien Perez, and I help leaders lead more powerfully—not by doing more, but by accessing the clarity, presence, and resilience already within them.
For nearly two decades, I’ve worked with leaders at all levels, from entrepreneurs and emerging leaders to C-Suite executives and their teams, to shift how they see the world—and in doing so, how they lead. My approach helps clients tap into their innate capacity for insight, so they can meet complexity with grounded thinking, purposeful action, and human connection.
My clients often come to me when something is shifting—externally or internally. When everything feels urgent, it’s easy to lose perspective. I work with leaders to pause, reflect, and tap into the clarity and insight that spark real solutions—not just quick fixes.
My Approach
I combine a rigorous methodology with extensive practical experience—drawing from leadership psychology, neuroscience and an understanding of how our mind works.
Clients describe my style as warm, grounded, and direct. I bring both structure and inspiration, shaped as much by my academic background as by my Spanish roots.
I’m especially known for:
- Finding common ground – I help groups find shared meaning and deeper connection, especially when perspectives differ.
- Building collective momentum – I work with teams to align around purpose, creating motivation, trust, and inspired action.

Who I Work With
Most of my clients are senior leaders in transition—facing rapid change, expanding responsibilities, or deeper questions about how they lead. Common challenges include:
- Feeling overloaded or disconnected from purpose. Sometimes wondering “is this all there is?”
- Difficulty creating space to reflect, leading to reactivity and inefficiency
- Struggles with trusting and empowering their teams
- High-stakes decisions requiring clarity and composure
I also work with purpose-driven organisations ready to invest in their people’s inner capacity as a strategic advantage—from founders and board members to academic leaders.
