Firm Overview:

The firm was started by Mark D’Alelio with a focus in providing practical and business related legal services to assist clients in navigating through local regulations and practices in ASEAN, with a particular focus in Thailand, Myanmar, and Vietnam.

The firm’s unique selling proposition is we listen to our clients needs and partner with them in their business by administering compelling legal and practical solutions to meet their requirements.

Put simply, we believe there are many ways in acting as a legal adviser, but we feel strongly, that a bigger firm does not necessarily equate to providing a better service or response. We administer our business by putting our clients at the forefront by providing dedicated support with a singular focus in helping our clients meet the requirements of doing business in ASEAN.

That means we provide more for less to our clients.
