Meet Our Doctors

Dr. Katherine O’Brien

Dr. O’Brien has been a lover and admirer of the beauty and innocent of animals since she was a little girl. Her dreams of becoming a veterinarian in order to help and speak for animals came true when she graduated from Louisiana State University in 2007. She purchased Maricamp Animal Hospital in 2012 with the purpose of creating an environment that always advocated for the animals no matter what the situation. Dr. O’Brien knew the only way to do this and be able to be the saving voice for other animals in the community and statewide was to become a Veterinarian. She saves hundreds of lives every year. Her passions are for the pets of course but also her family. She is married to the wonderful Dr. Alberto Rullan and they have two boys that are learning to love animals as much as their parents. Their household also includes Blue, a Labrador, Henry, a toy fox terrier, Xylazine, a midsize mix breed & too many horses to count.
