The merger, which became official on August 15th, will further expand and fortify blumshapiro’s position as the leading accounting, tax, and advisory firm in the region.

“We continue to look for opportunities to partner with leading firms who are strategically aligned with our firm’s focus on delivering innovative services and thought leadership to the market.
