In 1961, the firm's founder Dr. Philip Wong opened his first law firm, Philip K.H. Wong & Co. The business of that firm grew steadily over the next 30 years as Hong Kong transforms into an international business and finance centre and demand for legal services increases. In 1990, Dr. Philip Wong restructured the partnership and co-founded the present firm, Philip K.H. Wong, Kennedy Y.H. Wong & Co. (the firm), with his son Kennedy Ying Ho and daughter Ada Ying Kay.

In 1992, the PRC Ministry of Justice gave its approval to the firm to establish an office in mainland China. It was the first Hong Kong law firm to open an office in Shanghai.

The firm now comprises 11 solicitors, including 1 registered foreign lawyer admitted in the PRC. Everyone is committed to providing quality professional service to clients, working closely with them through careful and thoughtful planning, in order to achieve their goals while remaining sensitive to the control of costs and fees.

The firm has developed its China-related business since the early 1990s, handling many large scale PRC investment projects for clients. The firm also established business connections with major PRC enterprises, and was legal adviser to two companies which were among the first batch of PRC enterprises listed in Hong Kong in the mid-1990s.

The firm is a member of the International Lawyers' Group, a network of reputable law firms in major cities around the world, including North and South America, Europe, Asia and Australia. Member firms are committed to providing quality legal services in their jurisdiction to the others.

At the same time, the firm has entered into strategic alliances with law firms in other major cities of China to strengthen its capability to advise clients in the fastest growing economy of the world .
