I have known Stephen for 7 years when I moved over to Yamaha CSG clarinets. This was the first time in my professional life I felt that I could call at any time with technical issues and have it sorted without fuss and always immediately. His knowledge and care over each issue no matter how big or small was such a joy and I felt confident with his expert handling of my instruments. It is with thanks and gratitude that I had the courage to switch over to a completely new way of playing with the CSG and I haven’t looked back since. In my view Stephen is one of a kind and totally reliable and professional. I owe him a lot!
