Our Team

Four People, One Deflection Board

Each fitter on staff holds professional club fitting certification and logs regular hours running the bench equipment themselves — not just reading the printouts.

OM
Founder & Lead Fitter

Owen Marsh

Built the studio's original deflection board setup and still runs most driver and iron fittings personally, with a focus on spine alignment work.

SR
Senior Fitter

Sophia Renwick

Handles the majority of iron and wedge fittings, specializing in frequency matching across full sets and dynamic lie measurement.

TO
Putting Specialist

Terrence Okafor

Runs the putting bench using a dedicated stroke-path capture rig, with particular attention to setup posture and face balance.

LV
Master Club Builder

Lena Voss

Oversees the build shop, verifying every finished club against its frequency and swingweight target before it leaves the bench.

Continuing Certification

We Keep Studying the Board, Not Just New Products

Alongside annual manufacturer certification updates, the team reviews board and range data from the studio's own session archive every quarter — so our internal fitting notes improve as the dataset grows, not only when a new head shape launches.
