Maya Ellison
Managing Partner
Eighteen seasons across discrete manufacturing and fulfillment. Obsessed with rhythms that outlast sponsors.
01 · Crew dossier
We survey before we advise.
Fieldstone was assembled by people who had already carried plant, network, and P&L weight. The firm exists to rebuild bearing systems—not to narrate transformation.
A
Why the name
Fieldstone walls are quiet engineering.
No mortar theater. Fit, weight, weather. That is the standard we hold for operating design: if a rhythm needs our personality to survive, it is unfinished.
B
How we show up
Where the work happens
Floor walks, shift handoffs, live reviews. Decks are tools—not the deliverable.
Artifacts over dependency
Decision maps, visual controls, cadence packs a supervisor can run without calling Boston.
Metrics with bite
If a team lead cannot explain a number in one sentence, it does not drive behavior. We prune until it does.
