Roger E. Nix, D.V.M.

Dr. Nix is a dog and cat veterinarian originally from southern Indiana. He graduated from Purdue’s School of Veterinary Medicine in 1982 and has been practicing in the Indianapolis area ever since. He specializes in dog pediatrics and geriatrics — his passion for animal health even inspired the creation of JointCharge, a product that helps aging pets live with less joint pain. 

In his free time, Dr. Nix enjoys spending time with his wife and sons. He cares for one dog and a flock of chickens that create a steady supply of fresh eggs at home. His favorite activities outside of the hospital include flying, sailing, and traveling. Alongside his reputation as a trusted pet veterinarian in Carmel, Dr. Nix also owns a practice in Fishers, IN.

Dr. Graves graduated from Purdue University with an animal science degree in 1969. After this, he remained at Purdue and went on to earn his doctorate in veterinary medicine in 1973. He specializes in internal medicine, soft tissue surgery, and practice management. 

A proud member of the American Veterinary Medicine Association, Dr. Graves regularly participates in continuing education programs both locally and nationally. He is also on the Advisory Board of the Vet Tech Institute of Indianapolis.

Upon returning to Indianapolis, Dr. Kacocha became the medical director of Indy Feral, an organization that opposes cruel outdoor cat control policies. At home, she enjoys spending time with her husband Jeff, along with their dog Java and four cats.

Lizzie loves to be outdoors and has a passion for wildlife conservation. At university, she studied coral reef ecosystems in Belize.

Veterinary Assistants

Meet the team: Megan, a red-headed woman wearing blue scrubs works with veterinary lab equipment.


Megan graduated from Penn Foster with her career diploma as a veterinarian assistant in 2012. She has been working in the veterinary health field for the past year and a half. 

Megan has three furry family members — a mixed-breed dog named Buzz, a Beagle named Colby, and a Chihuahua mix named Lyla. They live in Sheridan, IN, with her son Cameron.

Megan is fond of all animals, but she has a special love for pigs. She has described them as “super cute,” with “mellow (for the most part)” personalities. She learned to love pigs during the decade she spent showing them in 4-H, a tradition she carries on today with her son.

Rachel - Pet Groomer at Sherlock Bones Animal Hospital in Carmel, IN


Being raised on a farm fueled Rachel’s love for animals, helping her realize early on that she wanted to work with animals as a career. She spent her childhood riding horses and competing in three-day events while also training dogs for agility and obedience.

Beginning her career in 2009, Rachel learned from some of the best artists in the grooming industry. She competed in her first dog grooming competition in 2018 and won first place with her Brussels-Griffon in the Open Purebred Freestyle event. 

Rachel says the dog grooming competition was a transformative experience and she plans on continuing to compete. Seeing all different types of dogs and cats makes her love for grooming grow with every pet. 

When she sees her clients’ ecstatic reactions to their pets’ haircuts, it brings Rachel great joy. There are endless dog and cat grooming styles, and she’s always eager to please. When she’s not pampering pets, she enjoys caring for her many orchid species and hybrids.
