About Mary Gillen


I am a Web developer, writer, technical trainer and online marketer...all under one roof.

I have worked for myself since 1981. That's over 35 years experience in freelance commercial/technical copywriting, graphics design, online marketing, Web development and technical instruction development/presentation.

Web Development: 21 Years Programming Experience

I design and develop Web applications that serve, including responsive, 508-compliant and search engine-optimized Web sites. I am experienced in developing and producing Web-based content management systems that fit the work flows of organizations and give clients autonomy to control their own content. Over the years I have developed Web sites for large corporations, small startups, non-profits, associations, Federal government agencies and more. Clients include: National Institutes of Health, The World Bank, International Brotherhood of Teamsters, Cancer Research Foundation of America, American Pharmacists Association, McKinsey & Company and many others. Responsive design, search engine optimization, WCAG 2.0 A, AA & AAA compliance standards are always applied.

Copywriting: Since 1977

As we all know, copywriting is one of the most essential elements of effective online marketing and business communication. I have written hundreds of brochures, technical manuals, and Federal government RFP proposals. I also have lots of experience writing for the Web, and producing commercial business marketing copy for public and private organizations across the United States.
