Patrick McSweeney

Dr. Patrick 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 Vandebilt Catholic High School when his family moved to Houma.

Dr. Pat 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. McSweeney 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 & 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 JAVMA (Journal of Veterinary Medical Association) in February of 2012. The article can be found in the Article section of this website.

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 story regarding the recovery of the two hospitals is included as a link in this website. 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 rebuilding the hospital and finding a new normal. 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.

Carol Carriere

Dr. Carol 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 5 years with Dr. Thomas Rawls at Broadmoor Animal Hospital in New Orleans, then she joined Dr. McSweeney at the LaSPCA for 2 years. She then worked with Dr. Lee Capone at Lakeshore Veterinary Hospital in Mandeville and the St. Tammany Humane Society for 2 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, etc.

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 first and foremost, her beloved pets have always been the main focus of her life. Indeed, most of her time is devoted to fulfilling the importunate demands of her numerous pets. This she does not mind, as she considers herself most fortunate in the assortment of characters, too numerous to count, which she has possessed over the years. The most famous of these characters 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), at home, 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

Beverly McSweeney is the Office Manager of the Animal Medical & Surgical Hospital and is 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 after the storm. 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. They became 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 spends her spare time caring for her family and her many pets who keep her VERY BUSY . 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

Our bookkeeper is Mary McSweeney, mother of Dr. Patrick McSweeney. She has been bookkeeping for the hospital since the business began in 1992. This is extraordinary because she makes the drive in from Houma once a week to do this. Married to John McSweeney in 1955, Mary is the mother of EIGHT, grandmother of SEVENTEEN, and great grandmother of THIRTEEN – what a magnificent family! 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.

“Nature teaches beasts to know their friends.”

Ashley and her fiancé, Robert, took incredible care of Denali as she declined. We are so proud of everything they did for her. Denali was “the favorite” dog of our hospital. She was like our resident dog as we saw her and spent time with her almost every day for the past six years. We are all still recovering from losing this wonderful friend and think of her every day.
