Meet Our Team

We believe our staff to be among the best anywhere and we expect that you will find them very warm and friendly.  We look forward to being of service to you and be a part of your dental health care team.





Noemi  joined  Advanced Microendodontics 2007. Her job is the jack of all trades! Very wise and practical which is essential to our practice. She has been married for 20 years and has 4 children. Two beautiful girls and two 4 legged doggies! Shopping is her favorite pass time (let’s be real whose isn’t :-))! 



Ruth has been in the dental field since 1994 (time to retire :-)). Raised in California but has been in Texas for 14 years (y’all)! She joined Advanced Microendodontics Jan. 2015. She enjoys changing the patient’s perception of having a root canal done with providing TLC and knowledge. In other words chickens and scaredy cats are welcome!! She has been married for 20 years. They have 4 children a boy, a girl and two 4 legged fuzzy kitties. When she DOES retire, she and the hubby are going to travel the US in an RV.



Cori is the baby of the office! She has been in the dental field for 5 years.  Her precious golden retriever keeps her busy.  She likes working out, eating clean and healthy.  Shopping is at the top of her list of favorite thing to do, as well as decorating and music.  






Audrey has been in the dental field since 2009. She started in general dentistry and joined Advanced Microendodontics in October 2016. She enjoys helping patients achieve the ultimate goal, which is to save the teeth they were blessed to receive (you don’t get another set)! She is an avid reader and a retired competitor of multi-disciplined horseback riding. Life today is filled with her husband of over 15 years and the activities of their teenaged son (plus one fuzzy orange tabby). A self-professed chocoholic, she’ll tell you stale marshmallows are tasty too (hey give it a try)!
