I was lucky to have Cath as my registrar, during my early years as a consultant ... she was the sort of brilliant trainee that made me be better! Thereafter, it's been so cool to witness her amazing rise to becoming an excellent academic and expert rhinologist ... and I love that Cath nowadays via her lectures and demonstrations continues to make me be better!
