What Antheil Maslow & MacMinn does

Antheil Maslow & MacMinn, LLP (AMM Law) is a privately held, full-service law firm founded in 1992 in Doylestown, Pennsylvania, by William L. Antheil III, Susan A. Maslow, and William T. MacMinn. The firm provides legal representation across 13 practice areas — Business & Finance, Employment, Estates & Trusts, Family Law, Health Care, Litigation, Mediation, Mergers & Acquisitions, Nonprofits, Personal Injury, Real Estate, Zoning & Land Use, and Estate Litigation — serving national corporations, middle-market companies, entrepreneurs, family-owned businesses, high-net-worth individuals, and 501(c)(3) nonprofit organizations at federal, state, and international levels.

The firm operates with standard law firm technology infrastructure, including document management systems and legal research platforms, with no proprietary technology or AI/ML capabilities disclosed in the available data. Its workforce consists of approximately 18-20 attorneys listed on the firm website, having grown from three founding partners to a multi-partner LLP that occupies an owned and expanded two-story headquarters at 131 W. State Street, Doylestown.

AMM generates revenue exclusively through professional legal services fees, employing hourly billing, fixed-fee arrangements for specific matters, and retainer engagements for ongoing client relationships. Pricing is quote-based and not publicly disclosed, with rates varying by practice area and attorney seniority. The go-to-market motion is sales-led and relationship-driven: attorneys develop deep long-term client engagements directly, supported by a marketing mix that includes the firm's website and blog content, leadership participation in bar associations and the Central Bucks Chamber of Commerce, community involvement and pro bono work, and earned media through Super Lawyers, Best Lawyers, and ALM recognitions. No institutional investors, private equity ownership, parent company, or M&A activity has been identified; the firm has remained an independent LLP throughout its 33+ year history.
