A portfolio company of Sawtelle-based Corridor Capital has acquired a healthcare marketing services business in Maryland as part of a broader effort to scale the firm nationally. 

Corridor’s Specialty Marketing & Communications Holdings, which is headquartered in La Grange, Ill., announced Wednesday that it acquired Dreamscape Marketing, a Columbia, Md.-based digital performance agency that specializes in health care marketing. 

Terms of the transaction were not disclosed. 

“We are a significant player in this sector,” Craig Enenstein, chief executive of Corridor Capital, said. 

Specialty Marketing is considered a platform company for Corridor, which means it uses that company as a foundation to add tuck-in acquisitions, such as Dreamscape.  

Overall, Corridor has nine platform companies in its portfolio, Enenstein said.

Specialty Marketing was acquired by Corridor in 2018 but renamed as SPM Group in January 2020 following the addition of the Ellicott City, Md.-based Web Services division of Centretek Solutions, another health care marketing business that specializes in web design. 

The addition of Dreamscape enhances SPM Group’s digital capabilities and firmly establishes the SPM Group as a leader in behavioral health, addiction recovery, large group dental and senior care sub-sectors, Enenstein said.

The combined business gives SPM Group revenue of more than $50 million, he said. 

SPM Group has partnered with more than 300 hospitals, health systems, and health-related businesses to develop their brands. 

Dreamscape, which was founded in 1983, has specialized in digital marketing of health care services and organizations since 2005. It serves more than 700 health care operators and has designed more than 1,000 custom websites for clients. 

A year ago, Corridor Capital raised a $118 million fund to target businesses to buy with $2 million to $8 million in earnings before taxes. 

Corridor Capital was founded in 2005 and has roughly $200 million in assets under management.
