Dr. Laci Le, Au.D
Clinical Audiologist - Texas Locations
Dr. Le sees patients at National Hearing and Balance in San Antonio and Hondo, Texas. She specializes in adult hearing loss, hearing aid technology, and dizziness and balance disorders, and brings experience from private practice, hospital, and Veterans Affairs (VA) clinics. Since joining the team in 2021, she has developed a patient-first approach rooted in evidence-based care and individualized treatment.
Dr. Le earned her Bachelor of Science in Communication Sciences and Disorders, with minors in Pre-Medicine and Psychology, from Southern Illinois University Edwardsville, followed by her Doctorate in Audiology from the University of Illinois Urbana-Champaign.

Her clinical interests include adult audiology, hearing and balance disorders, and comprehensive hearing aid services, including Real Ear Measurements (REM). Dr. Le welcomes both pediatric patients (ages nine and older) and adults for thorough hearing and balance evaluations and hearing aid fittings. She believes that technology alone is never enough — excellent hearing aid outcomes come from patient-centered care, education, and thoughtful, evidence-based fittings.
Outside of the clinic, Dr. Le shares her love of personal growth through her habit-focused blog, where she shares simple, doable steps to build habits that actually stick. She enjoys spending time with her husband and their Great Pyrenees, training for 5K and 10K races, hiking, reading, and exploring new restaurants and bakeries.
