Boston-based Bain Capital Double Impact has acquired Durham-based Arosa LLC, an in-home health care company, for an undisclosed amount.

Arosa was purchased alongside Los Angeles-based LivHome Inc. with the intention of combining the companies.

Bain Capital Double Impact is the investing branch of Bain Capital.

Arosa was founded in 2012 and offers in-home care, pediatric therapy and staff across central and eastern North Carolina.

Since 1999, LivHome provides in-home health care and care management to residents of California, Illinois and Texas.

The combined company will be led by Ari Medoff, the CEO or Arosa.

“The marriage of these two companies, combined with Bain Capital’s extensive experience supporting health care providers, presents a unique opportunity to transform the in-home care industry,” said Medoff in a statement.

Medoff is a graduate of Duke University, Harvard Business School and Harvard School of Government.
