About Us

Dr. Leslie Andermann

Dr. Leslie Andermann is a Gonzales native and grew up in the Brittany/Burnside area. After graduating from St. Amant High School in 1999, she attended LSU and earned two degrees, in 2003 for her bachelors in Biology, and then again in 2008 with her doctorate from LSU School of Veterinary Medicine. Dr. Andermann has experience in emergency medicine, high volume surgery clinics, and general practice medicine. After living out of state for several years, she came home to Gonzales to open Andermann Animal Clinic in January of 2013. She served as president of the Baton Rouge Area Veterinary Medical Association from 2015 to 2017. Dr. Andermann is very proud to be a part of this wonderful community and she loves getting to build lifelong relationships with her clients and their animals. Her main goal of opening this practice was to bring next-level medicine to the area, combined with compassion and honesty. These days, she spends most of her time doing surgeries and working behind the scenes of the hospital. That being said, she will still manage to pop into an exam room or the lobby just to ask a client “How’ve you been? How’s your family?”, along with giving them a big hug, just to make sure they are ok. Keeping the relationship strong between the clinic and clients is her top priority. Dr. Andermann has worked hard to assemble a great team of doctors to help continue her vision of progressive medicine combined with compassionate care.

When not at work, Dr. Andermann spends time at home with her husband Tommy and their two sons, George and Teddy. Dr. Andermann also has 3 dogs, Toby (a very cranky chihuahua), and Miss Flea and Louis (both Boston Terriers). Being a practice owner and a mom are her two greatest accomplishments, and she is thankful every day for her husband, family, and amazing employees who make it all possible.

Dr. Julie Hackney

Dr. Julie Hackney has been with Andermann Animal Clinic since shortly after the 2016 flood. She was born and raised in New Orleans, and now currently resides in Gonzales. She graduated with her doctorate from the LSU School of Veterinary Medicine in 1998. She has been in practice for more than 20 years and has worked in practices from Monroe to Denham Springs. Outside of her dedication to work, she enjoys spending time with her family, friends, and beloved yellow lab, Dee.

Here at the clinic, Dr. Julie is known for having the best bedside manner, with patient care being her greatest strength. She treats every patient like it’s her own, always going above and beyond to make sure they are comfortable and well taken care of, along with taking the time to properly educate the owner as well. Her bubbly, upbeat, and caring personality makes her a joy to be around. All of these qualities gave her the title of “mom” of the clinic, as she always makes sure everyone is taken care of and keeps things running smoothly.

Dr. Michael Block

Dr. Michael Block is a Louisiana native who was born and raised in Metairie. He earned both his Bachelor of Science and Doctorate in Veterinary Medicine from Louisiana State University.

“Switching veterinarians is always hard especially when you have elderly pets a d those with special needs, so when I decided to switch I wanted to visit the newly opened Andermann Animal Clinic. Dr. Leslie showed me around and made me feel very comfortable to switch to her clinic since it was so close to my home. This summer I had a pet emergency with my Lizzie and Dr. Leslie listened to me during my “freak out” moment of panic and got me and my Lizzie in immediately only to discover she was very sick and needed to go to the pet hospital. She called me everyday to check on my baby, this made me feel so good and just confirmed what I already knew! That I had made the right choice by switching my furry family’s care to the Andermann Animal Clinic. She truly loves what she does and it shows in how she treats her clients with and without fur!!”

~ Denise Fontenot

“Andermann Animal Clinic is the best place to take your furry family members. Dr. Andermann & her staff are caring, friendly, patient, and loving people who’ve made me feel very comfortable when it came to leaving my fur-baby in their care. We love Andermann Animal Clinic!”

~ Tricia Crago & Peanut Butter

“We transferred our fur babies to Andermann Animal Clinic with the hope that our babies would be well taken care of and loved instead of just another animal in need of care. Dr. Andermann and her staff have taken excellent care of our babies from routine shots to the hard decision of having to say goodbye to our sweet Cleo. Thank you for all you have done for us. We will be loyal customers for years to come.”

~ Chris and Allison Dickerson

“My Yorkie is not just a dog she is my child. I trust Andermann Animal Clinic with her life. Very helpful and friendly staff and wouldn’t go anywhere else!”

~ Lori Zeringue

Dr. Andermann always keeps the animal’s best interest in mind while using her expansive veterinary knowledge to solve the problem. Dr. Andermann and her staff have treated myself and my dogs with the utmost respect. Thank you for the wonderful service you give to our community!”
