It was one of the most rewarding and humbling experiences of her life.

Dr. Vo has worked as a Pediatric Dentist in Maryland, Old Metairie, and the Westbank, treating children from all walks of life.  Dr. Vo has set her roots in Madisonville where she is raising her family and remains a part of the community.  She focuses a large portion of her practice to the special needs community as it is very important to her personally and professionally.

Dr. Vo enjoys traveling, anything Disney, and spending time with family and friends, her husband Dr. Dominick Alongi, an endodontist (, and her 3 children.  

“I have a passion for children.  That passion has existed within me since I was very young.  I can say that it has brought me so much joy to be able to utilize my passion in pediatric dentistry.   My love for making a dental visit “easier” for those with special healthcare needs and their families is my ultimate goal; and my hopes is to make these visits better than they could have ever imagined!”
