About

I've been working in HubSpot for eight years, across all five hubs and every pricing 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.That background means I can operate at multiple levels.
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

There is a lot of uncertainty around how to use AI tools effectively. I can bring a framework that cuts through that, showing you how to get the most out of where you are today and when it makes sense to move to the next level.The big issue for most users is context. Not understanding how context windows work, what happens when they fill up, and how conversation size affects output quality leads to higher costs, worse results, and a lot of unnecessary frustration.

I can help your team figure out where they actually are, get them to where they should be, and build the context habits that make your outputs consistent and your 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.
