Meet Tallulah

Tallulah Breslin, M.S. CCC-SLP (she/they)

Tallulah is a speech language pathologist specialized in gender and identity affirming behavioral voice modification. They founded Harmonic Speech Therapy to help people live their best lives where they're heard and understood. Her passion is in helping people find voices they love. From her very first client here she's been on a mission to find accessible ways to effectively and efficiently modify ones' voice. Given that we all have the same pieces and parts to our voices, they've been able to apply voice techniques to meet diverse client needs. From professionals navigating gender bias in workplaces to yoga teachers wanting voices that can chant with ease all day, they're happy to help you meet your voice goals! Tallulah ensures her services are provided in safe, neurodivergent-affirming spaces for teens and others with voice dysphoria to comfortably explore voice modification. To help others do this work well, they offer workshops to other voice specialists where she teaches one-on-one and in groups how to effectively, efficiently, inclusively, and accessibly teach behavioral voice modification.


Tallulah was born and raised in Austin, Texas. At nineteen, they were caring for a woman who was not able to communicate. Once her client started working with a speech language pathologist she began to communicate for the first time using a speech generating device. This life-changing event inspired Tallulah to become a speech-language pathologist. 

Tallulah received her Bachelor's degree in Communication Disorders from Texas State University, and their Master's Degree in Speech, Language and Hearing Science from Purdue University in 2010.  Tallulah is a Speech-Language Pathologist licensed in the States of Texas and Michigan, and holds the certificate of clinical competence awarded by the American Speech-Language-Hearing Association (ASHA).

Meet Courtney

Courtney Pruitt, M.S. CCC-SLP (she/her)

Courtney has an extensive musical background and has spent most of her life in professional training for voice and piano. She also has training in French horn, guitar, and handbells. In addition to practicing gender affirming voice therapy, Courtney enjoys training her clients in methods of aligning their singing voices with their gender identity.


Originally from small-town west Texas, Courtney decided to pursue speech-language pathology during her senior year of high school. She attended Baylor University for her undergraduate education and then made the move to Dallas to earn her master’s degree in Communication Disorders from the University of Texas at Dallas. She and her husband rushed to Austin as soon as she graduated, where they have always felt at home.


Courtney empowers her clients to find their voice - one that is true to themselves - and allow their uniqueness to shine through.


Courtney is an ASHA certified speech-language pathologist licensed in Texas.


In her free time, you can find Courtney snuggled up on the couch with her rescue, Hank, with a good book in her hands and a record playing in the background.



Fiona began her journey in voice modification in 2020, when she decided to focus on her voice early in her transition. Modifying her voice early on helped her navigate the difficult situations she found herself in during transition. She knows first hand how painful it is when your voice doesn't match you. As a vital part of Harmonic Speech's team, she helps others in similar situations who are in need of guidance and resources. She finds fulfillment in connecting others to the resources they need to complete their transition journey. Fiona is also our expert on health insurance and technically savvy.


Hearing clients when they feeling comfortable with their voice is the reason she loves this work and is committed to our community.

Fiona answers your calls, and is happy to help you with any insurance or technical questions you have related to your appointment.

Meet Madelynne

Kari Meissner, M.S. CCC-SLP (she/her)

I am here to help you develop your voice, safely. My name is Kari Meissner (she/her/hers). As a licensed Speech-Language Pathologist since 2008, I’ve worked with people of all ages and love helping others demystify voice and communication. 

We are used to talking and using our voices all day, but most people don’t know how to change their voice and maintain it safely. My clients become experts on their own voice so they communicate comfortably and confidently every day and without the risks and costs of surgery.


I provide my clients with specialized, individualized, and safe Gender Affirming Voice Modification services. My experiences in support of LGBTQIA+ adolescents, support of parents of trans and Gender Diverse youth, and support of close friends and family who have transitioned fuel my passion to support people in their quest to unlock their ideal voice.​   


I look forward to meeting you!


Madelynne Organa (she/her)
Community Support Specialist


Before voice training, Madelynne's voice being misgendered was a daily frustration. Now that her voice is gendered correctly she feels validated at work, is more confident, experiences gender euphoria, and is just generally more comfortable using her voice. She feels lucky to be able to support our community to help others find a voice that also helps them feel confident.

Madelynne brings her background in film and customer service to help support and build our online community and grow our advocacy efforts. 

We can't wait to hear from you!
