The fire sale has officially begun. Six properties from the spectacular collapse of the LeFever Mattson real estate empire have quietly changed hands, marking the start of what may be the biggest property liquidation Sonoma Valley has ever witnessed—and that's saying something in a town where million-dollar deals aren't exactly rare.

Among the first to go were two Sonoma homes that tell the story of this $400 million unraveling: a 2,100-square-foot house on Cordilleras Drive that fetched $1.8 million for Kenneth and Jolinda Gladstein, and a slightly larger place on Third Street West that Mario Kovatchev snagged for $1.3 million. According to the Press Democrat, both sales came courtesy of Black Walnut LP, one of the many tentacles of the now-bankrupt LeFever Mattson operation.

When Buying Everything Goes Very, Very Wrong
Here's what makes this story particularly wild: between 2015 and 2023, indicted investment adviser Ken Mattson and his former partner Tim LeFever managed to acquire at least 120 properties in Sonoma Valley. That's in a town of just 10,000 people—do the math and you'll realize these guys were practically buying up the neighborhood.
Federal prosecutors apparently weren't impressed by this real estate shopping spree, slapping Mattson with nine counts of wire fraud, money laundering, and obstruction of justice in May. Their assessment? "A classic Ponzi scheme."
The partnership didn't just buy random properties either—they went for Sonoma's crown jewels. As the San Francisco Chronicle reported, their portfolio included iconic spots like the General's Daughter restaurant, the old Sonoma Cheese Factory, and that gorgeous Victorian home that belonged to a Civil War general's daughter. Talk about cornering the market on local charm.
Déjà Vu, North Bay Style
If this whole mess sounds familiar, well, you're not wrong. The North Bay has become something of a hotspot for spectacular real estate investment failures. The North Bay Business Journal documented another doozy involving the late Ken Casey's Professional Financial Investors, which ran a $330 million Ponzi scheme from Novato that fooled about 1,300 investors for three decades.
The parallels are uncanny—both operations involved massive real estate portfolios across Marin and Sonoma counties, both ended in bankruptcy court, and both used the same consulting firm (FTI Consulting) to untangle the mess. According to the North Bay Business Journal, FTI has gotten quite good at this particular type of disaster cleanup.
The Locals Fight Back
Sonoma residents weren't just sitting around watching their town get bought up piece by piece. A grassroots group called Wake Up Sonoma formed to keep tabs on the partnership's activities, and boy, did they uncover some uncomfortable truths.
The Sonoma County Gazette reported that the community organizing intensified after residents discovered the duo's connections to anti-LGBTQ organizations. Things got particularly heated when Stacy Mattson's Facebook posts came to light—posts that one local publication described as expressing "fear and loathing of gay people."
The revelation that the couple funded organizations labeled as hate groups by the Southern Poverty Law Center didn't exactly endear them to the famously progressive Wine Country community. Local businesses found themselves in the awkward position of explaining to customers that no, they didn't choose to rent from these landlords—they just got swept up in the buying spree.
The Great Unwind Begins
Now comes the messy part: figuring out how to liquidate a $400 million real estate empire while hundreds of defrauded investors wait to see if they'll ever get their money back. Attorney Debra Grassgreen of Pachulski Stang Ziehl & Jones has been hosting virtual town halls for investors, delivering updates that are probably not what anyone wants to hear.
The numbers are staggering: 175 properties in the bankruptcy portfolio, with more than 65 in Sonoma alone. As of July, 70 properties had signed purchase agreements, and 26 were actively on the market. The courtyard apartments on Studley Street have already sold to the Grasso Herrick Family Trust for $1.5 million, while properties in Vacaville, Citrus Heights, and Sacramento continue to close.
Justice, Eventually
Meanwhile, Mattson himself is dealing with some serious legal heat. The Napa Valley Register reported that FBI agents arrested him outside an Orangetheory Fitness gym in Napa—because apparently even accused fraudsters need to maintain their workout routines.
Federal prosecutors allege that Mattson ran his scheme from at least 2009 through 2024, using classic Ponzi tactics to keep the money flowing. He's currently free on $4 million bail while facing charges that could land him in federal prison for decades. The Securities and Exchange Commission has also filed a civil enforcement action, because why settle for one legal proceeding when you can have two?
What Happens Next
Three more Sonoma properties are already queued up for sale—a three-bedroom house on Third Street East, a three-unit property on Manzanita Road in Boyes Hot Springs, and another home on Larkin Drive. But that's just the beginning.
Properties held by KS Mattson Partners, the company Mattson operated with his wife Stacy, could add another 20 Sonoma properties to the liquidation pile. For a small town, that's a lot of real estate changing hands all at once.
The whole saga serves as a cautionary tale about what happens when investment schemes meet small-town real estate markets. For the hundreds of investors—many of them retirees who trusted their life savings to these partnerships—the liquidation process represents their only shot at recovery. Given that reliable records only go back seven years despite allegations of fraud dating to 2009, that recovery might not be what anyone was hoping for.
But hey, at least Sonoma's getting some of its iconic properties back on the market. Whether that's a silver lining or just another chapter in this very expensive lesson depends entirely on where you're sitting.
