Emi Preston, MS, CCC-SLP 

Speech-Language Pathologist


Emi is a devotional creature. She has lived on Big Island since November 2021 and has fallen in love with the community, beauty, and rawness of the island.

Emi was born in California and moved with her family all around the mainland growing up. Her cats and younger sister were her constant companions during these times of transition. She speaks fluent Spanish and conversational Japanese and Mandarin.

Emi received her Masters in Speech-Language Pathology (CoreSLP Program) from the University of Washington in 2019. She worked as an SLP at an elementary school in Washington for two years, where she specialized in bilingual/multicultural assessment and treatment. During her graduate training and time in the schools, she gained experience evaluating and treating developmental delay as part of an interdisciplinary team. She feels grateful to bring this experience to Wala’au Therapy. It is a great honor to support the growth of our keiki, and to deepen in connection with families.

Outside the clinic, you can find Emi training and performing contortion (ask about upcoming shows!), immersing in the ocean, reading, writing, preparing nourishing meals, basking in sunshine, and talking story.
