Built on experience.
Oriented toward yours.
Turning complexity into clarity isn't just a tagline. It's a description of what supply chain leadership actually looks like when it's done well — and a fair summary of why Verant exists.
Biotech companies at every stage need senior supply chain leadership, and the options for getting it are limited. You can hire full-time and wait months for the right person. You can bring in a large consulting firm and receive junior staff doing billable hours. Or you can go without, and manage the risk.
Verant offers a fourth option. Senior, experienced supply chain leadership — embedded in your organization, working as part of your team, available without a full-time headcount commitment. And when the work calls for hands-on operational support alongside strategic oversight, we bring in experienced supply chain professionals who work within the same framework and to the same standard.
The firm was built on a career that spans early-stage clinical organizations and large commercial operations — building supply chain functions from nothing, managing global networks at scale, running S&OP for a commercial portfolio across multiple continents, and serving as the supply chain lead through some of the most complex regulatory timelines in the industry. Across small molecule, large molecule, cell and gene therapy, and mRNA vaccines. Across companies at every stage from seed-funded startups to large commercial biotechs.
What that accumulation of experience produces is judgment. The ability to look at a supply chain situation — whatever stage, whatever complexity — and know quickly what matters, what doesn't, and what needs to be built next.

Rhiannon Mello has spent her career at the intersection of science and supply chain — a combination that is rarer than it should be, and more valuable than most organizations realize.
Her path into supply chain began in the lab. Early work in cell culture development at Biogen — supporting BLA filings, process characterization studies, and tech transfers to large-scale manufacturing — gave her a scientific foundation that still shapes how she approaches every supply chain challenge. In biotech, supply chain decisions are never purely operational. They are scientific decisions, regulatory decisions, and commercial decisions simultaneously. Leaders who understand that distinction make better ones.
What followed was a career that has covered the full range of what biotech supply chain actually demands. Building clinical supply functions from scratch at early-stage companies. Leading global supply planning across a large commercial portfolio. Serving as Supply Chain Product Lead for one of the most complex and consequential launches in the history of the industry. And most recently, building and leading the supply chain organization at a late-stage company preparing for its first commercial launch — the kind of work that requires both strategic clarity and the willingness to do whatever it takes to get it right.
Across all of it, the through line has been the same: coming into organizations that need structure, building it, and leaving them more capable than she found them. That is the work Verant was built to do.
Rhiannon holds an MS in Engineering Management from Tufts University and a BS in Chemical Engineering from Northeastern University. She holds the APICS CSCP certification and is based in Topsfield, MA.
On the name
Verant comes from the Latin verare — to be true, to speak with accuracy. It's a name chosen for a practice built on giving clients honest assessments rather than comfortable ones.
The cairn in the mark carries a parallel idea. A cairn is a stack of stones placed on a trail by those who have passed before — not a monument, but a marker. Something left behind to help others find their way. That's a reasonable description of what good supply chain leadership does: it builds infrastructure, processes, and organizational capability that stays useful long after the engagement ends.
