Mom, Parent Guide

 My husband Zack and I have two boys 9 & 7 years old.  Our 9yo was diagnosed with Bilateral Sensorineural (progressive) hearing loss at age four. He is now enrolled in a small public charter school where we work closely with the AI teacher to be sure we are anticipating his needs when possible. 

My dream for him has always been that he have as many options as possible, including communication. When deciding on schools, communication, and future plans, we always try to consider how the decision may limit his future choices. He dreams of being a robotics engineer and attending college as far away as possible.  

I believe every family has a reason for their choices. Our responsibility is to ensure they have access to current information and feel supported in whatever decision they make.

I live in Austin with my husband Steve and 2 daughters, Abby and Emma, who is deaf.  I currently work as a Parent Liaison in the outreach office at the Texas School for the Deaf, also known as the Educational Resource Center on Deafness (ERCOD).

Michaela Hamaker - Texas GBYS Coordinator - Austin, Texas mhamaker.jpg

My name is Michaela Hamaker and I am very excited to begin my journey with Texas Hands & Voices Guide By Your Side as the Program Coordinator! I started in this position in November 2015. I am looking forward to sharing some of my own experiences with other families looking for support in raising their deaf or hard of hearing child.

My husband Kevin and I have three children together, two of whom are profoundly deaf. They both attend the Texas School for the Deaf in Austin. They use ASL as their preferred communication method. 

When I learned of my son’s hearing loss almost 18 years ago, I knew I was about to embark on a journey that was new for our family. There were so many unknowns, and so many questions I had. I began my own research and started looking for ways that would allow my son to be a happy, well-adjusted child who was able to reach his potential. Throughout all of this, the support and guidance of other parents who had already dealt with what we were experiencing at that time was invaluable. When my daughter came along nine years later, we were ready! 

I am delighted that the Guide By Your Side program is set up to provide such support to other parents throughout Texas.
