The operator of a Twin Cities company has admitted in court that he cheated clients out of hundreds of thousands of dollars in down payments by falsely pledging to install in-ground swimming pools, then spending some of the windfall on gambling, child support and a horse and saddle.

Charles R. Workman, 40, who owned MN Crete Pools, a Prior Lake company that marketed pools throughout the Twin Cities area, pleaded guilty in U.S. District Court in Minneapolis to wire fraud in connection with the scheme that enriched him by more than $820,000 in 2021 and 2022.

Workman remains jailed without bail ahead of sentencing, which has yet to be scheduled.

The plea agreement between the defense and prosecutors notes that federal guidelines call for sentence ranging from 2¾ to just shy of 4½ years in prison. That said, federal judges have full discretion when sentencing defendants and are not bound by the guidelines calculation.

Workman lived on a 9-acre spread in Prior Lake. The 4,200-square-foot home included an in-ground heated pool in the back yard and a horse stable, the real estate listing noted.

The property sold in late 2022 for $876,000, according to county property records. Workman’s estranged wife, Jennifer Workman, told the Minnesota Star Tribune that they defaulted on the loan, were evicted and made no money from the sale.

According to the charges:

Workman collected down payments and promised to install a pool that same year, but then failed to complete the project. At times, he told multiple clients he only had one more spot on his construction schedule as inducement for them to make a down payment.

Workman gave clients various reasons for their project’s delay including the COVID-19 pandemic, the weather or equipment shortages.

The scheme allowed Workman to make $3,000 in child support payments, spend $18,000 at a casino and more than $6,000 on a horse and saddle.

The Minnesota Attorney General’s Office won a judgment in January of more than $1.1 million after suing Workman in 2022 for using “deception and falsehood” through his scheme to dupe 17 Minnesota families he signed up for pool projects that he failed to complete or even start.

Workman also operated other businesses related to concrete, according to state records. The Better Business Bureau received several complaints about MPLS Concrete Restoration that alleged Workman collected deposits for projects that were never begun or finished, or were about the work being done poorly.

“Charlie came to my house, and a contract was signed for the total amount $8,000” for a driveway, read one complaint filed in November 2021. “Informed them and sent pictures of concrete flaking and peeling. During this entire experience, I have numerous texts saying how they will be here to do the work and never showed up.”
