What DHJJ does
DHJJ is a private, for-profit accounting and professional services firm headquartered in Naperville, Illinois, United States. Founded in 1974, the firm operates across three core service lines: audit and accounting, advisory, and tax services, serving U.S. businesses as its end customers. With a workforce of 101-250 employees, DHJJ occupies the mid-tier of the regional accounting market, positioned between small local practices and large national firms.
The firm does not disclose a proprietary technology platform, products, or productized services in the available source data; the offering is structured around traditional professional services delivery by licensed practitioners. No pricing model, customer roster, geographic footprint beyond the Naperville headquarters, or partner-level leadership detail is publicly disclosed in the input, and the firm's primary web property returned a verification/loading screen without substantive content during data collection.
The revenue model follows the standard professional services construct: billable hours and fixed-fee engagements across compliance (audit, tax) and advisory work for business clients. No information on customer segments (enterprise vs. SMB mix), distribution channels, marketing approach, partnerships, awards, or ownership structure is available, leaving the firm's commercial posture and competitive positioning largely inferable only from its longevity and service line breadth.
