Lone Peak Dental Group, a Denver-based dental services organization, has sold to investment firm BlackRock, according to three sources familiar with the situation.

The deal closed on 13 December, the sources said.

Mergermarket previously reported that former Lone Peak owner Tailwind Capital collected final bids in its sale process last September, followed by a report earlier this week stating a deal was imminent. Mergermarket also reported in May that Lone Peak hired Baird to run the process.

Lone Peak generates EBITDA in the low-teens millions of dollars, as reported. It has been owned by investors including Tailwind since 2017.

The business supports dental offices specializing in pediatric care, orthodontics and oral surgery across 65 locations in 14 states. Unlike traditional DSOs, Lone Peak describes itself as a dental partnership organization (DPO) as it uses a doctor-owner model, according to its website.

Lone Peak, Tailwind and Baird did not respond to requests for comment. BlackRock declined to comment.
