Stop letting typos kill your credibility.
Start hitting "Send" with confidence.

One error in a high-stakes document can overshadow everything else on the page. Small errors signal small attention to detail: One glaring error in your document, and your reputation takes a hit.

[ PLACEHOLDER: emotional agitation ]
A tiny typo can erase a whole page of trust.

Are you wasting time proofreading your own documents
—and still seeing errors slip through?

You've re-read your work a dozen times. You're 90% sure it's clean. But after spending hours with your own words, you can't see your own typos, inconsistencies, or mistakes. Other solutions are futile:

  • Your coworker's "quick check" lacks context and a trained eye. They can't catch the mistakes that cost you credibility.
  • Spellcheck and ChatGPT lack human nuance—marking stylistic choices as errors while subtle, complex errors go undetected.
  • A cheap freelancer will "fix" your voice until it sounds sterile.

None of them catch the mistakes that can cost you your reputation.

Proofreading your own work doesn't make it better. It makes you worse.

Your documents deserve a trained expert,
not another software pass.

It's time to gain the confidence that comes from having a professional proofreader on your team.

I've watched even the most intelligent, educated business leaders make errors that disrupt, distract, and detract from their communication.

At the same time, I've found myself uniquely suited to eliminate those errors:

  • I have a talent for seeing mistakes that are invisible to others.
  • I've learned how to rapidly become a subject matter expert in new industries, so I can proofread like I've been there for years.
  • I deeply enjoy the work—proofreading is my personal flow state.
  • I've studied under writing instructors from Harvard, MIT, and Yale, giving me a keen, critical eye.

So I have dedicated my career to proofreading complex, high-stakes documents to ensure they have a lucid message and flawless content.

Over the past decade, I've used my skills to perfect thousands of investor letters, offering memoranda, white papers, and board presentations for clients like Rockefeller PA, TEDx, and the CDC—and I'm ready to do the same for you.

Before You Hire

Smart questions to ask before hiring…

Most of my clients are strong writers, which is precisely why proofreading matters. When you are close to your work, your brain reads what you meant, not what it says. I bring a trained, external set of eyes to catch the errors and inconsistencies you can't see, before your audience does.

Critical documents deserve more than algorithms. Automated tools catch most surface-level issues (e.g., grammar, spelling, punctuation) while missing context, meaning, and subjective details that impact your credibility.

I provide the human judgment, rigor, and confidentiality that an AI or spellcheck tool cannot.

See Services for details—or if you're still keen to use AI, check out AI Assist.

No. I preserve your tone and voice while highlighting only errors. You decide which changes to keep.

Yes. I specialize in complex documents where accuracy, clarity, structure, and consistency matter: technical reports, regulated materials, executive communications, and those with reputational or legal risk attached.

No one. I routinely work with sensitive, pre-release, and internal materials, and it is all reviewed privately and treated as confidential by default. Unlike many AI tools or agencies, I will sign an NDA.

I can generally handle last-minute, high-pressure submissions, but rush slots are limited and frequently become unavailable. Contact me, and I will communicate up front about whether I can deliver on your timeline.

Or, if you're really pressed for time, sign up for AI Proofread to get your document proofread in as little as 15 minutes.

Don't make a mistake; trust someone who catches yours.
