Top 50 Firm BPM LLP announced that it is expanding into Los Angeles County by adding in Rossi LLP, a full-service CPA firm in Long Beach, effective Nov. 1.

Terms of the deal were not disclosed.

“This year has been one of many changes, and thankfully many positive ones for BPM and our new team in Long Beach,” said BPM CEO Jim Wallace in a statement. “We continue to look for business combination partners who are dedicated to providing our clients, community and colleagues with wow experiences, even during uncertain times.”

Rossi LLP, which was founded in 1984, offers accounting, auditing, tax, consulting and forensic accounting services to clients across the country, with a concentration in Southern California.

“With this combination, we are extremely well positioned to expand our capabilities and give our clients access to a large network of experts and resources that a local firm just cannot provide,” said Al Rossi, who is joining BPM as of counsel, in a statement. “BPM’s stellar reputation for its client service and acuity in specialty services means more opportunities to assist businesses at any stage of their lifecycle, from startup to wind-down.”

BPM ranked No. 46 on Accounting Today’s 2020 list of the Top 100 Firms, with annual revenue in 2019 of $117 million. In October, it merged in NetSuite reseller Caravel Partners, and earlier in the year, it added Warnick, Maestas Maroney, a firm in Irvine, California. Last September, the firm merged in Adhere, a cybersecurity firm in Fairfield, California. In August, BPM merged in CPA Consulting, a firm based in Bellevue, Washington, and in January added Croce Company, a firm in Stockton, California.
