Being an Orthodontist

Few people are fortunate enough to wake up and enjoy going to work every day, but orthodontics allows me to do just that. Being able to continue my father’s footsteps is truly an honor - knowing that I'm now caring for the children and grandchildren of his former patients. I love seeing my patients smile more and more with each visit as their teeth align.  It's great to celebrate with them when their braces are removed and they see their incredible new smile for the first time.

My patients and their families are why I love what I do. They are such amazing people, and I get to know them on a person level throughout treatment. I love their excitement and enthusiasm. It’s emotionally rewarding to be in a profession where I am able to make positive, lasting changes in the lives of people I care about, increasing their self-esteem and the comfort with which they move through the world.

My Education and Commitment to Continuing Education

  • E.D. White Catholic High School
  • Auburn University, Bachelor of Science (Cum Laude)
  • Louisiana State University School of Dentistry, Doctorate of Dental Surgery (D.D.S.) with honors
  • Baylor College of Dentistry, Master of Science in Orthodontics

I understand that orthodontics is a constantly changing field, with developments in materials, processes, and technologies happening at a rapid pace. I also understand that my patients trust me to provide them with the best care available, and I can only continue to do so by staying at the forefront of knowledge in the field. Throughout the year I attend and participate in continuing education offerings at the local, state, and regional levels. I’m also a proud founding member of the Baylor Orthodontics Online Study Club and the Cutting Edge Orthodontics Study Club.

Away from Work

My wife, Toni, and I have two amazing young daughters, Ava and Arden. Our children and family are my top priority, always, and I love the time I spend with them. I’m also an avid triathlete, and enjoy swimming, biking, and running. I’m currently in training Ironman Florida.

Toni and I strongly believe in supporting our community and regularly participate in local events. We also contribute to various organizations, including the Bayou County Children’s Museum, CASA, Femmes Natales, Thibodaux Service League, Bayou Country Club and Crawfish Aquatics swim teams, various athletic clubs, and several school fundraisers and activities.
