What Wilkin & Guttenplan, P.C. does

Wilkin & Guttenplan, P.C. (d/b/a WilkinGuttenplan or WG CPAs) is a privately-held, full-service accounting and advisory firm headquartered in East Brunswick, New Jersey, with a secondary office in New York City. Founded in 1983 by Ed Wilkin, CPA and Ed Guttenplan, CPA, the firm has grown from two founders to over 130 professionals organized across 12 industry-specialized practice groups serving middle-market companies, closely held businesses, community associations (condominiums, co-ops, townhomes, timeshares), professional athletes, financial services firms, healthcare practices, life sciences companies, manufacturers, real estate entities, not-for-profits, and high-net-worth individuals. The firm reports having served over 1,000 community associations and prepared over 1,000 tax returns for professional athletes since inception.

The firm's service portfolio spans three primary revenue streams: audit and assurance (annual audits, reviews, compilations, employee benefit plan audits, peer review); tax services (federal, state, international, and individual tax planning and compliance); and advisory/consulting services (business valuation, litigation support, M&A advisory, outsourced CFO/controller functions, family office services, trusts and estates, and technology consulting). Technology operations rely on industry-standard accounting software, with the firm positioning itself as certified trainers and installers of leading accounting applications. Marketing and lead generation are executed through thought leadership channels including a proprietary podcast (Future-Focused Advisory), webinar series, blog content, social media, and active participation in industry organizations such as the Community Associations Institute (CAI).

The firm operates under a professional corporation structure with Dan Fiorentino as Managing Shareholder, Deb Norwicke as COO, and Ed Guttenplan as Managing Shareholder Emeritus. Since 2012, the firm has been an independent member of the BDO Alliance USA, providing access to BDO's global network across 160+ countries. Growth has been driven primarily through tuck-in mergers (McDevitt & Company in 1997, Kleiman & Weinshank in 2018) and organic vertical specialization, with 2026 partner promotions signaling continued internal succession planning.
