## About

Kenneth R. O'Donnell Jr. founded Colton Capital Partners in 2011 to manage capital generated by the O'Donnell family's multi-decade residential development and homebuilding operations across Houston's Memorial, Tanglewood, and River Oaks neighborhoods. The Houston-based office invests the family's own balance sheet, drawing on an operator network that includes former business partner Cornelius Dupre, with whom O'Donnell previously built oilfield service companies at Dupre Interests. The firm targets equity investments of $0.1 million to $20 million, covering buyouts, management buyouts, succession transitions, and growth-stage capital across energy, manufacturing, and service industries. Past portfolio names confirm an operational tilt toward oilfield services: Conquest Completions Services provided coiled tubing and completion fluids in the Eagleford and Permian before its 2017 sale, and Great Northern Midstream operates a 132-mile crude oil pipeline and rail terminal in the Williston Basin. Beyond energy, Colton backed Bellicum Pharmaceuticals through its clinical-stage IPO on Nasdaq and invested in Cadence Bancorp, a Houston-based bank holding company that scaled to over 95 locations and $7 billion in assets. The office also co-invests alongside other Houston family offices, including Doug Foshee's Sallyport Investments. Colton manages an active portfolio that extends to commercial real estate via Gordon Cornerstone Partners, a Midland shopping center, and Allen Harrison Company, a mixed-use developer founded by William Allen Harper and Paul Harrison Forbes. The family maintains direct ownership of O'Donnell Family Custom Homes, oil and natural gas royalty interests, and a sailboat racing program tied to the Houston Yacht Club. On the philanthropic side, Margaret O'Donnell serves as Secretary of the Houston Philanthropy Circle. The firm's most recent disclosed deployment includes funding the startup of an oilfield fluid logistics company that exited to a NYSE-traded firm. Unlike multi-generational family offices that build diversified fund-of-funds stacks, Colton operates more like a permanent-hold operating company — the family's residential homebuilding roots in Houston impose a durable in-region sourcing advantage, particularly in energy-services and industrial roll-ups where operator relationships are inherited from Dupre Interests and the broader Houston builders' network.

## Questions

### How does Colton Capital Partners source its deals?

The firm sources through intermediaries, business owners, industry executives, and independent sponsors, leveraging deep relationships in Houston's energy and homebuilding ecosystems. Longstanding memberships in the River Oaks Country Club, Houston Yacht Club, and Greater Houston Builders Association reinforce a local, network-driven origination model. Past co-investments with Sallyport Investments confirm close ties to other Houston family offices.

### Does Colton fund only energy deals?

No, historical holdings span financial services (Cadence Bancorp, over $7 billion in assets), healthcare (Bellicum Pharmaceuticals, a Nasdaq-listed biotech), and commercial real estate (Gordon Cornerstone Partners, Allen Harrison Company). The concentration in energy services reflects the O'Donnell family's operating DNA and regional Houston advantage, not a formal mandate.

### How is Colton's portfolio structured between active and passive investments?

The firm divides holdings into active and passive portfolios. Active investments include controlled operating companies like oilfield service firms, while passive investments cover royalties, real estate, and equity stakes in public companies such as Bellicum Pharmaceuticals. Gordon Cornerstone Partners, the Midland shopping center, and oil and gas royalty interests operated through Royalty Interests Partnership represent the passive side.

### Where does the O'Donnell family wealth originate?

The O'Donnell family built its wealth through residential real-estate development and custom homebuilding across Houston's most affluent neighborhoods, including Memorial, Tanglewood, and River Oaks. This homebuilding legacy spans multiple decades and remains active through O'Donnell Family Custom Homes. Colton Capital Partners was established in 2011 to manage the proceeds and reinvest them into private companies.
