I have worked with Jim for many years (should I say, a few decades) and more recently with Mark, and have always found them to be knowledgeable with regard to all aspects of the materials and properties relating to the dimension stone industry. They are always considered and open with their response.

Gosford Quarries has used the services of Stone Initiatives since the company was first founded and they are always prompt with their estimate of procedures. I recommend them without reservation because of their expertise and service.

Gary Hargreaves, Specification Manager, Gosford Quarries

Working with Stone Initiatives has been a very positive experience – all queries are dealt with professionally and promptly, the quality of the work is 10/10 and the timeliness is spot-on.

The principal, Jim, is one of the most experienced – if not the most experienced – dimension stone experts I have dealt with. Having worked around the world, he is up there at the top. I have no hesitation in recommending Stone Initiatives for any project that is considering stone as a cladding material.

Peter Bouras, Principal, BG&E Facades

Kate consistently went above and beyond to ensure the success of our project, providing expert advice and troubleshooting solutions during some challenging moments. Her professionalism, dedication, and attention to detail stood out, and she made the entire process seamless and stress free.
