Our attorneys

Paul S. Rafelson
Founder
Paul founded the firm and originates its M&A work. He also handles Amazon account matters, Prop 65 notices and compliance work. He is admitted in Florida (2005) and New Jersey (2006). He holds a J.D. and M.B.A. from Villanova, a B.B.A. in Accounting from UMass Amherst, and an LL.M. in Taxation from NYU.

Katherine (Katie) Dariano
Senior Counsel
Katie’s practice focuses on mergers and acquisitions, business transactions, complex commercial contracts and dispute resolution. She leads the firm’s M&A practice and is admitted in New York (2021).
Online Merchants Guild, the Supreme Court and Congress
Paul founded the Online Merchants Guild in 2018, a volunteer-led trade association run by and for Amazon sellers. It is the world’s first seller-run Amazon seller trade association.
Paul wrote the Online Merchants Guild’s amicus brief in South Dakota v. Wayfair at the U.S. Supreme Court (No. 17-494, 2018) as counsel of record. He submitted written testimony to the House Small Business Committee for its March 3, 2020 hearing on the Wayfair decision, and the Guild’s written statements to the House Judiciary Committee’s antitrust investigation of Amazon (2020) and its 2021 antitrust markup.
In the House Judiciary Antitrust Subcommittee’s October 2020 staff report (reprinted as Committee Print 117-8, 2022), the Guild was cited 13 times, more than any other outside group, on Amazon’s treatment of third-party sellers.
