A practice built around careful thinking and honest counsel.
Quillwood Advisers exists for organisations that want advisory engagement to feel more like a private study conversation than a consulting delivery.
Return to HomepageThe Quillwood Story
Quillwood Advisers was founded in Bangkok by practitioners who had spent years in larger advisory environments and noticed that the work they found most valuable — the slow, careful thinking alongside a leadership team — rarely fit comfortably into a standard engagement model.
The name draws on the image of writing as a considered act: measured, deliberate, and intended to be read again. That quality — of ideas worth returning to — shapes how we approach every engagement we take on.
We work from Bangkok and engage with businesses across Thailand. The practice is deliberately small. This is not a matter of capacity so much as preference: we take on work we can do well, at the pace it requires.
Our advisers have worked across industries including manufacturing, financial services, professional practices, and family-held trading companies. We bring that breadth of exposure to each engagement, alongside the discipline to focus on what is specifically relevant to the client in front of us.
What Guides Our Work
Thoughtful over fast
We do not push toward conclusions before the thinking is ready. Good advisory work takes the time it needs.
Honest over comfortable
We present what we find, even when it sits at an angle to what a client hoped to hear. The value of outside counsel depends on this.
Client-led, not agenda-led
We do not arrive with a preferred framework. We work to understand the situation as it actually is, then offer what is genuinely useful.
Discretion as a standard
The nature of the conversations we hold requires that confidentiality is taken seriously. It always is.
Those Who Do the Work
Each engagement is led by a senior adviser. We do not pass work to junior staff once an engagement has begun.
Jonathan Mercer
Senior Adviser, Strategy
Jonathan has advised leadership teams in Thailand and Southeast Asia for over fourteen years, with a particular focus on strategic positioning for family-owned businesses navigating generational change.
Patcharin Charoenwong
Senior Adviser, Family Enterprise
Patcharin works with family businesses on ownership structures, succession conversations, and the relational dimensions of shared leadership. She brings both cultural depth and analytical rigour to her work.
Richard Lau
Adviser, Written Analysis
Richard specialises in research and written work — gathering information, synthesising complex situations, and preparing clear documents for leadership consideration. He has a background in law and corporate governance.
How We Maintain Quality
The quality of advisory work is not measured by deliverable length or meeting frequency. It is measured by whether the thinking served the client well.
Senior-Led Engagements
Every engagement is led by an adviser with substantive experience. Initial conversations, working sessions, and written outputs all receive direct senior attention.
Scope Agreed in Advance
Before any engagement begins, the scope, timeline, and expected outputs are agreed in writing. There are no surprises in billing or deliverables.
Confidentiality Protocols
Client information is handled with care throughout every engagement and afterwards. Mutual confidentiality arrangements are available at the outset if preferred.
Reviewed Outputs
Written documents go through internal review before delivery. We check not only for accuracy but for clarity and appropriate tone.
No Undisclosed Interests
We do not receive referral fees or carry commercial arrangements that could influence our counsel. Independence is a foundation of what we offer.
Debrief on Completion
Each engagement concludes with a closing conversation reviewing what was covered, what was learned, and what the client chooses to carry forward.
Business Advisory in Bangkok — A Different Kind of Engagement
Quillwood Advisers works with companies at moments when good thinking matters: a strategic crossroads, a family ownership conversation that has been deferred too long, or a decision that deserves more careful analysis than internal resources allow. Our location in Bangkok's Bang Rak district places us within easy reach of the city's business community, and we travel within Thailand for engagements that call for it.
The advisory services we offer are defined by their pacing as much as their content. A strategic review that runs over eight weeks is not slower than one completed in a week — it is more thorough. The thinking that happens between sessions, in the days after a conversation, often produces more useful insight than the session itself. We build this into how engagements are structured.
For family businesses, the advisory relationship requires additional care. Family ownership brings strengths that purely institutional structures cannot replicate — long horizons, committed ownership, shared identity — but it also brings complexity that benefits from outside facilitation. Our approach to family business work begins with listening, individually, before any group session takes place.
Written briefings sit at the more focused end of our service range. They suit a leader who knows broadly what they need to understand but wants a clear document they can read, revisit, and share selectively. We gather information, form a view, and write it up with the care of a considered letter rather than a templated report.
Have a matter in mind?
An initial conversation carries no obligation. We are glad to discuss whether what you are facing is something we can usefully assist with.
