Cassandra Van Nieuwal, DVM
Veterinary Medicine has always been a part of her life. Dr. Van Nieuwal is following in the footsteps of her grandmother and aunt who have been involved with equine care and veterinary medicine for many years. At age 3 she was already involved caring for animals and knew she wanted to become a veterinarian.
Dr. Van Nieuwal obtained her veterinary degree from Ross University in 2015 including her clinical year at Louisiana State University. While trained in all aspects of veterinary care, her strong interests are in exotic medicine and surgery, as well as endoscopy. In addition to her veterinary training at Ross University School of Veterinary Medicine and Louisiana State University, she also has prior work and teaching experience at Bowling Green State University Herpetarium. Dr. Van Nieuwal is a mom to a plethora of pets including a rescue dog and a long haired cat from the Island of St. Kitts, three other rescue cats, a pitbull, a snake, and a turtle.
Having transplanted from Ohio to Florida, her free time includes running with her dogs, horseback riding, snowboarding, paddle boarding, jet skiing, and spending time with family and friends.

Alyssa Carver, DVM, MS, CCRP
As a former classmate of Dr. Westberry’s, we are thrilled to have Dr. Carver join our team. After completing her veterinary degree at St. Georges University in Grenada, Dr. Carver took a position in western Pennsylvania close to where she grew up, where she’s been practicing for the last two years. With a little coaxing from Dr. Westberry, and the promise of year-round sunshine (plus a few hurricanes), the decision to take the plunge and become a Floridian was not that difficult. Dr. Carver is a Certified Canine Rehabilitation Practitioner, Fear Free Certified, and USDA Accredited. Outside of work, she loves the outdoors, enjoys boating, hanging out with friends, and working out. Her current family consists of two cats that she adopted from Grenada named Tuko and KeeKee.

Veterinary Technicians and Assistants
Stephanie
Hi, I’m Stephanie and I have been in this field since my first job. Since I was in elementary school I wanted to work with animals. As the years passed I realized my passion was dogs. BIG dogs. I currently own 4 Dogues De Bordeaux (aka the “Turner and Hooch” dogs) among French Bulldogs. What can I say- I love the smushed faces! I have had my hand in showing and owned the #6 bitch in the country in 2016. She also placed in the infamous Westminister dog show! Competing in other “sports” with them is also something my husband and I love to do. I breed DDB and French Bulldogs, but my passion outside the show ring, and of course my job, is Neonatal care, birthing and whelping litters of puppies (which usually included cleaning a lot of poop!) Other than that my husband, and our brood enjoy fishing, boating, and spending time with friends out by the fire.

Client Services
Samantha M.
Hi, I’m Samantha; I recently made an exciting career shift navigating from human medicine into veterinary medicine. I was born and raised in a small upstate New York town with two stop lights and 3,000 residents. However, after living in Volusia County for nine years, southern culture has become just as much a part of me as my northern roots. My childhood home was a self-sustaining farm and my time there is what cultivated my deep love and connection with animals and the great outdoors. When not at work I can be found exploring new trails with my furry sidekick, Willow or with my nose buried in a book. I have a real passion for knowledge and look forward to tackling this new adventure in veterinary medicine and the challenges it brings.

Tessa
Hello, I am from Key West Florida, a born and raised Floridian. I have three dogs and two cats that are all rescues. I have been in the veterinary field for almost 10 years. Animals have always been my passion. I have worked in primary veterinarian care, SPCA adoption center, and the Humane Society my whole life. I started in kennels and have worked both as a veterinarian assistant and as a client service representative. I love being in the outdoors, on the ocean, and riding my motorcycle. I also find peace and serenity in being of service to my community and fellow humans. I’m so grateful to be working in emergency veterinary medicine with such amazing like-minded people. I am very lucky to be doing the thing I love the most with people who share my love and passion for animals.

Joan
Hi, I am Joan! I moved to New Smyrna Beach in 2012 and I am finally in the field that I have so wanted to be in since I was a little girl. I am currently studying to become a veterinary assistant. Growing up in rural Florida I got to see and play various animals while horseback riding or walking around. Some of the unusual ‘pets’ that I was able to learn about and release were an armadillo and a mole named Mr. Magoo just to mention a few. While living in Miami for many years I raised and bred cockatiels. I always found strays and strays found me so that I could find their fur-ever home.
