Meet The Team

Dr. Anna Landry grew up in New Orleans and has always loved caring for animals. When her childhood dog became sick and passed away, she grasped the empathy side of medicine and knew she wanted to help owners treat and care for their pets. She graduated from the LSU School of Veterinary Medicine and studied acupuncture at the Chi Institute of Traditional Chinese Medicine. She worked in Metairie as an associate veterinarian for two years before joining the team at the Ark. 

She has two Golden retrievers, Georgia and Loui (short for Louisiana). Georgia is tennis ball obsessed and usually falls asleep with a ball in her mouth. Loui is an 87-pound cuddle bug who loves stuffed animals; his favorite is a 5-foot-long plush penguin he likes to carry around her house. 

In her free time, she enjoys eating at new restaurants with her husband, working out, running, watching movies, and traveling to spend time with friends and family across the country.

Dr. Zachary Carroll was born in Elgin, Illinois and moved to Louisiana in 1996 where he attended St. Catherine of Siena and graduated from Brother Martin High school in 2004. He received a Bachelor of Science degree in Animal, Dairy, and Poultry Science from Louisiana State University in 2008. He earned his DVM at Ross University School of Veterinary Medicine in 2012 and completed his clinical year at Auburn University in 2011.

Following veterinary school, he completed a one-year rotating internship at MedVet New Orleans. Dr. Carroll feels that his internship not only gave him the opportunity to work closely with boarded specialists, but also helped him gain invaluable knowledge and experience.

In 2013, he joined the team at Ark Animal Hospital where his goal has been to provide the best patient care possible. His philosophy is to treat each patient as if it were his own pet. Dr. Carroll’s practice interests include internal medicine, ultrasound, soft tissue surgery, anesthesia/pain management, and oncology.

Outside of the hospital, Dr. Carroll enjoys spending time with his wife Alida, their son Conrad, daughter Blair, and their dog Kitt. You may see Kitt at the clinic—she loves to come play every day! In addition, Dr. Carroll loves to be outdoors, whether it is golfing or attending a music festival.

Dr. Robert Vennen is a valuable member of the Ark Animal Hospital team, bringing extensive expertise in delivering top-notch animal care. With a notable five-year tenure as a veterinarian at Riverlands Animal Hospital in LaPlace, Louisiana, Dr. Vennen's skills seamlessly complement the team.

Although his main veterinary interests are in surgery and preventive medicine, he truly enjoys all aspects of general practice, and he's eager to treat all pets. He continually increases his skill sets and knowledge base in ultrasound, dentistry and surgery through various Continuing Education courses, which he applies to clinical practice. 

One of his best attributes is that he can get along with almost anyone he meets. He has the ability to work well through long days and still maintain a sense of humor, and does not shy away from new challenges that come with providing excellent patient care.

Dr. Vennen's passion for surgical procedures and proactive health measures, especially in orthopedics, has greatly enriched his role at Ark Animal Hospital. 

When he’s not at the hospital, Dr. Vennen enjoys spending time with his wife Lauren, who is also a DVM, and his two beautiful daughters, Addison and Emma.
