A Yes! Partner, Sheldon heads up new-business development, strategic planning, brand positioning, key-messaging development, web strategy, and broadcast and interactive advertising production.

Sheldon began his marketing career in the early 1980s, with his formal education in business and marketing at New Hampshire College (now Southern New Hampshire University).

Fresh out of school, he worked as a retail buyer in the outdoor industry, where he gained significant experience developing and managing product lines and creating merchandising and sales strategies.

This prepared him for a position as Product Line Developer for national retail icon L.L.Bean. During his nine-year career there, Sheldon was responsible for developing, designing, positioning, and merchandising a variety of product lines and became L.L.Bean’s internal trainer for new-product positioning and key-messaging development.

From L.L.Bean, Sheldon moved into a position as Account Director for a full-service marketing agency in Portland, Maine. There, he drove strategic direction and project management for clients ranging from local non-profits to international category leaders. He developed key-messaging and positioning strategies for products and services marketed in North and South America, Europe, Asia, the Middle East, and Japan. A highlight of his time with this firm was his lead role working with The Organic Exchange to develop the international trust mark and messaging for organic cotton.

In 2004, Sheldon co-founded P.Doc Creative Partners, LLC, a full-service marketing and design firm located in Portland, Maine. In charge of new-business development, strategy, brand positioning, web architecture, and interactive media, Sheldon grew the business at a rate of more than 150% per year. P.Doc was one of the fastest growing and most highly recommended small- to mid-size agencies in Maine.

In 2007 Sheldon co-founded Yes! Marketing Group with Lisa Perkins to focus more specifically on the socially responsible, environmentally sustainable, and animal advocacy sectors.
