Credentials and experience

How we can help

The legal work that comes up at every stage — from incorporation to your next deal.

Most businesses don't need just one kind of lawyer. They need someone who can incorporate the company, draft the agreements, handle the deals, protect the IP, and step in as outside counsel when the harder questions come up. We do all of it.

Mayo Law works with founders, startups, small and mid-sized businesses, and established companies on the everyday corporate work that keeps the business running and the higher-stakes matters that shape what comes next. We act as transactional counsel for specific deals, as fractional general counsel for ongoing legal needs, and as cross-border counsel when your business has reach into the United States and beyond.
