Sonia Ponce


Treatment coordinator/ Financial coordinator

When you come into our office, I am usually at the front desk scheduling your next appointment.  I really enjoy talking with each of our patients and their families. I am a registered dental assistant with certifications in Hospital Administration and Medical Records. I was born in Dallas, TX, and have been living in Little Elm since 2003. It is great to work near my home and with my neighbors. I have been married for over 20 years and am blessed with four children. When I’m not working, I enjoy going to the movies, to local sporting events and to church with my family. At Rendon Orthodontics, our patients enjoy a family atmosphere and we have the privilege of getting to know each family and giving them personalized care. I have been working at Rendon Orthodontics for several years now and as I have gotten to know the Doctors the thing I most admire about them is their dedication to our patients. They definitely go the extra mile!


Earnestine Williams

Scheduling Coordinator

 Being raised in south Mississippi, I moved to North Texas in the summer of 2014. While I've enjoyed working in General Dentistry for the past 12 years, I'm excited to have crossed over to the "Ortho" world.  I have a 13-year-old daughter and I love to bake. When I'm not handling patient care, I'm in the kitchen with my daughter making custom cakes and treats. The Rendon team has welcomed me with open arms. The doctors are super sweet and genuine to me. I know the patients will see and feel the same. I look forward to greeting you at your next visit at Rendon Orthodontics.  


Ana Velasquez


Head Orthodontic Assistant

I was born in Dallas, Texas, and have been in the orthodontic field since 2003. I began working as a receptionist and became certified as a chairside orthodontic assistant soon after. Ever since, it has been a great experience learning so much about how to achieve beautiful smiles. I love working with children and adults and enjoy the rewarding experience of seeing their whole lives change during the time we see them. I have two amazing children with whom I love spending quality time. My favorite hobbies are to play sports and watch movies with my friends and family. Also, I absolutely love to sing! It's been an awesome experience to work at Rendon Orthodontics. The doctors are very professional and treat their patients very kindly.


Kimberly Rodriguez

Orthodontic Assistant

I am originally from Sunny, Florida and now live in Frisco with my fiancé and son.  I have been in the orthodontic field for over 20 years as an assistant.  I am blessed to have found such a fulfilling area of expertise to be a part of. When I’m not treating patients and helping them create their beautiful smile, I enjoy keeping busy with my family doing outdoor activities and crafts.  The Rendon family has made me feel very welcome, as I know they will you.    


Gladys Guerrero

Orthodontic Assistant

I am originally from Monterrey, Mexico and have been in the orthodontic field since 2000.  After taking a few years off from work to be a full time mom to my twin boys and daughter, I decided to be back.  I am very blessed to be part again of the Rendon Orthodontic team.  They are professional and are committed to giving each patient the smile of their lives.  When I'm not helping patients create their beautiful smile, I love spending time with my family and pets.  I also love creating party decorations and doing many other crafts.

Oscar Crespo

Orthodontic Assistant

I have always been interested in dentistry and I started my career working as a Dental LabTech in 2011 in Venezuela. After I mastered working in the lab, I felt ready to discover and increase my professional skills. I moved to the USA in 2014 in order to learn the language.  I decided to study a new area of dentistry.  During my first 2 years, I worked as an assistant in general dentistry and then I decided to combine my professional skills and jump to the orthodontic field.  I am so happy because I can watch my patient’s smiles transform and also utilize my lab tech skills in order to make appliances for them. In my free time, I enjoy discovering areas of this country, and relaxing with my friends and family.


Ellen Schandlbauer


Marketing Coordinator

In May 2012, I became Rendon Orthodontics' professional relations coordinator. I love marketing our practice both internally and externally to dentists in the community. My job takes me to many dental offices and allows me to interact with lots of interesting people. On the days I am working in our practice, I am blessed to be in the company of amazing coworkers. The staff at Rendon Orthodontics is kind, professional and completely dedicated to their patients. I am the proud mother of two children and am happily married to my wonderful husband of 13 years. When I am not working, I enjoy spending time with my family. My dream day would be exploring the wonders of nature with my loved ones in a Spanish-speaking country!
