Among his teachers were Theo Laanen (Residentie Orchestra, The Hague) and John Taber (Residentie Orchestra, New Zealand Symphony Orchestra and Orchestre National Bordeaux Aquitaine). From 1985 till 1990 Theo worked as assistant principal trumpeter with the Haifa Symphony Orchestra in Israel. With the Haifa Brass Quartet he performed also extensively in Israel. After returning to The Netherlands Theo performed with the Radio Symphony Orchestra and many more Dutch orchestras.
