The firm is founder-owned and governed as an LLP with no external private equity, venture, or parent-company ownership. Leadership includes Michael W. Sullivan as Founder and General Managing Partner, Eric De Wames as Managing Partner, and Megan Sullivan as Senior Partner. There is no proprietary technology platform; the offering is human legal expertise delivered across a statewide physical footprint, supplemented by thought-leadership content used to drive inbound demand from HR and risk-management buyers.
