Welcome to

Andermann Animal Clinic!

Our clinic was founded in 2013 by Dr. Leslie Andermann and we are the fastest growing veterinary facility in Ascension parish. We are a small animal general practice located in Gonzales, Louisiana (approximately 30 miles south of Baton Rouge). Our practice scope is limited to companion animals (Dog and Cat). We currently have a rotating staff of 4 veterinarians to handle all of your pets’ medical needs. Along with our wonderful vets, we have large team of support staff that truly love caring for animals. Our practice culture is light-hearted and personable, and our veterinarians are known for their communication and kindness. When a medical issue arises out of our capabilities, we work closely with all local emergency and referral hospitals to ensure your pet receives the highest standard of care. Dr. Andermann, Dr. Hackney, Dr. West, Dr. May, and the entire staff invite you to be a part of the AAC family!

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 behind the scenes of the hospital focusing on administrative duties, managing the hospital, and helping out with overflow cases.  Making sure the clinic runs smoothly and keeping the relationship strong between the clinic and clients are her major areas of focus. Dr. Andermann has worked hard to assemble a great team of doctors to help continue her vision of high quality medicine combined with compassionate care.

When not at work, Dr. Andermann spends time at home with her husband Tommy and their three sons, George, Teddy, and Jack. Dr. Andermann has one very old and sweet Boston Terrier named Miss Flea, and two dogs in heaven (Toby and Louis). 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, but has lived here in Gonzales for the last 20+ years. 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 husband Greg and their four children: Drew, Luke, Hannah, and Sarah.

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 sincere, upbeat, and caring personality makes her a joy to be around. Ask anyone who knows her, and they can attest to how much heart and soul she gives to every one of her patients. It is a true calling for her.  All of these qualities gave her the title of “mom” of the clinic, as she always makes sure everyone is doing well and keeps things running smoothly.

Dr. Jennifer West

Dr. Jennifer West grew up in Louisiana and earned both her Bachelor of Science degree and Doctorate in Veterinary Medicine from Louisiana State University. While still in school, she actually worked for Dr. Andermann as one of her veterinary assistants when the clinic first opened. After getting her veterinary license, Dr. West moved to northeast Georgia and worked in a small animal practice for 3 years, after which she and her husband returned to their home state. We are so honored that she came back to work for us as an associate veterinarian! Her vast clinical knowledge combined with impeccable work ethic have elevated our level of care.  Her calm demeanor and professionalism in every situation have set precedents that we all strive for.  Dr. West enjoys all aspects of veterinary medicine, but she does have particular interest in surgery and dermatology. When not at work, Dr. West enjoys doing DIY projects and being outdoors fishing and hiking with her husband, Drew, her daughter Cecelia, and her dogs, Jax, Mabel, and Isla.

Dr. Mackenzie May

Dr. Mackenzie May was born and raised in Baton Rouge. She completed her undergraduate studies and veterinary school at LSU.  After receiving her Doctorate of Veterinary Medicine in 2020, she joined our team at AAC. Dr. May has had compassion for all animals from a young age, but she became a veterinarian because she loves forming deep connections with people by caring for their pets. Dr. May is known for her perpetual positivity and effervescent disposition, which uplifts the clinic as a whole. Since joining our team, Dr. May has developed an amazing clinical and surgical skill set that has set her far above her veterinary classmates. Her passion for learning and soothing bedside manner make her a wonderful veterinarian. Dr. May’s special interests include dermatology, soft tissue surgery, preventative care, and all things related to doodles! When she is not at the clinic, she enjoys spending time with her husband and their doodle, Crew. Her favorite things include baking, quality family time, and traveling.

She thrives at helping to control the work flow and is a champion at organizing the chaos of a veterinary clinic. She is also one of our best anesthesia technicians and enjoys training staff in the surgery room. She has a great attitude and is always willing to help with any task. In her downtime, she enjoys spending time with her husband and two goldendoodles (Leonard and Bonnie), and traveling.

Her life would not be the same without the company of the Andermann patients. She does whatever necessary to make sure the patients receive the best care possible. One of her favorite parts of the job is monitoring in surgery, which she does on most days that she is at work. She stays on her feet all day, and there’s not a time when she isn’t working hard. Her passion for animals keeps her going.  When Makki is not at work she is caring for her own dogs and cats at home. She also enjoys spending time with her family and being outdoors. The most rewarding thing for Makki is to see that the patients get to return to their loving family pain free and feeling their best.

“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!”
