About Mark
Biography
At Castlegate Law, we combine decades of legal expertise with a commitment to transparent, fixed-fee services tailored for startups, creatives, and growing businesses.
Castlegate Law was born from firsthand experience—decades of it—navigating the challenges of both private practice and executive in-house legal roles. The founding vision was simple: modern businesses deserve legal services that are as clear, agile, and strategic as they are.
Castlegate was built to rethink what legal representation looks like. No hourly billing. No mystique. Just fixed-fee, business-aligned legal counsel that fits the way founders, creatives, and companies actually operate.
That vision started with our founder, Mark S. King, Esq., a seasoned General Counsel and Chief Legal Officer. But it’s now carried forward by a growing legal team committed to transparency, responsiveness, and results.
