With more than 25 years of experience, Sirkien has worked alongside directors and executive teams across a wide range of industries, supporting companies to meet their statutory obligations and operate with strong, effective governance.

She holds a BLC degree from the University of Pretoria and an LLB from UNISA, and has spent her career working at senior levels in both listed and private companies. Over the years, Sirkien has attended countless Board and Committee meetings, helping to guide discussions, ensure regulatory compliance, and translate governance requirements into workable, real world solutions.

In 2026, Sirkien qualified as a Certified Director with the Institute of Directors in South Africa (IODSA). This qualification reflects her deep understanding of what it truly means to serve on a Board — from fiduciary duties and ethical leadership to strategic oversight and accountability. For JSS clients, this means they benefit from advice that is not only technically sound but also grounded in how Boards actually work and what directors need to succeed.

Sirkien is valued for her plain English approach to governance, her attention to detail, and her ability to act as a trusted sounding board for directors. Through JSS, she and her team help Boards stay compliant, organised, and confident — so they can focus on leading their businesses effectively.
