Our Staff

Nassim Diaz, BC-HIS

Board Certified Hearing Instrument Specialist

I am a licensed hearing instrument specialist, and I joined the Newsound family in February 2016. I have cared for patients as young as eight years old all the way up to the age of 101! I especially love working with senior citizens and take great pride in the level of care and support that is provided to each person. Seeing a patient flourish brings me great joy in my professional life. Though not a native Texan, I have lived in Houston since the age of two and obtained my bachelor’s degree at the University of Houston, where I graduated with honors. I love to spend my free time with my husband and daughters (identical twin girls) and my 2 dogs! My family and faith are my most valuable assets.

Katrina Gutierrez

Patient Services Coordinator

I’m Katrina, but please call me Kat. I am a southern-born country girl that has been in Houston almost two years now. I am a single mother to three amazingly beautiful girls. I am a sports junkie, love anything outside, love to cook and am fascinated with psychology. I am intrigued with how the brain works and how we respond to those functions. I live every single day with a passion as if it were my last day. I love to talk and interact with people and have always known that’s what I am meant for.

I was hired on with NewSound in July of 2015. I love the psychology behind helping others appropriately, and I never knew what I was missing until I came to NewSound. I began not knowing anything about the industry or what it takes to save a hearing life. Throughout the last 19 months, I have learned what it takes to truly set a standard for patient care. I love being able to give my patients back a portion of their independence and watch them gain back their confidence. I take transforming lives seriously and portray that every single day I walk through the door.

Wife, Billie, received the most understandable brief ever of her hearing problems to assist us in making a decision on where we go from here. Have another appointment to decide on her future with which hearing aids she will need.
