About

I've been working in HubSpot for eight years, across every hub and tier.I've built portals from scratch at in-house companies, served as the sole marketing technologist on lean teams, and managed enterprise-level engagements at a top-five global HubSpot Diamond Partner agency.Today I work independently with a small roster of clients on ongoing contract and fractional engagements.I know what a well-architected portal looks like, I can build one myself, and I can explain it clearly to the people who use it every day.If your company needs deep HubSpot expertise without a full-time hire, that's exactly what I'm set up to provide.

Portal Architecture

Before you can administer a portal well, it has to be built well.
I design and build HubSpot environments from the ground up.Custom properties, pipeline structures, object relationships, lifecycle stages, and automation frameworks that scale as your business does.If you've inherited a messy portal or are starting fresh, this is where we start.

Portal Administration

Ongoing admin support to keep your portal healthy, accurate, and running well.That means maintaining workflows, managing users and permissions, cleaning up data, and auditing what's broken. The work that keeps everything running the way it's supposed to.

Migrations & Data Mapping

Moving to HubSpot from Salesforce, Zoho, Dynamics, or another CRM?
I handle the full process. Field mapping, data cleanup, deduplication, and a clean cutover.Most migrations come down to getting the data right before the move. That's where I focus.

HubSpot Training

HubSpot is only as useful as the people using it.I train marketing and sales teams on the tools they're actually using. Not a generic overview, but hands-on instruction built around your portal, your processes, and your team's specific gaps.That includes onboarding new users, running workflow-specific sessions, and documenting best practices your team can reference after we're done.

AI Usage & Context Training

Most teams don't have a clear picture of where they actually stand with AI.I use a framework that maps complexity to what your team actually needs — from basic chat and projects up through skills and plugins for more sophisticated workflows. I make sure we only add complexity when it's genuinely needed.
At every level, the issue comes back to context. Give an AI too little and it retreads ground it should already have — you end up re-explaining what it already knew. Give it too much and outputs drift; quality drops fast.

I can help your team find where they actually are, close the gaps, and build the habits and assets that keep outputs consistent and costs predictable.

Email Marketing

Campaign strategy, template builds, list segmentation, and ongoing send management.I also focus on the health of your sending program. Warm-up strategy, list hygiene, and improving deliverability through better segmentation.If your emails aren't reaching inboxes or your program has gone stale, I can help get it back on track.

Industries I've Worked In

My experience spans a range of industries and company types. I've worked in-house as a marketer, embedded with agencies, and supported nonprofits, public benefit corporations, and early-stage startups. The knowledge I've built over eight years is broad enough, and my approach flexible enough, that I can adapt to the industry or situation in front of me.

Not seeing your industry? That's not a barrier.
