Executive Strategy Grounded in Real Business Experience

Tamara O’Dea is a Fractional CMO, GIA Graduate, jewelry business owner, and marketing agency owner with more than 30 years of experience in business ownership, brand development, and marketing strategy.

Her background combines deep jewelry-industry knowledge with executive-level experience in brand positioning, customer acquisition, digital strategy, SEO, AI search visibility, email, television, radio, streaming, websites, and paid media. That breadth gives her the ability to evaluate the entire marketing picture rather than treating individual channels as isolated tactics.

Through Diamond Edge Marketing, Tamara provides senior-level marketing leadership for businesses—particularly jewelry and luxury brands—that need clearer strategic direction, smarter allocation of resources, and stronger coordination across their marketing efforts without the overhead of a full-time CMO.
