Certified Academic Language Therapist

Deborah Brown


Deborah is specially trained in the multi-sensory approach which uses the five (5) senses to unlock a student’s ability to read, write, and spell with confidence.


This strategy engages students by making learning fun and helping them to understand the spelling of words. It also focuses on the instructional details behind reading a passage, and/or the mechanics of writing.

Deborah founded Hill Country Dyslexia Services in 2019. Her professional career as an educator began in 2003. She has taught in public school as a classroom teacher and as a dyslexia specialist. Deborah has been previously in public schools and a private school as dyslexia specialist/CALT for a total of 17 years. Although she retired from the public school system in 2019, she continues her passion of helping and instructing children with reading difficulties such as dyslexia and related disorders.

As an experienced educator, she recognizes the challenges that people with dyslexia face in both academic and personal settings. Due to this, she is dedicated to providing an individualized, evidence-based curriculum for her students so that they are equipped with the knowledge and tools to not only be successful in school, but in life as well. The children that Brown has seen throughout the years are so important to her. She stays in touch with former students and their families after they are finished with therapy.

Deborah holds a master’s degree in Education from Texas State University. Furthermore, she is a Licensed Dyslexia Therapist (TX # 2129), and a Certified Academic Language Therapist (TX # 4385). She is a certified Wilson Reading Systems Dyslexia Practitioner as well. 


Her goal is to provide all her students with a foundation of Orton-Gillingham based reading instruction.  Therapy used can be either Basic Language Skills or Wilson Program. Each curriculum is a  multi-sensory approach to improve their phonemic awareness, decoding,  fluency, cursive, spelling, vocabulary, comprehension, and written language skills.  She hopes that every single one of her students will continue to grow, improve, and become their own biggest advocate!

Dyslexia Specialist

Marcia Harlan

Marcia has close to forty years in the field of educating young students.  She earned her degree in elementary education at Texas Wesleyan University in Ft. Worth, Texas.  She is a certified professional who has dedicated her life to ensuring that students achieve and learn the love of reading.


Prior to serving as a dyslexia specialist at Travis Elementary School, San Marcos, for nineteen years, Marcia taught in the Kindergarten through Fourth Grade classrooms.  Throughout those eighteen years, she became acutely aware and sensitive to the struggling readers in her classroom, which began her journey of discovering why they were having difficulty.  More importantly, her deep interest led her to the reality that these struggling readers actually did have the potential to learn and flourish.  Her desire to acquire all the skills she could to facilitate their success led her to the Neuhaus Education Learning Center in Houston, where she studied over the course of five years, totaling over 200 hours of training in Multisensory Reading instruction.  Following her training, for three summers, she facilitated long distance learning from Neuhaus for teachers in Language Enrichment training. 


As a dyslexia specialist, she mentored teachers as they were acquiring the skills of teaching reading, taught students in first through fifth grades daily, served as a Response to Intervention committee lead, and served on the districts’ Dyslexia placement committee for nineteen years.


 As rewarding as these responsibilities were, her greatest passion has always been to work with the struggling reader, especially those that have been found to have dyslexic characteristics and other learning difficulties.  Teaching them to “break the code” of the complex English language, giving them the love of a variety of different language forms, playing with word meanings and learning to spell, continues to be what Marcia is most passionate about.

Marcia is also a member of the:
