Wendell Achterberg
Founder · instruments and method
Eleven years calibrating measurement equipment for an aerospace supplier before he ever picked
up a torque wrench in a golf shop. He owns the instrument checks, the offset tables and the
argument about what belongs in which column on a card.
Takes driver blocks and full bag audits. Will talk about station pressure for longer than most
people want, which is either the best or worst thing about booking with him.

Rosalind Ifeanyi
Lead fitter · irons, wedges, short game
Ten seasons as an assistant professional across two clubs in central Oklahoma before she moved
indoors. She is the reason the wedge block tests four separate shots rather than treating a wedge
as a short iron with more loft.
Takes iron set blocks, wedge blocks and most junior sessions. Keeps sand from six local courses
in labelled buckets and considers this completely normal.

Tobias Renquist
Build room · tolerances and assembly
A machinist by trade, which shows up in a build room where everything is measured twice and the
before-and-after both go on the ticket. He built the loft and lie fixture that sits in the corner
because the commercial one had more play in it than he was willing to accept.
Handles every build, every bend and every bench job. Also the person who will tell you honestly
that a cast head should not be bent four degrees.

Junie Delacroix
Data and putting · the roll rig
Came from sports science rather than golf retail, and spent two years working with stroke
capture before joining us. She rebuilt the putter block from scratch around a roll rig and a
high-frame stroke camera after deciding a launch monitor was the wrong instrument for the job.
Takes putter blocks and gapping audits, and she is the one who checks every card for internal
consistency before it is handed over.
