Leading accounting, tax, and advisory firm SAX on Wednesday said it acquired Sewald & Anastasia CPAs, effective June 1.
This strategic alliance enhances SAX’s presence in Monmouth County and strengthens its real estate and private client service capabilities through the addition of seasoned experts Charlie Anastasia and Steven Sewald.
In 2023, Steven Sewald & Co. merged with Charles Anastasia to form Sewald & Anastasia. After nearly two years of strong growth in the south New Jersey market, the two lifelong tax professionals and softball teammates saw the opportunity of joining SAX as the next stage of the firm’s natural evolution. Sewald & Anastasia, a well-respected full-service tax and accounting firm with a 30-year legacy, has long served small to medium-sized businesses across key vertical markets, including construction, trucking, healthcare, and retail. This acquisition will bolster SAX’s capabilities in these vital sectors.
The integration includes an office located in Morganville, along with a talented team.
Charlie Anastasia, who serves as owner and managing partner of Sewald and Anastasia will join SAX as a partner. In addition, Steven Sewald will be joining the firm’s growing Private Client Services Practice as a director, bringing over deep industry knowledge and a strong dedication to delivering outstanding client service.
“This acquisition is strategic, as both SAX and Sewald & Anastasia are equally aligned in our service philosophies and our dedication to continued growth to best serve our clients,” Joseph Damiano, SAX managing partner said. “We are excited to welcome Charlie and his team to SAX. This partnership is a significant milestone for SAX, as our firm looks forward to leveraging this partnership to deliver enhanced value and innovative solutions to its clients across the region.”
“I am thrilled to join SAX and contribute to the firm’s already impressive legacy,” Charlie Anastasia said. “This acquisition represents a unique opportunity to combine our strengths and deepen our commitment to delivering exceptional service to our clients. I look forward to working with SAX’s Real Estate Practice and helping our clients navigate the complexities of the industry with innovative solutions and personalized guidance.”
As a result of this partnership, SAX is now a 62-partner firm with 367 total employees. The firm now has five offices between New Jersey, New York, and Mumbai, India, and has a remote team that spans 22 U.S. states.
