About Dr. Brent

Sarah Villani

Office Manager

Being in the dental field for 20 years, Sarah has worn many hats working in different dental office settings.   This has translated in her being one of the most versatile and well-rounded team members at our practice.  She can literally do it all…administrative work, clinical work, and can fix almost anything.  She is extremely passionate about our practice and loves improving lives one smile at a time. When Sarah is not busy at our office, she enjoys spending time with her family and friends, playing softball and volleyball, gardening, crafting (She hand-makes most of our decorations in the office!), learning how to fix just about anything, laughing, going to festivals, and volunteering for area races. She is also the president of her neighborhood civic association and manages the neighborhood pool.

I love going above and beyond to wow parents with our excellent customer service.  I wish all businesses treated people the way we do.– Sarah

Ann Ganucheau

Front Desk, Scheduling Coordinator

Another seasoned veteran on our team, Ann first worked in general dentistry with adults but quickly switched to pediatric dentistry due to her love for helping children.  She is also multi-talented and is able to work the front desk and help out on the clinic floor.  She loves traveling, music, and spending time with her two grown children, her lovely granddaughter, and the rest of her family.

“My favorite part of the day is watching the children that are afraid when they walk in leave smiling and happy after having a great experience at our office.” – Ann

Allison Dempster

Front Desk, Scheduling Coordinator

I have worked in the dental field for over 13 years but recently switched to pediatric dentistry. This is by far my favorite place to be.  I love working with Dr. Burns and our amazing team. I am a mother of two boys.  I enjoy being outdoors and will try to find any reason to be outside on my time off.  I love sports, reading, and dabble in painting every now and then.

I love interacting with all people, no matter the age.  It’s a joy to watch the different personalities of the children in our office.” – Allison

I love working in the friendly environment that each team member works so hard to create. It truly is a mini-family, and I’m so thankful for the opportunity I’ve been given. Not only do I have a great team, but I get to work with kids, which makes my job even better and more fun!” – Madeleine

Asia Dufrene

Dental Assistant

Born and raised in New Orleans, it was Asia’s fiancé Justin (also a dental assistant) who got her interested in the world of dentistry.  After finishing her dental assistant schooling, Asia was able to incorporate her love of children into her career by joining our pediatric dental practice in 2018.  You will find Asia is very friendly, polite, and courteous.  In her spare time, Asia enjoys spending her days watching movies and hanging out with her friends and her wonderful fiancé.  She also enjoys playing with her two dogs…Harry and Philly.   

“I’ve always loved working with kids. My main goal is to make sure each experience your child has at our practice is a great one.” -Asia
