Petrella Phillips

What Petrella Phillips does

Petrella Phillips LLP is a privately held Certified Public Accounting firm headquartered in Brighton (Rochester), New York, serving individual and business clients across Western NY from three physical locations (Rochester, Dansville, and Geneva). The firm originated from John S. Petrella's accounting practice circa 1975, operated as Petrella & Petrella LLP for 25 years, and was re-formed in Fall 2012 when Thomas A. Petrella partnered with Michael M. Phillips to combine resources and specialty practices. The current team comprises 13 CPAs, 2 Enrolled Agents, and over 20 support staff operating from a 7,300-square-foot facility equipped with advanced tax preparation and research software, secure electronic communication, and global electronic filing capabilities.

The firm's service portfolio spans core tax preparation and planning, IRS and state tax authority representation, estate and trust tax preparation, and business consulting for clients from startup through retirement. Specialized capabilities added through acquisitions of independent firms include certified business valuation, audit reviews and compilations, in-house bookkeeping, and certified M&A advisory. Electronic payroll services are delivered through an outsourced partnership with Year Around Payroll Service, and the firm leverages CPA Connect membership for extended strategic planning resources.

Revenue is generated through professional services fees on a transactional basis: per-return tax preparation fees paid at pickup or in advance of electronic filing (required under IRS Circular 230), hourly rates for notice response and advisory work, and miscellaneous fixed fees for extensions and reprints. The go-to-market motion is sales-led and relationship-driven, relying on direct office consultations, professional network referrals, the firm website, and LinkedIn presence rather than paid advertising. Customer segments are diversified across individuals, corporations, partnerships, trusts, estates, not-for-profits, medical practices, real estate investors, dental practices, and startups, with no disclosed concentration in any single client or vertical.
