Noah has been a brass instrument enthusiast since starting the trombone at age 12 and got into serious collecting in high school, under the mentorship of Byron Peebles, when he found his first Bach Mt Vernon 42 and Elkhart Conn 88H trombone and developed obsession of the art of musical instrument craftsmanship. He began working with Steve Ferguson at The Horn Guys Shop in 2001 and helped build that store in the early days, learning a lot about the instrument business along the way and making friends with trombonists from around the world. In 2010, he founded The Brass Ark, his own music store dedicated to the appreciation, collection, restoration and sales of the best new, vintage and used brasswind instruments. It was with this goal in mind, to offer a location where brass enthusiasts could buy, sell, trade and learn about these rare horns and accessories, represented by a seller who is not only an expert and enthusiast himself in the field of vintage brasswinds. He maintains and upkeeps a museum and collection of some of the finest trombones ever made, including many rarities which have become inspiration for new models and equipment brought to market in collaboration with Noah and various makers such as Stephen Shires, Bob Reeves, Markus Leuchter, Brad Close, Stephan Schmidt and others.
