Please call us at 609-286-2080 to speak to one of our caring veterinary staff members!

Dr. Katina Carter


Originally from North Jersey, I worked as a veterinary receptionist and then technician up there for four years before deciding to return to college to pursue my lifelong dream of becoming a veterinarian. While working full time, I began my pre-veterinary studies at Rutgers University in New Brunswick. I attended there for 3 years before achieving early acceptance into Oklahoma State University to finish my veterinary training. While studying for my DVM at OSU, I met my husband by way of my surgery partner who didn’t want me driving home alone during our first winter break. Knowing that Bill was also from New Jersey, she asked him if he would caravan with me. The rest of THAT story is history, as the saying goes!

After we graduated in 2006, we came back to New Jersey and I started my veterinary career in Bill’s parents’ practice in Hamilton. In 2007, I began working in this area before opening Animal Care of New Egypt in 2013. By 2016 our practice had expanded greatly and in 2018 we opened Heartland Veterinary & Boarding in our current building. Opening this practice has given us a true sense of “homecoming” as many members of our staff, including myself, worked for the previous practice that occupied this location.

Over the 12+ years that I have been practicing, I have been able to focus on several aspects of pet care that I find both challenging and very rewarding. I have taken a special interest in veterinary dermatology in order to help many pet owners manage their pets’ skin conditions/diseases. I am also certified to practice “Fear Free” medicine, an initiative started by Dr. Marty Becker, which enables us to alleviate some of the stress of veterinary visits for both pets and their owners. When I am able to sneak in a little down time, I enjoy reading, scrapbooking, and riding quads with my husband and daughter, Alivia. She tells us she wants to follow in our footsteps so she can often be found here, “helping out”. The three of us share our home with a pit bull mix, a husky mix, a German shorthair pointer, 4 cats, a bearded dragon, a guinea pig, 3 hermit crabs, numerous chickens, 2 ducks, a cockatiel and a male betta fish named Arielle.

Dr. Bill Carter


I am a third generation veterinarian originally from Hamilton NJ. I graduated Magna Cum Laude with a BS in biology from Delaware Valley University in 2002. In 2006, I graduated Summa Cum Laude with my DVM from Oklahoma State College of Veterinary Medicine. I am a member of the Veterinary Honors society Phi Zeta. My first year of practice was spent at Red Bank Veterinary Hospital in Tinton Falls, NJ. The next nine years I practiced at my family’s clinic in Hamilton, working with the Hamilton Township Animal Shelter, and multiple rescues. I have always had an affinity for surgery and perform all of our surgeries here at Heartland. Outside of work I enjoy spending time with my wife Katina and daughter Alivia, as well as caring for our reptiles, chickens, ducks, and furry family members. On the weekends you will find me tinkering in the garage, hiking, camping, or riding dirtbikes.

Dr. Kiley Mabin

Associate Veterinarian

I am from Bordentown, NJ and have been a part of the Heartland family since 2015. I began working as a veterinary nurse at the former Animal Care of New Egypt while in college. I graduated with my Bachelor of Science in Biology from Stockton University in 2018. My interest in furthering my career in veterinary medicine then led me to Oklahoma, where I earned my Doctorate of Veterinary Medicine from Oklahoma State University in 2023 (go Pokes!). During my fourth year of veterinary school, I completed a clinical rotation at Heartland and soon returned as a doctor after graduation! My interests include geriatric medicine, behavior, and fear free medicine. In my spare time, I enjoy spending time with family and friends, soaking up sun at the beach, and anything Disney!
I look forward to meeting you and your furry family members and welcoming you to our Heartland family.

Nancy Napoleon

Practice/Kennel Manager and Receptionist

I have been in the veterinary field for almost 20 years, predominately as a receptionist but have, on occasion, helped as a veterinary nurse. When Animal Care of New Egypt opened, I took on the role as practice manager and since we moved and became Heartland Veterinary & Boarding, I have now added kennel manager to my many hats! I have lived in this area for most of my life and graduated from Northern Burlington High School (many moons ago!). I am ruled by my 4 dogs, Buford, Daisy, Puddles and Bubba and live to serve my 2 cats, Miss Kitty and Captain Jack Sparrow. I love what I do and look forward to seeing you and your furry family members here at Heartland.

Christine Keefe


I am originally from Queens, NY but have lived in New Jersey for the past 18 years. I have always had a love for animals and would bring home every puppy or kitten I found. I attended New York School of Dog Grooming and later started working as a veterinary technician and fell in love with the veterinary field. In my spare time I enjoy being with my family and attending dog shows with my Norwegian buhunds. My fur family includes my buhunds Iya and Hugo, my miniature poodle Wylie, and my 3 kitties – Sock, Revan and Chrome.

Judy Witt


I have been involved with rescue for close to 20 years. My passion for animals goes back to childhood. My pets have included a parakeet, fish, dogs, hamsters and more recently, cats. I advocate for pet adoption; especially seniors, FIV+ and special needs, spay/neuter and owner education. I have been a vet assistant at a high volume spay/neuter clinic, help out at community wellness, vaccine and spay/neuter clinics in underserved communities and at my local shelter. Interacting with patients and clients is a rewarding experience. My two senior cats keep me busy at home along with daily sharing for pets needing homes.

Susan Kemler-Sibree


I retired after many years of employment as a case manager for high school students with special needs.  Working as a receptionist here at Heartland Veterinary and Boarding provides me the opportunity to continue helping people, as well as  follow my childhood dream of caring for animals.  Outside of work I enjoy spending time with my husband, Bill, my daughters Megan and Kelly, as well as my two rescue cats, Jasper Newkat and Fiona Mae. I have a special interest in adopting older cats.  I am also involved in sea turtle research and protection activities as a volunteer with the Barbados Sea Turtle Project through the University of the West Indies.

Marisa Mastroianni


For as long as I can remember, there has always been a pet in my life. I love caring for and working with animals. In 2011 I graduated from the Veterinary Assistant Program at Mercer County Community College so I could pursue my passion in this field. In my spare time I enjoy going to the beach, reading and spending time with my dog, Sophie.

Danielle Eckert


I developed a great love and compassion for all animals at an early age. I began working in the field back in 2001 as a kennel assistant. Since then, I have worked as a veterinary nurse and now as a veterinary receptionist. I have had many animals throughout the years but it was my pit bull that stole my heart! I credit him for me being the avid supporter of the pittie world that I am today. They know just how to brighten my smile! When I’m not at work, I can be found enjoying the outdoors with my photography or going to the beach, farmer’s markets and animal events where I can meet new fur friends.

Rebecca Mufalli

Senior Veterinary Nurse

I have always had a lifelong love of animals. As a little girl, I always rescued anything in need! Many years later my love is still strong and I have lots of animals of my own. When not at work, I can usually be found playing with my animals or outdoors wheeling, riding, building race cars and mud trucks, or sitting by the bonfire!

Kiley Mabin

Veterinary Nurse

I earned my Bachelor of Science in Biology from Stockton University and plan on becoming a small animal veterinarian. While attending Stockton I worked as a veterinary nurse at Animal Care of New Egypt, which gave me the opportunity to meet wonderful clients and their pets over the years. After graduation and once we moved to Heartland Veterinary and Boarding, I was promoted to senior veterinary nurse. In my spare time I enjoy reading, cooking, watching movies, and going to the beach with family and friends. I look forward to welcoming you and your fur baby into our new Heartland family!

Chelsey Wood

Veterinary Nurse

I was born and raised in New Egypt and graduated from New Egypt High School in 2008 before beginning the hunt for what I wanted to do with my life. Working in the restaurant business was only supposed to be temporary but after 5+ years, it was more than enough time to move on and pursue my passion of working with animals. I completed 1 year of online schooling through Animal Behavior College, completed 200 hours at an internship in Hamilton, NJ and I have now been working as a Technician for 2 years! I love all animals but pitbulls tug at my heartstrings! I have 3 at home. My boy Blue, my precious princess Royce & the sweetest puppy girl Rayne! They are just as much my children as my daughter is.

Alison Gatto

Veterinary Nurse

I’ve always had a deep love for all animals and that has never changed. Growing up I knew I wanted to work with animals and after graduating from Mercer County Community College in 2019, I set foot on my journey to a career in veterinary medicine. When I’m not at Heartland helping care for your adorable fur babies, you can find me at home spending time with my own! My current pets include 2 cats, 2 gerbils, and a pitbull mix named Charlotte who’s a total ham. My other hobbies and interests include camping, reading, cooking, hanging with friends, playing music with my dad (including guitar, bass, drums and piano) and much more!

Amy Guigno

Veterinary Nurse

I have always surrounded myself with animals! As a child, I received my Girl Scout Gold Award by giving information seminars on proper pet care and collecting over 400lbs of pet food donations for the SPCA. As soon as I was old enough I volunteered with the Monmouth County SPCA and the Fort Monmouth Veterinary Clinic. Prior to coming to Heartland I worked for over 7 years as an emergency/critical care technician and have done some work with exotic pets. I am currently owned by 5 cats and lots of chickens and spend my free time working towards creating a fully sustainable farm.

Victoria Dollard

Veterinary Nurse

Animals have always been a big part of my life. I grew up on a farm in Pennsylvania and spent my time caring for cows, horses, pigs and chickens. It’s been many years since then and I still spend most of my time caring for various animals. When I moved to New Jersey a few years ago, I decided to make a career out of my love for animals and am currently in school to further my knowledge of animal care. When not at work I’m either spending time with my dog, cat, chickens, and turkey or exploring the woods on my ATVs, fishing and hiking.

Andrew Reres

Project Manager/Technician

I am a full time one on one aide at a secondary school in Hamilton, NJ and have been a veterinary technician for several years. In addition to my technician and kennel experience, my knowledge of computers have helped me become the go-to technology expert at Heartland! My hobbies include riding four wheelers, karate, photography, fishing, and riding my motorcycle. I always look forward to spending time with my pup Quorra and spoiling the “Kit-ten” who rules my household!


Patient liaison

I have been with Heartland Veterinary & Boarding since early 2014. I have made it my job to be involved in anything that goes on here. While checking in for your appointment, I will perform a preliminary exam which includes an evaluation of your pet’s tolerance for cats, client lap test, and handbag inspection. During the doctor’s exam, I may play “peek-a-boo paw” under the door to distract a nervous patient. When your appointment is over, I will meet you on the front counter to assist you with check writing, receipt signing, and future appointment scheduling as I sprawl across the calendar. In my spare time, I enjoy sunning myself on the front window sill and hiding my toys under the scale.


Clinic Inventory

I have been here since mid 2014 after staging a “sit in” in front of Dr. Carter’s car one night. My duties are slightly more behind the scenes than my feline colleague. Most days I can be found clearing the top shelves in the pharmacy or hiding in the food closet sampling for quality control. My hobbies include keeping Dr. Carter’s chair warm and napping in my Kitty Kube.



I joined the team in 2016. My main job here is towel warming for hospitalized and surgical patients but I’ve also recently taken on the task of post op observation. I have found that peeking in on patients in the recovery ward has been a helpful distraction to nervous patients who are waking from surgery or waiting for their rides. When you can’t be there, I will! When I’m not on duty I like to spend my time eating.
