Greg Gonser, Fractional Chief Marketing OfficerGreg Gonser, Fractional Chief Marketing Officer

Fractional Chief Marketing Officer

Marketing needs leadership.

Senior marketing leadership for organizations that need strategy, direction, coordination, and accountability without hiring a full-time CMO.

Your goals lead

Your business comes first.

Before I recommend anything, I learn your company and how it really works. Your goals, your budget, and your needs drive the plan.

More about the process

Hands-on

I’ve done the work I’ll be guiding.

From web strategy, SEO, GEO, social media, and Claude Code to TV, radio, PR, video, audio, vehicle wraps, and signage. I know what a finished product looks like.

You probably don’t need more marketing.

Most organizations already have vendors, platforms, and plenty of activity. What’s missing is one senior person making them work together toward something the business can measure.

Career perspective

I’ve sat in a lot of seats.

I’ve recruited, managed accounts and sold, advertised, led marketing teams, and built an agency. Each seat taught me something the next one needed. Now I put all of it to work as your senior marketing leader.

Three engagements, in depth.

Designed graphic: patient inquiries up 24% while site sessions rose 6%, with no ad budget

A private specialty medical practice

A 60-year, four-location specialty medical practice needed more patients from the website it already had, and a strong launch for a new office, without an advertising budget.

Greg led marketing strategy and creative for the practice: content, search, listings, social, video (doing all the audio editing himself), PR, and visibility in AI search. The engagement ended in summer 2026 when the practice changed agencies.

A controlled-environment builder and its star acquisition

A five-year relationship spanning a post-acquisition brand and demand integration, along with its acquired sister company. The first piece of work was securing ownership of the client’s own domain.

Greg led brand and demand strategy across both companies: vertical-by-vertical content, a capture form for every market, automation, video, sales enablement, and search and AI visibility. He also drew all of the animation artwork digitally in Adobe Illustrator and animated it himself.

A Maine flavoring maker, founded in 1906

A Maine vanilla and flavoring maker founded in 1906 was profitable but stagnant: a product customers loved and could not find online, with no website and no social media. The family needed it findable again without losing the heritage that made it worth finding.

Greg built the digital foundation from zero: website and online store, social media, brand and logo renovation, relaunch PR, video, and shipping-carton design. He worked alongside the family, who led operations and retail.
