About us
The independent voice your clients will actually talk to.
When your clients speak to Thissen Consulting, they are not talking to a colleague, a project lead, or someone with a stake in the relationship. They are talking to an independent professional with no agenda, which is exactly why they speak frankly.
That independence is not incidental. It is the whole point.
Why independence is the only way to get the truth
Your project teams have strong relationships with clients. But those same relationships make genuinely candid feedback almost impossible to collect internally. Clients moderate what they say to protect the relationship, to avoid awkwardness, or simply because they don’t want to be the bearer of bad news.
An independent interviewer changes that dynamic entirely.
Because Daphne has no stake in the day-to-day working relationship, clients share what they actually think: concerns they have not raised, opportunities they have not mentioned, and assessments of your firm that never surface in project meetings or account reviews.
The result is not a score or a survey response. It is the kind of intelligence that changes how you manage your most important relationships.
How Thissen Consulting Works
Every engagement begins with a briefing to understand your objectives, your key relationships, and what you most need to know. From there, Daphne conducts structured, confidential one-to-one interviews with the clients and stakeholders you identify.
Confidentiality: Individual responses are never attributed without permission. Clients know their candour will not damage the relationship.
Consistency: You will always deal with Daphne directly, and so will your clients. No associates. No handoffs.
Discretion: Thissen Consulting operates under strict data protection principles and will never encounter a conflict of business interests.
Depth: Interviews are structured but conversational, designed to surface the insights that surveys and account reviews miss entirely.
Findings are consolidated into a detailed report and presented directly to your leadership team, with clear recommendations and a discussion about next steps.
“Daphne provides a thoughtful and highly professional client feedback service that brings real clarity and value to our design process. The insights are consistently well-structured, perceptive, and actionable, helping teams to better understand client priorities and improve outcomes. Working with Daphne is always straightforward and collaborative, and the quality of the feedback she delivers makes a genuine difference”. Nigel Ostime, Consultant, Hawkins\Brown.
Daphne Thissen
Founder and Director
Daphne Thissen founded Thissen Consulting in 2018, with a singular focus: helping professional services firms understand what their clients genuinely think of them.
Her background is directly relevant to the firms she works with. Educated as an architectural historian in the Netherlands, Daphne came to the UK to work for English Heritage, before moving into a senior roles at the Employment Policy Institute and the Embassy of the Kingdom of the Netherlands, where she was responsible for research, reporting, and advising on bilateral relations and cultural diplomacy.
It was this combination, deep familiarity with the built environment, and professional training in listening, reporting and navigating complex stakeholder relations, that shaped the approach Thissen Consulting brings to every client engagement.
Today, Daphne works exclusively with engineering and project management consultancies and architectural firms across England. She conducts every client interview personally, which means the quality of conversation, the depth of insight, and the discretion of the process are consistent from the first interview to the last.
