I had the pleasure of having Mark Costa as a Uni lecturer in Orchestration, Arranging and Ensemble Performance. He is world class in each of these fields. It’s rare to find someone with such a wide and deep knowledge of all things musical who is also so warm, humble, humorous and personable. Mark was a popular lecturer with our entire cohort, whether a one-on-one Bass Tutor, or with a large Masterclass. Could not recommend lessons with Mark enough. - Reece, Newcastle

I have known to be a remarkable, consistent and professional bass-player and musician, for thirty years. And one of the nicest people you'll find anywhere! - Sam McNally, Sydney

One of the best musicians and teachers in Australia. Highly recommended! - Sue, Sydney

The best of the best, impeccable work ethic, incredible talent, and an absolutely amazing young man. - Kay, Bellingen
