    Professional Dental Writer

    United States - Portfolio: 5

    As an experienced dentist and writer with a formal background in psychology, I’m able to offer unique benefits on a variety of projects. I'm the primary content and blog writer for one of the biggest dental marketing companies in the Northwest, and a partner in a dental consulting company. Our client base includes dozens of top tier practices that demand exceptional content on many levels. I've also applied my psychology background to hone patient communication skills and develop numerous patient education documents. I consider this skill a key component to the 300% growth our practice experienced during the past 10 years with little external marketing. Whether you're reaching out to patients or dental professionals, I can help you connect, build trust, and draw a response.

    Copy Editing To Make Your Words Hit Home

    United States

    Whether you represent a business, institution, or profession, market your own products or services, or want to share your ideas with the world, you'll get a leg up on the competition by producing written communications or documents that reflect competence and professionalism. As a skilled and proven writer/copy editor, I can help you achieve those standards by improving the organization, paragraphing, and transitions in your text for better flow, and by optimizing sentence syntax and word choice for maximum clarity of meaning, sharpness of expression, and impact. I'm eager to help you make your words hit home in pursuit of your goals. You can be sure I'll work with you closely until you are satisfied that the finished product will in fact achieve the purpose you intend. And I'll do so at an attractive fee. As a freelancer now retired from corporate and agency employment, I seek this work not principally for the money, but to stay involved in an activity I very much enjoy.
