Dr. Bill Marcello

Following in the occupational footsteps of his father, C.J. ”Doc” Marcello, Dr. William Marcello attended Louisiana State University School of Veterinary Medicine. He started his own practice in Mathews in February 1982. One month later, he opened a second clinic on LA Hwy 39, otherwise known as Grand Caillou Road, in Houma. After his son, Dr. Blake Marcello, became a licensed veterinarian, they decided to close the Grand Caillou location and build a new, large, practice on the west side of Houma in 2010. Dr. William has served the Lafourche and Terrebonne parishes for more than 40 years and is excited to see patients in his hometown of Thibodaux.

    Rita Couch

  • “The staff here is incredible! I called with an emergency for my baby and was immediately given an appointment. When I arrived, they took us straight to the back and examined her right away. The doctor explained everything that needed to be done and worked quickly. After the procedure was finished, I was called to pick her up. The service was exceptional, and the price was surprisingly affordable! I expected it to be expensive and was shocked at the total. I’m definitely switching to this clinic for future care. It’s rare to find such amazing care at such an affordable price! "

  • “The office is very nice, and the staff very friendly and professional. Dr. Marcello is very knowledgeable and was great with my dog. He is not my regular vet but only because the drive is a little far, but I might switch anyway soon. Highly recommend! "
