Meet the people behind the therapy
Our team combines experienced clinical direction with warm, consistent therapy support. Every child’s program is designed and overseen by a qualified speech pathologist, with trained therapy assistants helping children build skills through focused, engaging practice.
Leah McManus
Speech Pathologist
Leah is a Certified Practising Speech Pathologist with 15 years of experience across clinical, healthcare, education and research roles. She has particular interests in speech sound disorders, literacy difficulties and solving complex communication needs.
Leah’s strength is working out why a child is having difficulty and what needs to happen next. She develops clear, structured therapy plans focused on practical outcomes—such as being understood by others, progressing with reading and writing, participating at school or communicating with independence.
Leah has worked as a university lecturer and clinical educator. This experience shapes the Vibrance model: Leah assesses each child, selects the appropriate therapy approach and designs their program, while trained therapy assistants can provide the frequent, focused practice many children need to progress.
Parents value Leah’s warm, practical and honest approach. She explains complex information clearly, works collaboratively with families and educators, and recommends therapy based on what will make a meaningful difference in the child’s everyday life.
