At the time of your initial consultation, you will sit down with Dr. Theunissen to discuss your plastic surgery goals in detail. Once all of your questions and concerns are answered, Dr. Theunissen will discuss the best surgical techniques to achieve your desired results.

Breast Reconstruction - A.L., Facebook & Google Review

“I was referred to Dr. Theunissen by my oncologist Dr. Bowie. This was not a surgery I wanted to do but needed to do, and I had a lot of anxiety. He really eased my mind by answering all my questions. I trusted Dr. Theunissen & his staff to take care of everything, and I’m glad I did! I could not be more happy & healthier now!! :-))”

“I travel from Alexandria to Baton Rouge to see Dr. T, even for minor treatments such as Botox and/or fillers. In treating me, Dr. T has set the bar so high, I don’t even inquire about local doctors anymore. They just won’t measure up. Oh, I’m sure we have good doctors here, but Dr. T is great! You can trust Dr. T. He listens to your concerns and goes out of his way to see that you are happy. He instantly puts even the shyest person at ease. Let me not neglect to mention Dr. T’s phenomenal staff! He has the best nurse and reception area 🙂 Thank you, Dr T & Staff 🙂 Blessings, Lydia Cortello”

“My experience with Dr. Theunissen and his staff was exceptional. I had consulted with other groups for my procedure, but decided to travel outside of Lafayette based on his professionalism and attention. His follow-up made me feel that he truly cared about me and my outcome.”

L.J., DIEP Breast Reconstruction, Facebook Review

“Dr. Theunissen is absolutely a brilliant surgeon! After complications with breast implants from previous double mastectomy and reconstruction performed by well-known surgeon in New Orleans, Dr. T spent several visits with me explaining Diep Flap procedure. I really did not want to have this surgery; however, it was my best option. I’m so thankful for Dr. Theunissen and his highly experienced staff! My results are fabulous! I smile every day when I think of what a challenge I was and how happy I am today! Oh, by the way, he discovered a small kidney cancer, which was evident on first CT scan at beginning of my cancer journey! He arranged for partial removal of kidney with a fabulous urologist in Baton Rouge. He absolutely saved my life. Dr. Theunissen did his job, God heals!!!”
