Dr. Kelleen Madill is originally from Port Orange, FL. She completed her undergraduate studies at the University of FL obtaining her degree in animal sciences and a minor in zoology. She went on to complete her veterinary degree at Western University of Health Sciences located in CA. She is currently finishing a Master’s degree in Public Health at the University of South FL. She lives with her husband, Rob, her sons, Ethan and Colin, and their 3 pets, Stubbie, Sophie and Nelson, the cat.

In her free time, she enjoys reading, going to the beach, running, and spending time with her family. Her favorite time of the year is football season where she undyingly roots for the Green Bay Packers and the Florida Gators!

Dr. Chelsea Larkin is on our team of awesome veterinarians at North Bay Animal Hospital. She received her Bachelor of Science in Biology with a Business minor from the University of Florida (Go Gators!) and she received her DVM from LSU School of Veterinary Medicine (Geaux Tigers!)

Dr. Larkin became a veterinarian because she has always loved and respected animals and as she grew older, she became interested in the sciences, specifically medicine. She was lucky enough to find a career that intersected two of her passions which led her to where she is today.

She shares her home with Nitro, a rescue dog from the Bahamas who she got as her 16th birthday present and Cannoli, a special-needs, previously feral kitten from the streets of Baton Rouge. Both her dog and cat mean the world to her. She could have a no good, very rotten day, but when she comes home to her dog greeting her and her cat chirping and rubbing against her leg, everything that happened before crossing the threshold of her house disappears!

Dr. Larkin’s goal walking into every visit is to make sure both the patient’s, and the client’s concerns are heard and addressed. She also wants to emphasize client education so owners can be informed, active participants in the healthcare of their fur babies.

Her philosophy that she lives by is:

“The more you know, the more you know you don’t know.” Aristotle

When Dr. Larkin isn’t caring for your pets, you can find her cycling, fishing, playing guitar, and looking for shark teeth at the beach.

She is from Jupiter, Florida and new to the area so she is always looking for food recs and if you ever see her out and about, don’t be afraid to stop and say “hi!”.

I am originally from Tampa, Florida and I am so happy to be back in the area. I attended the University of Florida for my undergraduate studies where I earned my Bachelor’s degree in Animal Sciences. I continued my education at the University of Florida and earned my Doctorate in Veterinary Medicine in May of 2024.

I have been drawn to animals my whole life. My love and respect for animals stemmed from my childhood where I spent most of my time competitively showing and riding my horse, Buckley.

I am engaged to my fiancé Sam. We currently do not have any animals in our home but are excited to add a canine addition in the future! I recently lost my Great Dane in March 2024 and he meant the world to my family and I. It is a special bond that is indescribable.

My goal walking into every visit is to make the clients and patients feel as comfortable as possible and for them to know I am there to help in every way I can to provide the best outcome for the animal.

My philosophy: You can’t stop the waves, but you can learn to surf.

Outside of veterinary medicine, I love to exercise, cook, travel, attend concerts and outdoor markets, and spend time with family and friends.

I look forward to meeting you and taking care of your pets!

I earned my Bachelor’s in Biology, Pre-Veterinary at University of Central Florida (2019) and my Doctorate of Veterinary Medicine (DVM) at St. George’s University.

I have always had a passion for science, the medical field, and animals. It has been my dream since I was a little kid to make a difference and save all creatures big and small. Getting to work with animals every day truly fills my heart.

I have an Australian Cattle Dog named Mushroom. My dog means everything to me. He has been my best companion through all of life’s challenges, including my journey through veterinary school. I can only hope to give him half the love he has given me.

My goal is to build strong relationships with my clients and their loved ones while providing the best care possible. I am dedicated to continually educating and advocating for pet welfare, and I strive to grow every day to enhance the care I provide. Every day is an opportunity to be a great day!

When I am not at the hospital, I like to hike with my dog, scuba dive, and cook! I love spending time outdoors and visiting farmer’s markets!
