About Us.

Since its foundation, Sius Consulting has been 
focusing on result oriented & value driven consultancy aiming client satisfaction.

We believe there is no better approach to solve business challenges through internalizing our clients' objectives, priorities and agendas.


Our partners have a successful track record in multinationals and global consultancy practices and are among the first professionals focusing on forensics in the Turkish market. We care deeply about basing decisions on long term relations and benefits, rather than short term gains.

for your business, prospective investments, or potential business alliances.
