Kolmac Outpatient Recovery Centers Merges With Concerted Care Group

In a combination of Maryland-based addiction treatment providers, Burtonsville-based Kolmac Outpatient Recovery Centers has completed a merger with Concerted Care Group (CCG), which is headquartered in Baltimore. Terms of the deal were not announced.

Founded in 1973, Kolmac operates 13 locations across Washington, D.C., Maryland, Virginia and Pennsylvania, providing services including psychosocial assistance and medication-assisted treatment (MAT).

Meanwhile, CCG provides outpatient integrated behavioral health services to individuals with substance use disorder (SUD) and mental health conditions. Founded in 2015, CCG operates three Maryland clinics in Baltimore, Brooklyn and Frederick.


“We are excited to partner with such a well-respected provider as Kolmac who shares our same vision for providing high quality, highly effective treatment to all patients in the outpatient setting,” CCG CEO Anton Kuznetsov said in a press release announcing the merger.

Kuznetsov will lead the newly combined company.

WindRose Health Investors, which is a lead investor in Kolmac, helped to initiate the merger along with investment firm Inclusive Capital Partners.


The combined Kolmac-CCG company intends to use its shared resources to expand into new markets, expand service offerings and to increase its market share in existing locations.

The combined business also stands to capitalize on more SUD treatment opportunities, as the Centers for Disease Control and Prevention (CDC) announced Wednesday that provisional drug overdose deaths rose almost 30% last year to over 93,000, the largest number on record.

​​”As a part of Kolmac’s growth strategy, we identified CCG as a very attractive, complementary business that would greatly accelerate Kolmac’s entrance into the government pay market within Kolmac’s existing geographic footprint,” Curtis Lane, a WindRose founding partner, said in the press release. “We believe that the combined business is a unique platform that provides the complete continuum of substance use disorder care entirely in the outpatient setting to all individuals, regardless of income levels or treatment preferences.”
