Earlier this month, Shackelford told city council Hardy was expected to add 75 new employees in coming years in exchange for the tax break.

“We are working through this process, ” expected to be approved by council once the expansion is complete, Shackelford said.

At the June 6 council meeting, after a celebration at the company facilities, Councilwoman Janie Ridd said Hardy workers willingly transferred from California, where home prices and the cost of living are higher.

“It was extremely obvious they wanted to be here,” Ridd said.

While confirming the willing transfers, Hardy indicated most of the new employees would be local hires.

“We currently have 90 employees in Springboro. We would expect this to double within about four years. The jobs that will be created will be mainly for the manufacturing, microbiology, biochemistry, engineering, quality assurance, and accounting departments,” he said in an email responding to questions about the expansion.

Our initial investment in Ohio is about $7 million. Most of this will be used to develop and complete our clean-room operations.”

Hardy sells medical devices and “culture media” used to diagnose infections in clean-room facilities designed to prevent contamination.

CFO Darla Prevish said the 2,600 products, produced in Springboro and Calfornia, are “food organisms eat,” enabling medical professionals to identify and treat patients’ strep and other infections.

Distribution is carried out from seven locations across the country in addition to Springboro and Santa Maria, where the company located after being formed in Santa Barbara in 1980.

Ohio operations moved to Springboro from Lima in 2011.

Prevish said the Hardy Family company bought the Pioneer property, which served as city offices during construction of the new city hall, from the city in 2011 and rented space to other companies until last year.

The company’s accounting, as well as distribution and about 30 percent of manufacturing, is already done in Springboro.

The company continues to do the bulk of its business in California.

“Our California headquarters currently employs about 280. However, we have are running out of space in that location. Also, the ‘business unfriendly’ environment and government over-regulation has made it difficult, if not impossible to continue our growth in California,” Hardy said.
