Liz Gray, Office Manager
Liz is likely the first person you will talk to when you call. She handles initial scheduling, patient accounts and financial arrangements, and everything to do with keeping the office running smoothly and effectively. She is very knowledgeable about insurance plans, and how to maximize your benefits.
Her trust runs deep: she was a patient before she was the Office Manager!
“I was born and raised in Houston and moved to Huntsville in 1990. After a 23 year career in Banking, I joined Dr. Rathke’s practice in 2000 as Office Manager. I enjoy the challenge of keeping the practice running smoothly, both for Dr. Rathke and our patients.
“My husband, Don, and I live in Huntsville and really enjoy the friendships we have made in our community. We have five children between us, and two beautiful grandsons.
“In my spare time, I enjoy the beach, salt water fishing, gardening, and traveling.”
Betty Brown, R.D.A.
Betty started her career in dentistry in 1969 in Houston. For 22 years, her husband's transfers took her to Massachusetts, Georgia, and Louisiana.
"I was born and raised in Huntsville, and have recently moved back to the area. My life has taken me many places, and I have worked in numerous dental practices.
"Over the years, I have had such great experiences and have learned so much. This led me to Dr. Rathke's office, where I have brought forty years of experience and a willing nature to keep learning and growing.
"I share my life with my husband of 49 years, and we share the love of our two sons and three grandchildren.
"In my spare time, I enjoy fishing and gardening. What a joy it is to be fishing, or to see something grow!"
Rhonda Harris, B.S., A.A.S., R.D.H.
It is with sadness for us and happiness for her that we announce the retirement as of January 2018 of our long-time dental hygienist Rhonda Harris.
In 1990, Rhonda decided on a whim to “check us out” as a possible place to practice, and “I liked it there right away.” Rhonda had to leave the practice several times over the years as her husband’s jobs took them to other cities; but they always returned to Huntsville, and we were always glad to have her back.
And now, after 27 years, the time has come to put her energies into other parts of her life. “I can definitely say,” she told us, “that this is the best place that I ever worked, by far. Working here has been like working with family.”
We will miss her daily presence like we miss family, but Rhonda will be here from time to time as needed when our other hygienists , Kathy Sanders, R.D.H. and Dianne Simmons, R.D.H., need time off .. so we will happily keep her bio here and active!
“I earned my Bachelor of Science degree in Agricultural Economics from Texas A&M University in 1987. I then pursued my Dental Hygiene career by earning an Associate of Applied Sciences degree and my license in Dental Hygiene from Lamar University in Beaumont, Texas in 1989. I have been practicing Dental Hygiene since then, and joined Dr. Rathke’s staff in 1990.
“I enjoy getting to know our patients and providing the best care possible. I also enjoy attending annual continuing education courses with the office staff.
“I have been married to my husband, Tommy, since 1988. We have raised two sons, Ryan and Kyle, who both proudly serve in our United States Air Force. We are active members of the Huntsville First United Methodist Church. During my spare time, I enjoy spending time with my family, traveling, and gardening.”
Rosa E. Cardenas, C.N.A., R.D.A.
"Originally from Chihuahua, Mexico, I arrived in the United
States, my adopted country, in 1987, determined to learn a new culture and
the new language. I married four years later and am the mother of three
wonderful children, and recently, the grandmother of a beautiful baby boy.
"I have spent all of this time working and studying, earning
my GED in 2004, my CNA in 2009, and I studied to become a naturalized citizen in 2007. I believe that education begins at home,
because my parents taught me that goals are obtained, not by dreaming about
them, but by working to achieve them.
"I am a person who lives to serve. I enjoy spending time with
my family, which is very important, and I like to receive friends and cook for them. I have also learned that exercise is vital to be healthy and happy.
"I am grateful for the opportunities presented to me every day!"
"Originaria de Chihuahua, Mexico. Llegue a Estados Unidos de America
la cual adopte como mi patria en 1987, determinada a aprender una nueva
cultura y un nuevo lenguaje; me case 4 años despues y soy la madre
de 3 maravillosos hijos y recientemente abuela de un hermoso nieto varon.
"Todo este tiempo he trabajado y estudiado, obtuve mi diploma de GED en 2004
y mi certificacion de CNA en 2009. Mi educacion no termino alli, despues segui
preparandome para la nacionalizacion norteamericana en 2007; con mi esposo cuidadano de los EUA.
Creo que la educacion fomentada en casa es la mejor bases, pues mis padres
asi me lo enseñaron, eso aprendi de ellos que las metas no se logran solo por
pensar en ellas sino trabajando para obtenerlas.
"Soy una persona que vivo para el servicio al projimo, disfruto mucho pasar mi
tiempo libre con mi familia y amigos,como tambien cocinar para todos ellos.
He aprendido que el ejercicio es vital para vivir saludable y feliz.
"Vivo agradecida por cada oportunidad que se me da cada dia"
