Dr. TJ Bowe (Bowe Jr.)


I graduated with my bachelor degree in animal science with a minor in business from Texas Tech University in 2013. I went to Texas A&M for vet school and graduated in 2017. After graduation I completed a year long rotating internship at Nashville Veterinary Specialist in Nashville TN. After then internship, I practiced for 1 year at a general practice in Nashville before moving back to work here in July 2019. My interests are in neurology, but I love all aspects of veterinary medicine. This is why I did not choose to specialize after my internship.
I was born while my parents were still in vet school so it was only destined that I follow in their footstep. Now I am literally getting follow in their footsteps everyday. I have basically grown up in this clinic and now getting to be associate and working along side them is amazing. I currently live in Frisco and have one dog who is a black lab/pit mix named Bentley. I pretty enjoy all outdoor activities but really enjoy playing golf any chance I get. My dad and I are just a little competitive against each other.

Rachel is a recent Texas transplant, having moved to the DFW area from Washington in 2019. As she has been interested in the veterinary field from a young age, Rachel was thrilled to learn that NCAC offered hands-on technician training and joined the team in June 2020. She now has two years of hard-earned technician experience under her belt, as well as some training as a surgery technician.

Rachel hopes to continue adding to her knowledge and skill through the valuable experience of the veterinarians and technicians around her, as well as Continuing Education courses. But her BA in English still comes in handy when writing medical notes or supporting the reception team!

Tator Tot was born June 2014 and was quite the sick kitten when he
was brought to us. Not only was he covered in fleas and dehydrated,
but he had a severe respiratory virus and was very weak. After we got
him healthy there was no letting him go, Tator had won our hearts and
Gypsey had a playmate.
Since then, Tator has charmed every client, two legged and four
legged, by simply being himself. You can most often find him in any
unattended purse, an empty box, or purring loudly in a warm place.
Tator Tot, though always busy mingling with clients and patients,
never misses an opportunity to meet his adoring fans and lay in their


Laboratory Technician

Gypsy was born in April 2014 and had a rough start to her now
pampered life. She was brought to us with most of her tail already
missing, and in overall poor condition. Once we had the chance to
care for and bond with her we knew she was meant to stay with us.
Gypsy's current hobbies include drinking fresh water from the faucet,
laying in clean laundry, and hiding in any open cabinet. Though she
rarely makes an appearance up front, she is crucial to our success.
Not only does she insure our lab equipment runs properly, she also
protects us from rolls of paper towels by shredding them to pieces.
