About Us

Bespoke Commercial Law Advice

Whether you are navigating a commercial dispute, reviewing a shareholder agreement, buying or selling a business, or protecting long-term business interests, our focus is simple: helping you make informed commercial decisions with confidence.

Led by Principal Solicitor Bryan Wong (with more than 10 years of experience in the industry), we combine legal expertise with practical commercial solutions. Clients work directly with experienced lawyers who understand that legal advice should support business objectives, not create unnecessary complexities.

A Value-Driven Approach to Commercial Law

Legal advice must always provide commercial clarity, not administrative friction.

CG Gillis & Co was built around a straightforward principle: clients should understand the legal risks, commercial realities and likely outcomes before committing significant time and or resources.

Our role is not to complicate decisions. Our role is to simplify decisions and help clients make informed ones. We assess legal issues through a commercial lens, balancing the cost of action against the likely business outcome. This approach allows clients to move quickly, confidently and with a clear understanding of their options.
