Meet our Team

Originally from New Jersey, Dr. Janell Peterson moved to Tennessee when she started her undergraduate education at the University of Tennessee in 1995. Dr. Peterson fulfilled her goal of becoming a veterinarian when she graduated from the University of Tennessee College of Veterinary Medicine in 2003.

After graduation, she continued her training by completing a year-long internship at Purdue University College of Veterinary Medicine in West Lafayette, Indiana. She moved back to Tennessee in the summer of 2004 and started her job at Powell Animal Hospital, where she was originally mentored by Powell Animal Hospital's founder, Dr. James Sternberg.

She lives in Powell with her husband and twin boys (born in March 2008), enjoying being part of a small community. In her free time, you will find her being a taxi driver for her twins or cheering somewhere on the sidelines of a youth baseball field. She values the time she spends with her extended family, as her parents and her in-laws have all relocated to Tennessee from the Northeast. Serving the pets and people of the Powell community is a tremendous honor, and she is grateful for the trust and support that she has been given throughout her years at Powell Animal Hospital.

Dr. Carr has been practicing in Knoxville since graduating from the University of Tennessee College of Veterinary Medicine in 2001. She grew up in Connecticut and attended Bucknell University, where she received a B.S. in Electrical Engineering. After working in the engineering field for several years, she decided to pursue her interest in veterinary medicine. Dr. Carr likes getting to know her patients and providing care for their individual needs. Dr. Carr enjoys spending time with her husband, two daughters, and their standard poodle. She also enjoys hiking, gardening, traveling, and being outdoors.

Dr. Thom Haig graduated from Purdue University in 1975.  He served five years in the Army Veterinary Corps, most of that time in Germany. He owned a practice in Las Vegas for 10 Years, was a partner in an eight doctor practice in Minden, Nevada, before moving to Knoxville in 2006.

He has been at Powell Animal Hospital since 2008.  His special interests include taking care of the Knox County Sheriff’s dogs and surgery, especially orthopedics.

In his free time, he takes care of the “family zoo.”  Dr. Haig and his wife, Mary Ellen, have dogs, cats, miniature horses, horses, goats, and donkeys. He enjoys traveling to see the grandkids and lure coursing his Pharaoh Hound, Lucy, and whippet, Clark. 

Hello! I have been a licensed Veterinary Technician for ten years, worked in many aspects of vet medicine, including small animal, large animal, exotics, and emergency. After several years of private practice, I began teaching at the Lincoln Memorial University School of Veterinary Medicine and the Veterinary Medical Technology Program. I earned my MBA in the spring of 2018 and am so excited to have joined the PAH team as the practice manager. I love everything about veterinary medicine! At home, I have two cats (Jinx & Jasper), two dogs (Jovie & Juniper), and three horses (Flash, Olaf, & Molly) to keep me busy!

Kristen is a Knoxville native and has been in the veterinary field since 2012. She graduated from Cedar Valley College with her Veterinary Technician degree and plans to continue that education with a specialty degree later on down the road. She has 2 dogs and a husband at home: Chloe the pit bull, Sadie the boxer, and Brandon the husband. They keep her hands full!

My name is Meredith Hayden and I’m originally from Little Rock, Arkansas! I attended the University of Arkansas for my undergraduate career and majored in Animal science. I moved to Knoxville in August of 2019 to begin my studies at the University of Tennessee College of Veterinary Medicine. I’ve worked with animals at different clinics and rescues for the last decade now and I’ve loved every minute of it! I was trained to be a jack of all trades so you might see me at the front desk, working with our doctors, or taking care of your fur babies that are boarding with us! 

As of right now, I plan on focusing on small animals after completion of my DVM. I’m partial to dogs with short legs and elderly kitties. I have three babies: Beale (3 year old Golden Retriever), Gumbo (1 year old Dachshund), and Sia (4 year old DSH). I would love to have more (especially a ferret or an iguana) but my husband is at his max. 

I love working at Powell Animal Hospital when I’m not in class because it’s such a great opportunity to get hands on experience! I may never leave! 

Ariel is Fear free certified and cat-friendly certified. She is currently at Lincoln Memorial University in their CVM program, learning to become a veterinarian. 

Hello! My name is Keana, and I am currently a student at Lincoln Memorial University studying Pre-Veterinary Medicine on the Veterinary Health Science pathway. I have been a part of the PAH team since January 2019, and I hope to one day become a doctor of veterinary medicine. I have two dogs, an English bulldog named Tee Bone and a French bulldog named Hercules.

Hi! My name is Lexie and I was born and raised here in Powell, Tennessee. My love for animals stemmed from getting my first fur baby when I was 7 years old, Minnie! She is a Maine Coon and she just turned 15! I have 2 other Maine Coons, Tiki and Lou. I graduated from Powell High School and I am completing my Associate’s Degree at Pellissippi State currently. I will be attending Ashworth College to pursue my degree in Veterinary Technician. I am also a theme park enthusiast, especially for Disney World! My family and I love to travel there as much as we can. I look forward to meeting your fur babies as I continue my career here at Powell Animal Hospital!

Hi! My name is Amy Worsham. I’m a native Knoxvillian and have been in the Powell Community for over 25 years! One of the most precious gifts to me is the unconditional love we get from our pets. ❤️
