Dr. Nix, originally from Southern Indiana, graduated from Purdue’s School of Veterinary Medicine in 1982 and has been practicing in the Indianapolis area ever since. His clinical interests include canine pediatrics and geriatrics, and his passion for animal joint health inspired the creation of a company to manufacture JointCharge, an all-natural Hyaluronic Acid-based joint supplement that he and other veterinarians use to treat age-related joint issues in dogs and cats.

In his free time, Dr. Nix enjoys spending time with his wife and sons. Their family also includes one dog and a flock of chickens devoted to creating a steady supply of fresh eggs. He counts flying, sailing, and traveling as his favorite activities interests outside of the hospital. In addition to his reputation as a trusted Carmel Veterinarian, Dr. Nix also owns a practice in Fishers, IN.

Practice Manager



I have been in veterinary medicine for the past 30 years, 20 years of it working in busy emergency practice and running the ICU department. I have been married to my best friend for 3 years. We have two children, Ashley, a stay at home mom to our two grandsons, and Nick, who is a professional pilot. We love to be outdoors, hiking, biking, camping, kayaking, fishing and sitting by a fire with our grandsons. Life is good.

Veterinary Assistants


Megan McKinney

Megan finished at Penn Foster with her career diploma as a veterinarian assistant in 2012 and she’s been working in the veterinary health field for the past year and a half. She has three furry family members— a mixed breed dog named Buzz, Colby a Beagle and Lyla a Chihuahua mix. She lives in Sheridan with son Cameron.

Megan loves all animals but especially pigs, describing them as “super cute” with “mellow (for the most part)” personalities. Her affection for pigs grew throughout the decade she spent showing them in 4H, a tradition that carries on today with her son.


Karlee started her career in veterinary medicine as a junior in high school
for a large and small animal practice. She continued working at a veterinary clinic while attending college where she received a degree in criminal justice. She quickly realized the veterinary field was her calling. She resides in Sheridan with her six fur babies, Doberman mix (Dobie), two Chihuahuas (Nugget & Gypsy), a chiweenie (Sassy), a cocker spaniel mix (Norman), and a tabby cat (Davidson). In her spare time she enjoys couponing, spending time outside, naps, riding motorcycles and spending time with her Gran.




For over 15 years Allison has been involved in animal rescue in one form or another. It was roughly 5 years ago that she decided to grab her passion for dogs and cats and become a professional dog groomer. She graduated from Animal Arts Academy in Carmel Indiana at the top of her class and has not looked back. “I love what I do and look forward to going to work every morning.”

Allison specializes in working with puppies and shy/uncertain dogs. She takes her time with them and strives to make every dog feel comfortable and loved. “One of the greatest joys of my life is to be able to take a scared dog with an uncertain past and make his grooming a completely paws-itive experience!”



I'm the new Groomer at Sherlock Bones. I have been a groomer for 15 years. I have a deep passion for connecting with each pup or cat I groom. I don't have a certain breed that I like more than others, I truly enjoy them all. I'm always trying to learn and grow as a Groomer. I look forward to making new connections.
