Katherine Isaacson, M.S., CCC-SLP

Katherine (Kat) Isaacson, M.S, CCC-SLP (she/her) is an ASHA-certified speech-language pathologist and cisgender woman who has spent years thinking deeply about how people change their voices, and developing a different way of thinking about that process.

Through her clinical work, books, research, and online content, Kat has helped people explore and develop voices that feel more authentic, comfortable, and uniquely their own. Her work has given her a broad perspective on the ways voice, communication, identity, and self-expression intersect, and on how deeply personal the process of voice change can be.

Her approach is grounded in a simple idea: voice work should be shaped by the individual, not by assumptions about how a person should sound. Her curriculum helps people understand what is possible, give them the tools to explore it, and let them decide where they want to go with it.

She believes people deserve thoughtful, accessible information about how their voices work and how they can change them, as well as the freedom to decide for themselves what they want their voices to do.

Her goal is not to prescribe a particular voice, but to give people the knowledge and tools to explore what is possible, and make informed choices about what feels right for them.
