Katherine Isaacson, M.S, CCC-SLP (she/her) is a cisgender woman and an ASHA certified Speech Language Pathologist licensed to practice in the states of New Mexico, California, Colorado, and Hawaii.

She is the founder and chairwoman of Gender Voice Center, formerly known as New Mexico Gender Voice Center, a registered 501c3 nonprofit organization, which accepts donations and provides a volunteer team of vocal coaches for folks who are without health insurance, and/or cannot afford the costs of copays, coinsurances, deductibles, or private pay. She is also the founder and owner of Gender Voice SLP, which publishes and provides training content for clients and clinicians. Her first book on gender affirming voice training can be found here.

Kat has a passion for serving the transgender, nonbinary, and gender diverse community and their voice modulation needs. Her highly effective gender affirming voice training curriculum combines Water Resistance Therapy, Confidential Voice Therapy, Straw Phonation, and the Stanley Method to teach resonance placement and control for gender affirming voice clients wishing to create a new sensory motor memory process to change their vocal behaviors. When implemented correctly, her curriculum is safe, gentle, effective, and protective to the vocal folds and vocal tract.

Kat is currently training as a potential Democratic candidate with Emerge New Mexico, as well as earning her doctoral degree in speech-language pathology with MGH Institute of Health Professions, a Harvard Medical School affiliate. She earned her Master of Science in Speech-Language Pathology and her Graduate Certificate in Applied Behavior Analysis at University of New Mexico, and her Bachelor of Arts in English at University of California, Davis. In 2017, Kat was a recipient of the New Mexico Leadership Education in Neurodevelopmental and Other Related Disabilities Fellowship (NM LEND). She completed the New Mexico Partners in Policymaking program the following year, in 2018. She served on the board of the New Mexico Speech-Language Hearing Association (NMSHA) as a Vice President of Convention during 2022, raising the largest amount of convention money in NMSHA's history.
