Sustained Quality, a division of Peoplelink, acquired EHD Technologies, a Brentwood, Tenn.-based firm that provides quality assurance services. In addition, a significant portion of EHD’s business is related to talent acquisition. EHD ranked on the 2015 list of fastest-growing staffing firms.

“The addition of EHD to Sustained Quality’s business lines gives the new combined company a strong foundation in the quality assurance industry,” said Jay Mattern, president and COO of The Peoplelink Group. “The combination of EHD and SQ will move us forward quickly in terms of competitive position and the ability to provide additional quality assurance services to our customers. It’s truly a win-win in every sense of the word.”

The transaction closed Feb. 7; terms were not disclosed.
