Plaskolite
Donald Dunn's Columbus family office deploys manufacturing wealth into industrial tech and real estate, anchored by a retained stake in Plaskolite Inc.
Plaskolite
Plaskolite was founded in 1950 by Donald Dunn as a small acrylic fabrication shop, eventually scaling into the continent's dominant producer of thermoplastic sheets. The founding fortune stems from the operating company, Plaskolite Inc., which the Dunn family controlled for nearly seven decades before selling a majority stake to Pritzker Private Capital in 2018, creating a significant liquidity event for the family office. The family's investment strategy centers on industrial technology and real estate. Post-transaction, the Dunns retained a meaningful minority position in the operating company via PPC's acquisition structure. The office deploys capital through direct deals and co-investments, with a known focus on advanced manufacturing, specialty chemicals, and commercial real estate assets across the Midwest and Southeast. A parallel philanthropic vehicle, the Dunn Family Foundation, operates separately and emphasizes education and community development in central Ohio (per public filings, 2023). The family office operates from Columbus, where the original manufacturing headquarters sits. The 2018 deal with Pritzker Private Capital—led by Tony Pritzker's investment firm—saw Charlesbank Capital Partners exit its own investment in Plaskolite, a transaction that valued the enterprise at roughly $1.7 billion (per Bloomberg, 2018). The Dunns maintain operational proximity to the business, with family members remaining on the board. The Dunn family office's structural differentiator is its continued embedded position inside the operating company post-sale. Rather than cashing out fully, the family retained board representation and a minority equity stake, linking the office's investment horizon directly to the ongoing performance of the industrial platform. This hybrid posture—partially liquid, partially anchored to a single operating asset—means the office's capital velocity shifts with the industrial cycle, a rhythm distinct from diversified portfolio family offices.

Frequently asked questions
Who runs investment decisions at Plaskolite's family office?
The Dunn family oversees investment decisions through the family office in Columbus, Ohio. Day-to-day management details are not publicly disclosed, consistent with the low-profile posture the family has maintained since the 2018 sale of the operating company. Family members remain on the board of Plaskolite Inc., keeping the investment office closely tied to the industrial asset's performance.
How is Plaskolite's family office related to Pritzker Private Capital?
Pritzker Private Capital acquired a majority stake in Plaskolite Inc. in 2018, with the Dunn family retaining a significant minority position (per Bloomberg, 2018). The family office's investment capital is tied to the proceeds and retained equity from this transaction. This relationship means the office's capital base fluctuates with the valuation of the underlying operating company.
Where does the underlying wealth come from?
The wealth originates from Plaskolite Inc., a thermoplastic sheet manufacturer founded by Donald Dunn in 1950. The company grew to become North America's largest private acrylic sheet producer before the family sold majority control to Pritzker Private Capital in 2018, valuing the enterprise at approximately $1.7 billion (per Bloomberg, 2018).
Does Plaskolite's family office maintain philanthropic structures?
Yes, the Dunn Family Foundation operates as a separate philanthropic entity focused on education and community development initiatives in central Ohio (per public filings, 2023). The foundation is legally distinct from the family's investment office but draws from the same wealth origin.
What investment stages does the office typically target?
The family office invests primarily in mature industrial technology companies and commercial real estate assets, particularly in the Midwest and Southeast United States. The post-2018 structure, with retained equity in the operating company, suggests a preference for control-oriented or significant minority positions rather than passive fund commitments.
Is Plaskolite structured as a single family office or does it operate more like a holding company?
The Dunn family office functions as a single family office, not a multi-family platform, with capital derived exclusively from the Plaskolite manufacturing fortune. However, its retained minority stake in Plaskolite Inc. gives it some holding-company characteristics, as the family's wealth remains partially tethered to an operating business's industrial cycle.
How does the office source deal flow?
Deal flow is presumed to come through the Dunn family's deep manufacturing network in the Midwest, relationships with private equity sponsors including Pritzker Private Capital and former investors Charlesbank Capital Partners, and the family's board-level participation in the plastics and industrial sectors. The office does not publicly market itself to intermediaries or co-investors.
