Fractional Marketing Leadership · Boston & Remote

Fractional Marketing Leader for Growth-Stage Companies

One senior owner for your entire demand engine, from strategy and paid media to HubSpot and the website that converts it all.

I've spent 17 years in marketing, including roles at edX, AOL, and Fidelity. Now I step in as the marketing leader growth-stage companies need before they're ready to hire one full time.

Based in the Greater Boston Area. Working with teams in Boston and remotely.

Expertise

Full-Funnel Demand Generation, Owned by One Leader

Most growth-stage teams buy marketing in pieces: an agency for ads, a freelancer for the site, someone part-time in HubSpot. Every vendor reports solid numbers, and pipeline still stalls. The leaks happen in the handoffs nobody owns. I run the whole system as one engine, so the ad click, the landing page, the CRM record, and the sales follow-up all answer to the same revenue goal.

Growth Strategy & Planning

A marketing plan tied to pipeline targets, with budget moved to the channels that prove they pay back.

Paid Acquisition

Google, Meta, and LinkedIn campaigns measured on qualified opportunities, so spend gets judged on revenue instead of clicks.

Marketing Operations & HubSpot

Lead scoring, routing, and reporting your sales team trusts. HubSpot CRM Certified.

Website, SEO, GEO & AEO

A site that ranks in Google, earns citations in AI search tools like ChatGPT and Perplexity, and converts the traffic it wins.

Where I've Led Marketing

Marketing Leadership at edX, AOL, Fidelity, and Growth-Stage Startups

Enterprise teams taught me process at scale. Startups taught me to ship with a small budget and no safety net. My clients get both.
