Veterinarians
Dr. Patrick McSweeney
Dr. Patrick McSweeney

Dr. McSweeney grew up in Old Metairie where he attended St. Catherine of Siena School. As a young child he knew he wanted to become a veterinarian. He attended Archbishop Rummell and Vanderbilt Catholic High School when his family moved to Houma.
Dr. McSweeney graduated from LSU Vet school in May of 1984. After graduation he worked at the Louisiana SPCA Hospital where he worked with indigent clients and developed keen surgical and diagnostic skills. For seven years he volunteered his time to do a weekly television segment on WDSU’s morning show which benefitted the Louisiana SPCA and promoted pet adoptions. He continued to volunteer his time for the segment even after he left the SPCA and opened the Animal Medical & Surgical Hospital in 1992.
Over the past thirty years, “Dr. Pat” has focused his practice in the direction of pain management. Trained by Pfizer Animal Health, he has taught pain management seminars locally and throughout the country focusing on anesthesia and analgesia. The Animal Medical and Surgical Hospital has hosted continuing education seminars for local veterinarians regarding this subject. Dr. Pat has also done round table discussions on pain management that included participants nationwide.
Because of his experience with Pfizer (now known as Zoetis), Dr. McSweeney and the hospital have been asked to participate in numerous clinical trials over the last fifteen years. These drug trials require precise data observing and documenting. One of these studies was published in the Journal of Veterinary Medical Association in February of 2012.
When Katrina approached the New Orleans area, the McSweeneys evacuated with their many animals and the hospital’s boarding and hospitalized animals. Dr. McSweeney returned to find his New Orleans home flooded. He borrowed a pirogue and paddled to the second floor of his home in order to recover some belongings. He returned to the hospital only 10 days after the storm with all the animals, along with his wife Beverly and Dr. Carriere and began helping those animals who were left behind. In fact, for months the hospital was basically turned into an animal shelter for those pets left behind who were rescued after the storm.
The hospital also took on another project – helping Lakeview Veterinary Hospital survive the storm. The Animal Medial & Surgical Hospital hosted Lakeview Veterinary Hospital and worked side by side with them for almost a year.
Since then, the McSweeneys have returned to their rebuilt home in Lakeview and Dr. McSweeney has been focusing on disaster preparedness, because in this area, it’s not a matter of if, but when another hurricane or tropical storm will hit. He purchased a motor home for any future evacuations which is parked outside of the hospital.
Patrick and Beverly McSweeney have been happily married since 1984. They have no kids, but have many four-legged children. Dr. Pat loves his pets. He also loves to travel. Although he works hard, he also plays hard. When time allows, he also loves to exercise.
Dr. Carol Carriere
Dr. Carol Carriere

Dr. Carriere was born in the dark ages in New Orleans and grew up in Lakeview, the last of seven children. She graduated from St. Mary’s Dominican High School and went to U.N.O. prior to attending LSU School of Veterinary Medicine, where she and Dr. Pat McSweeney were classmates and became fast friends. Upon graduating from LSU-SVM in 1984, she received the Edward Lloyd Mitchell Memorial Award, as well as the Association of Feline Practitioners Senior Student Award.
Dr. Carriere practiced for five years with Dr. Thomas Rawls at Broadmoor Animal Hospital in New Orleans, then she joined Dr. McSweeney at the LaSPCA for two years. She went on to work with Dr. Lee Capone at Lakeshore Veterinary Hospital in Mandeville and the St. Tammany Humane Society for two years, until finally rejoining Dr. McSweeney at the Animal Medical and Surgical Hospital in 1995.
An excellent surgeon and diagnostician, Dr. Carriere put her veterinary skills and life skills to work after hurricane Katrina when she helped rescue and care for numerous animals injured and left behind. Because her home was flooded and damaged, she lived at the hospital with the McSweeneys caring for animals “round the clock”. Dr. Carriere also used many skills to subcontract and essentially renovate her own home refinishing and relaying floors, installing moldings, cabinets, and painting.
Dr. Carriere is an avid LSU football and baseball fan and has been a devoted Saints fan since their inception. She loves gardening and reading, but her beloved pets have always been the main focus of her life. She considers herself most fortunate in the assortment of animal characters—too numerous to count—she’s had over the years. The most famous of these were Pugsley Carriere, Esq., Attorney at Paw, and his loyal sidekick and co-conspirator, Skeezit. Life during those 16 glorious years with this intrepid duo was wild, but Dr. C. loved it. Though the gang she lives with now is tame by comparison (with a few notable exceptions) Dr. C. still heeds Carmen’s advice: “Watch out!”
“Lots of people talk to animals…. Not very many listen, though…. That’s the problem.”

Beverly McSweeney – Office Manager
Beverly McSweeney – Office Manager

In addition to being our office manager, Beverly is also the wife of Dr. Patrick McSweeney. She attended LSU and UNO and worked as paralegal in the 1980s until she and Dr. McSweeney opened the Animal Medical and Surgical Hospital in 1992. At first the hospital opened with just the two of them, so Beverly was not only the receptionist, but also the veterinary technician and kennel staff. The business grew over the years and has been a part of the lives of many clients, patients, and employees. Beverly and Dr. Pat evacuated for hurricane Katrina with numerous pets and clinic animals. Since their home was severely flooded in the storm, they lived at hospital.
Along with Dr. Carriere, the McSweeneys participated in animal care and rescues after Katrina and housed over a hundred abandoned animals. When people returned to the area, they helped reunite owners with their pets. They also treated pets who needed to be seen as their owners came back to rescue them who had been without food and water for weeks. All of the care was complimentary. After Katrina, the hospital hosted and housed another hospital in our building. Since their building was flooded in the storm, the McSweeneys helped them get back on their feet and save their business. The McSweeneys worked diligently to rebuild and get back to their Lakeview neighborhood and home, becoming fluent in the language of “construction.”
Beverly is very active in her church parish, St. Dominic. A guitarist and vocalist, she directs a music group that plays each Sunday for 10:30 a.m. mass and has done so since 1986. Beverly writes a significant amount of music for the instrumentalists in her group. She was asked to write an article for Oregon Catholic Press regarding her church parish’s recovery from Katrina which was published in 2012. Beverly is kept very busy with all these activities as well as caring for her family’s many personal pets and sanctuary animals. She is also an avid photographer. You may see her swoop in to take a few (or many) pictures of your pet one day.
Mary McSweeney – Bookkeeper
Mary McSweeney – Bookkeeper

Dr. McSweeney’s mother Mary has been bookkeeping for the hospital since the business began in 1992—which is extraordinary because she makes the drive in from Houma weekly to do it!
Married to John McSweeney in 1955, Mary is the mother of a magnificent family that includes eight children, 17 grandchildren, and 13 great-grandchildren! She also is the proud owner of three beautiful Dobermans, Maxie, Lily and Red.
Finally, Mrs. Mary is an amazing cook! She miraculously whips up massive holiday feasts for her large family that are deliciously memorable. We are grateful for all she has done for our hospital since we opened for business. She has been our biggest cheerleader and we love her.

Alexis joined our team in December of 2016. She is a premed student at the University of New Orleans pursuing a career as a psychiatrist. Animals are her absolute favorite things in this world and working at a vet clinic satisfies both her love of animals and her passion for helping those in need.

Three of her foster kitties, Star, Lyra, and Nova, became her first fur children.
