Oakland-based accounting firm One River CPAs has acquired an Augusta firm, Gibson LeClair LLC, and is looking to continue growth. One River Director Jamie Boulette wouldn’t disclose terms of the deal Tuesday, but told Mainebiz the firm has retained all 11 members of Gibson LeClair, including principals Jeanne Gibson and Steve LeClair. Both now serve as directors, and One River now has a staff of 31. One River had 2019 revenues of $2.9 million, ranking the firm No. 11 in the state, according to the 2021 Mainebiz Book of Lists. Boulette projects the annual revenues of the combined firm to be about $4 million, which could move it up a few notches.
