What Rock Mountain Capital buys
Rock Mountain Capital is a New York private equity firm founded by David Stonehill, a former Carlyle partner. It invests in three areas: consumer goods and services, consumer-facing healthcare services, and business services. It looks for North American companies with $3 million to $25 million or more of EBITDA and puts in $10 million to $100 million or more of equity. Together with its partners it has invested more than $600 million. It is flexible on control: it will take a majority, share control, or buy a structured minority stake, and its holdings show all three.
Add-ons drive much of its growth. Chord Specialty Dental Partners, the pediatric, orthodontic and oral surgery group it first backed in 2021, has made nine since then. Its newest platform is International Sports Management, from June 2025. A company under $3 million of EBITDA is most likely to meet Rock Mountain as an add-on, such as a specialty dental practice joining Chord or a household brand joining PurposeBuilt Brands or VCM Products.

Greymont’s take
How Rock Mountain Capital fits a seller
Rock Mountain suits founders of consumer brands, specialty healthcare practices and business services companies who want an active partner but may not want to give up control. Its holdings include majority, joint control and minority positions, so the structure is open to discussion. For dental specialists, it is a realistic route through Chord, which said it would preserve clinical autonomy when Dr. J Pediatric Dentistry joined in 2025.
The firm describes its capital as patient, and its portfolio page shows no exits, with the oldest holding dating from 2020. That can suit an owner in no hurry, but anyone rolling equity should ask how and when it expects to sell. Its website names no fund and counts invested capital across the firm and its partners, so also ask who else would be on the cap table and where the equity comes from.
Questions owners ask
Does Rock Mountain Capital buy dental practices?

Will Rock Mountain Capital take a minority stake?
Yes. Its site lists structured minority deals alongside majority and joint control. It holds a minority position in GeoLinks and joint control of PurposeBuilt Brands, where a group it co-led bought a 48% stake from Carlyle in 2022.
