He invested in a second service truck instead.
That created two mobile service routes.
One covered Cypress and commercial accounts.
The other handled farm customers during planting and mowing seasons.
Tasha ran the second route twice a week and became so good at field diagnosis that customers sometimes asked for her by name.
A farmer once called the office and said, “Send that young lady who fixed the hydraulic noise last time.”
Denise put him on hold and smiled for ten minutes afterward.
Not everyone adjusted easily to seeing a young Black owner standing behind the counter of a growing equipment business.
Isaiah did not need every incident to become a lesson.
Most were smaller than that.
A supplier salesman walked into the warehouse, passed Isaiah at the front desk, and asked Tasha where the owner was.
She pointed back at Isaiah.
The salesman flushed and recovered quickly.
Another customer assumed Reuben had built the business and spent five minutes discussing pricing with him before Reuben said, “You’re talking to the wrong Callaway.”
A banker reviewing equipment financing asked Isaiah whether his father would co-sign.
“My father has never worked in this business,” Isaiah said.
The banker looked down at the application again.
“Grandfather?”
“Dead.”
“Partner?”
“No.”
The loan eventually went through based on financial statements, contracts, and collateral.
Isaiah did not celebrate changing the banker’s mind.
He celebrated getting a lower interest rate from another bank six months later because Callaway Reworks had established stronger credit.
Otis had taught him to notice what was still good inside a machine.
Denise taught him another version of the same lesson: do not let insult consume energy you need for structure.
“Correct the record,” she said. “Then keep moving.”
The company began hosting vocational students one afternoon a week.
The idea came from Harlow Technical High School after an agriculture teacher asked whether students could tour the warehouse.
Isaiah expected twelve teenagers for one visit.
Twenty-eight showed up.
Some had never seen a diesel engine open.
Some already knew more than they realized.
A quiet sixteen-year-old named Malik Barnes correctly identified cavitation damage on a pump housing before two adults standing nearby noticed it.
Isaiah asked how he knew.
“My uncle’s skid steer did that.”
“You ever work on one?”
“I watched.”
“Watching counts if you pay attention.”
The sentence sounded familiar.
Isaiah heard Otis inside it after he said it.
Callaway Reworks created a paid summer apprenticeship the next year.
Paid mattered.
Isaiah remembered jobs where “experience” was offered as if young people did not need gas money or lunch. He also remembered that his grandfather had been denied formal paths into dealership service work because people had decided what kind of mechanic belonged on a polished floor.
The apprenticeship accepted four students.
They started with safety, cleaning, documentation, and tool control.
