  • I have been working with Mahdi for more than a year now and enjoyed every day we have a chance to interact. Mahdi is a very knowledgeable and considerate person and I am proud of being his supplier. As many of my customers from time to time run into resource or capacity challenges, Mahdi is one of the first people that I turn to and recommend as an advisor. The feedback I have received from every one of these opportunities has been tremendous. I look forward to many more successful projects out there.  

    Filip Kuttner – Intercad

  • ‘We have been using Kohan Services for the past 12 months on a number of highly technical, performance critical design and engineering projects. With these projects, we relied on Mahdi to deliver professional engineering, design and drafting services that we could send to our customers for negotiation and approval, and then to our manufacturing team and sub-contractors for manufacture, supply and assembly with fully specified technical models and drawings. Together we have been able to turnaround enquires into jobs faster than we have ever done before. Mahdi has proven to be very professional and trustworthy with any challenge we have put to him. Kohan Services are a great resource and complement the value given with our business services.”
