Scientific Communications



Science editing

Whether it's polishing a paper for journal or magazine submission, refining website content, or writing technical notes or white papers, I'll make sure your information is well-organized and accurately conveyed with graphics that illustrate the information effectively and convincingly. I'll work with you to ensure that your paper is stylistically compatible with your chosen publication requirements.

Technical writing & editing

I have years of experience writing and designing manuals, tutorial guides, specification sheets, product brochures, and on-line help documentation for scientific instruments, components, and software. I’ll ensure that your documents are accurately presented and easy to understand.

Marketing communications

The best products in the world won't make an impact without effective marketing collateral. Hallenburg Communications will collaborate with you to develop marketing materials that get your products the attention they deserve at a price you can afford. 

Website project management

Your website is one of your strongest marketing tools for your products or services — and a direct line of communication with your customers. Hallenburg Communications will create new content, refresh and polish your current content, organize your information to maximize "usability," correct errors, enhance your visual presentation, and step-up your search engine visibility (SEO). 

I work with talented web designers, programmers, graphic designers, and illustrators to offer complete development and production services for scientific documents and websites.

How I Work

I work with you or your subject-matter experts to communicate your information accurately and effectively. Rates are calculated on either an hourly or project basis. Editing rates reflect the level of editing (substantive vs. light) required. Work can be arranged on a single project basis or as ongoing communications support. Call  503-867-7211  or email me to discuss your project.
