Mary Ann Collins
Licensed Veterinary Technician
A lifelong Westchester County resident, Mary Ann attended SUNY Farmingdale as an “aggie” and planned on going into dairy farming. However, after she realized that cows were a 24/7 job, she turned her focus to small animals and exotics as a veterinary technician. After running a boarding kennel in Harrison, NY, Mary Ann returned to the veterinary technology world and worked in several small animal hospitals around Westchester and Connecticut where she gained invaluable experience working with birds and other exotic species. She lives in South Salem with her dog and two birds. When she’s not caring for all the needy wildlife that comes to her door, Mary Ann is at the Veterinary Center caring for all the exotic pets and helping us keep the hospital on track.
Licensed Veterinary Technician
Originally from Saginaw, MI, Sarah earned an Associates of Applied Sciences in Veterinary Technology from Baker College of Flint, MI in 2011. She then worked for 5 years in a small animal private practice where she realized how exciting working with birds and exotic pets can be. As a result, Sarah joined the Veterinary Center to pursue her interest in exotic animal medicine. When she isn’t in the exam room questioning clients about their pets, Sarah can be found behind the scenes in the surgical suite prepping patients for surgery – one of Sarah’s passions. At home, Sarah lives with two rabbits and one rat and loves to watch movies, play video games, go camping and travel.
With her unique interests, such as barrel racing horses and collecting sneakers, Jasmine is truly one-of-a-kind. Originally from Queens, Jasmine has lived in Mount Kisco for over 20 years and has owned all types of exotic pets, from African gray parrots to hamsters to leopard geckos. She decided in high school that animals were her calling, so she began working in veterinary hospitals as a teenager. No matter how busy she gets answering phones, typing on the computer, or speaking to clients, Jasmine has a smile on her face. She is the ultimate multitasker whose goal it is to educate every pet owner who comes to the Veterinary Center about preventative care for their invaluable animals.
Always a lover of exotic pets, Angie grew up with chinchillas, rabbits, and turtles of her own. Thus, she was a natural fit for working at the Veterinary Center. With her big smile and quiet demeanor, Angie greets all of the Center’s clients with a big hello on Saturday mornings. Although she is a terrific receptionist, Angie hopes someday to go to veterinary school, herself, and is gaining invaluable experience working at the Veterinary Center. If you stop by the Center on the weekend, be sure to give say hi to Angie, and tell her all about your special exotic pet.
Originally from Mount Kisco, NY, Zenia has had a passion for animals since she was born. She has cared for more pets (over 200!) in her life – including chinchillas, snakes, turtles and pigeons - so far than most people do in a lifetime. Zenia first came to the Veterinary Center as a high school volunteer, and we loved her so much that she has stayed on with us as a veterinary assistant. Whether restocking our supplies, helping the veterinarians, or lending at hand at the front desk, Zenia is always busy. Now that she has completed high school, Zenia is hoping to gain experience by working at the Veterinary Center so that she can go on to apply to veterinary school.
