A pair of Springfield-based certified public accounting firms have combined through an acquisition that closed this month.

Elliott, Robinson & Co. LLP has purchased HTSG CPAs and Advisors, according to a news release. Elliott, Robinson & Co. is the continuing name of the combined entity through the deal that closed for undisclosed terms on Nov. 1.

"Their firm’s values, reputation for excellence and dedication to clients align perfectly with our own," said Matthew Solidum, managing partner of ERCPA, in the release. "This partnership reflects our shared vision of growth through integrity, collaboration and exceptional service."

All HTSG CPAs employees are transitioning to employment at ERCPA. That includes firm leaders Stephen R. Gintz, who is joining ERCPA as a partner, and Donald L. Hagan and Leilani L. Hagan, who will start a phased retirement transition in 2026.

“Partnering with Elliott, Robinson & Co. allows us to continue offering the same trusted service our clients rely on, while expanding the resources and expertise available to them,” Gintz said in the release. “This decision was made with our clients’ long-term success in mind."

On Springfield Business Journal's September-published list of the area's largest CPA firms, ERCPA ranked No. 3 and HTSG CPAs ranked No. 10, based on number of local CPAs. For the list, ERCPA reported 25 CPAs and 48 total staff members, while HTSG CPAs reported five CPAs and 18 total staff members.

HTSG CPAs was created through the 2016 merger of O’Dell, Hagan & Co. LLP and Tucker & Co. PC, according to the release. ERCPA was founded in 1973.
