Career Trajectory and Previous Roles
Pieter van Welzen most recently served as a senior banking and finance consultant at CMS South Africa for six years before joining Thomson Wilks. During his tenure at CMS South Africa, he was instrumental in advising clients on significant financial matters, building upon his extensive career. His legal career began in 1990 when he started at Clifford Chance, a firm he would later rejoin. This initial period laid the foundation for his expertise in international finance. In 1998, Mr. Van Welzen moved to Freshfields Bruckhaus Deringer, where he spent eight years and was promoted to partner. This promotion marked a significant achievement, recognizing his contributions and leadership in the field. He returned to Clifford Chance in 2006, continuing his work as a partner in the firm, where he further solidified his reputation in banking and finance law. Mr. Van Welzen remained at Clifford Chance until 2020, at which point he departed to join CMS South Africa, bringing his wealth of experience to the South African legal market. His career trajectory demonstrates a consistent focus on high-level financial legal advisory roles within leading international law firms.
Firm's Recent Growth and Strategy
Thomson Wilks expanded its South African team in January 2026 through a merger with the former Durban office of Eversheds Sutherland. This strategic move integrated new expertise and resources into the firm's operations, significantly bolstering its regional presence and service offerings. The expansion in Durban followed a period of strategic growth for Thomson Wilks, strengthening its presence across key regions within South Africa and enhancing its capabilities to serve a broader client base.
In May 2026, the firm further augmented its Johannesburg team by adding consultant lawyer Roux van der Merwe. Mr. Van der Merwe joined Thomson Wilks from Schindlers Attorneys, bringing additional legal experience to the firm's capital. His appointment showed Thomson Wilks' commitment to attracting top legal talent and expanding its specialist teams. These appointments reflect Thomson Wilks' ongoing strategy to enhance its capabilities and broaden its service offerings across various legal disciplines and geographic locations within South Africa. The firm's proactive approach to recruitment and strategic mergers positions it for continued success and increased market share in the competitive legal landscape. The addition of experienced professionals like Mr. Van Welzen and Mr. Van der Merwe aligns with the firm's objective of providing full and high-quality legal services to its growing clientele.
