About · The practice and the practitioner

I came to copy through design.

Most B2B copywriters can see words in isolation. I learned to see hierarchy, layout, conversion intent, and brand systems first, then learned to write the words that go inside them. That is why my copy does not float in space. It sits inside a structure I helped think through, on a page that is built to convert, in a voice my client's team can keep speaking after I am gone.

Practice
Why I do this

Most B2B copy is bad in a way that is fixable.

Companies pay agencies six figures for landing pages that bury the buyer's outcome under three layers of category vocabulary. The fix is not more talent. The fix is one person owning the argument from positioning to closing CTA, with enough background in design and brand systems to keep the layout honest while they write.

That is the work I find interesting. That is why I built this practice instead of joining an agency. I bring four disciplines to every engagement that most copywriters bring only one of, and the convergence is what produces work that ships and converts.

The non-linear path Four disciplines · One practice
01 Design
Hierarchy, spacing, the geometry of where the eye lands. I started here.
02 Branding
Voice systems, identity, what should and should not sound like the company.
03 Advertising
Direct response discipline. Hook, claim, evidence, ask. No wasted line.
04 Copywriting
Argument structure. Specificity. Position before persuasion.
How I work today

Senior B2B copy that ships and converts.

Most copywriters can see one of those four. I bring all four into every engagement, which is why the work I produce sits inside the structure of a page rather than in spite of it. The buyer reads the headline. The team can keep writing in the voice. The page actually converts.

Beliefs
What I believe

Four positions my whole practice runs on.

These show up across every service page, every engagement, every conversation with a client. They are not new ideas. They are the few that have survived 120+ engagements and that I would defend in any room.

Principle 01

Positioning is upstream of copy.

Most "copy problems" are positioning problems wearing a costume. I will not write your hero until your buyer is named, your category is defined, and your top 3 objections are surfaced. The page that fixes itself is the page that started with the right brief.

Principle 02

Specificity beats persuasion.

A real number in the headline ("18% forecast variance") defends against AI sameness and category vocabulary in a way no clever turn of phrase can. The senior move is to be more specific, not more clever. Specificity is the rarest thing in B2B copy and it is also the cheapest one to produce.

Principle 03

One vendor should own the seams.

Three-vendor briefing chains kill more pages than bad copy ever has. The copywriter writes for a layout they never saw. The designer builds for an argument they never quite understood. The developer ships what compiles. Collapse those seams to one owner and the page you ship is the page you intended.

Principle 04

Saying no is a seniority signal.

A senior practice is defined as much by what it says no to as by what it says yes to. I do not work with clients I cannot defend, on briefs I cannot solve, at terms that turn the work into a treadmill. The "do not work with" list is published openly on the FAQ page. It is a feature, not a defect.

Person
A personal note

The person behind the practice.

I read more nonfiction than is healthy. I was a working designer before I was a working copywriter, which is why I get cranky about layout when copy is treated as floating text on a page that nobody thought through. I think most B2B websites are uglier than they need to be, and that this matters more than most people pretend.

When I am not writing or thinking about how a page should be argued, I am usually walking somewhere in Lima trying to think about something that is not work. Some of the best headlines I have ever written have come on those walks. None of them have ever come from a brainstorming session.

The clients I work best with are the ones who treat copywriting as strategy with words attached, not the other way around. If that sounds like the engagement you want to have, send me a brief.

Ready to talk

Send me a brief. I will respond within two business days.

Tell me what you are trying to fix, ship, or launch. If I am the right person for the engagement, I will say so. If I am not, I will tell you that too, and where to look instead.
