Bellementis PLLC today announced its launch as a full-service boutique law firm designed to deliver sophisticated, integrated counsel across financial markets, emerging technology, litigation, regulation, and public policy.
Founded in Washington, D.C., Bellementis brings together senior government experience, top-tier law firm credentials, and deep technical fluency in digital assets, artificial intelligence, derivatives, fintech, cybersecurity, and modern financial infrastructure. The firm is built for the complexity and pace of today’s markets.
Bellementis is distinguished by its integration of proprietary AI-driven legal tools and a developing platform founded by Teresa Goody Guillén to enhance legal analysis, market intelligence, and client service in fast-moving, complex environments. Through its proprietary Tracker & Intelligence platform, the firm also provides complimentary public access on its website to advanced regulatory tracking, enforcement intelligence, legislative monitoring, and market analysis.
“Markets have outpaced traditional legal models,” said Founding Partner Teresa Goody Guillén. “Clients are confronting legal risk that is at once regulatory, technological, financial, and geopolitical. They need counsel capable of operating across those dimensions in real time. Bellementis was built as an integrated platform to meet that demand.”
The firm is led by internationally recognized financial regulatory and digital asset attorney Teresa Goody Guillén, former counsel in the Office of the General Counsel at the U.S. Securities and Exchange Commission and founder of the Digital and Innovative Markets practice at an Am Law 100 firm. Goody Guillén has been recognized by Chambers USA in Blockchain & Cryptocurrencies, named among Securities Docket’s “SEC Enforcement Elite,” and recognized by Washingtonian as one of Washington, D.C.’s “500 Most Influential People.”
