We Build Relationships and Consistently Add Value to Our Clients Who  Work With Us...
Proud Supporters of the IKTVA Program

We are firm believers of supporting the countries and local population in the locations we work, which is why we are advocates of Saudi Aramco's In Kingdom Total Value Add (IKTVA) program, designed to drive additional domestic value creation in a rapidly changing economic environment, fostering future prosperity. We believe improving the localisation of our team members will not only benefit Saudi Arabia, but further diversify our team and increase the value we provide to our clients.
