Dr. Alongi was also recognized for clinical and research excellence with numerous awards and distinctions including the Ponti Award for clinical Excellence in his endodontic residency. During this time, Dr. Alongi also spent time at the National Institutes of Health (NIH) in Bethesda, Maryland as lead investigator evaluating the regeneration potential of stem cells from inflamed human dental pulps. He successfully defended his thesis, and went on to receive his certification in Endodontics as well as a Postdoctoral Master of Science degree in Oral Biology.


In addition to operating in private endodontic practices in Northshore and Metairie, Louisiana, Dr. Alongi maintains active membership in numerous professional associations. He stays up to date with the most current concepts of the practice of endodontics, with particular emphasis on endodontic microsurgery and implantology. He also has unique experiences in pediatrics with a focus on regeneration concepts. His emphasis on patient comfort, as well as keeping up-to-date with the latest advancements in Endodontic techniques, enable him to provide you with the best quality of care in the field.

Dr. Alongi lives in Madisonville, Louisiana with his wife Dr. Katherine Vo, a pediatric dentist,, and amazing children. During his spare time, Dr. Alongi enjoys spending time with family and friends, traveling, water sports, and fishing.

I am proud to provide my patients with the best in dental technology, treatment options and patient comfort. It is my pleasure to address all your endodontic questions and concerns.
