wordsmith

United States - Last active: 3 days ago - Tests: 3 - Portfolio: 1

I'm a gifted storyteller, dedicated to helping clients tell theirs. I say this unabashedly and with complete confidence. The proof, of course, is the words. Today, finding the right words is more important than ever, and I strive to under-promise but over-deliver. The name of my company says it all: words-are-my-biz And my philosophy is simple: The right words sell. The wrong words leave sales on the table. WHO AM I? I’m a professional writer living in Portland, Oregon with a lifelong passion for the power of the written word. I’ve written everything from novels to blogs, sales collateral to web content, ad copy to letters, business proposals to sales plans and training manuals. Not to mention a few thousand papers getting my four kids through high school and college. I love what I do. WHAT IS MY BACKGROUND? I bring more than thirty years of sales and marketing business management experience to every project, and by this I’m talking about major corporations to mid-size companies and start-ups, working in fields including software, real estate, law, publishing, advertising and services. I confess to having a particular fondness for high degree-of-difficulty challenges. JUST HOW DO I DO WHAT I DO? By asking questions, listening and considering what I hear, followed by collaborative brainstorming to develop a plan we both embrace with confidence and enthusiasm. As you seek synergy within your organization, I seek it with my clients. It pays huge dividends. The common thread is in finding the way to communicate more effectively, internally and externally, with staff, customers and prospects. The common challenge is in identifying the strengths, weaknesses, opportunities and unique competitive factors confronting each client. HOW CAN YOU LEARN MORE ABOUT ME? Visit my website, home to my novels, blog and publishing company, Old Dog Publishing.
