Although if you ask my Mum (mom) I have developed a slight American “twang.” I have been married 17 years to my loving and supportive husband Scott. We have been blessed with two children, Jack and Will. They are the loves of my life. We share our home and hearts with our sensitive Rhodesian Ridgeback Rani and our huge vivacious German Shepherd Blue. The household is led by Inky our rescued cat and we round out our team with our sweet elderly rabbit Midnight.
In my early 20’s, I graduated in Australia with a degree in Finance, spent 3 years working in the financial arena and decided this was not for me. I had always wanted to be a vet and loved Science so thought, why not give it a go. So I decided to quit my job and worked on getting into Vet school until it was a reality and in 1998 was accepted into the Melbourne University School of Veterinary Medicine. I was so excited to go to school and learn and of course loved being with the animals. It was a match made in heaven. I had found my place in life and every day was a great day. I graduated in December of 2001, and moved to the USA two days later, sat board exams and started working in Reno, Nevada, in a small animal hospital. I quickly learned that while I loved being a vet, it needed some “tweaking.”
I wanted to heal the animals and not just send them away with quick fixes. I had been exposed to acupuncture and chiropractic through my horses back in Australia so I understood the concepts and how beneficial it can be for animals to help them find balance. So within 1.5 years of graduating vet school, I started the IVAS course to become a veterinary acupuncturist. I remember sitting in the room on the first day and them saying “your life is about to change.” Boy, they could not have been more right. It opened up my eyes to a whole different way of looking at medicine and healing. So I became a convert. And since then I have thrown myself into holistic medicine with all of my heart. I am grateful to have found a form of medicine that provides true healing rather than masking symptoms.
All of us and our animals have the ability to heal with the right tools. Wellness comes from balance and harmony in the mind and body. It is with true excitement and commitment that I come to work every day. My patients are my teachers and I am grateful for all that they teach me every day.

Gina Stubblefield
Veterinary Assistant
Gina Stubblefield has grown up involved with animals from a young age. When she was 6 she expressed interest in training the family’s Australian Shepherd, and became active in the local 4H dog care and training program. From there her areas of interest expanded into various avenues of animal care.
The Australian Shepherd Club of America had (and still has) a phenomenal junior handler program. The club encourages junior handlers to train and participate in various venues with their dog(s). Since the family had Australian shepherds, Gina was able to work in all fields of training with her own dogs, and eventually picked up handling other people’s dogs as well. The training, opportunities and experiences from showing dogs makes all things dogs second nature to Gina.
She stuck through 4H until aging out, and in her years was active in most of the animal projects. At 13 she won small animal master showmanship at the county and state level. From there on she had the opportunity to start working with large animals. She raised market animals towards the end of her run in 4H, a truly valuable experience, but the dogs were always first and foremost her passion.
At 16, Gina was hired at her local general practice veterinary hospital. She stayed at that practice for 15 years before venturing out with an interest in holistic care.
Currently Gina has three dogs – Abby, a 14 year old Australian shepherd; Jewel, approximately 6 and a half year old husky/treeing Walker coonhound mix; and Rylee (the newest addition), a 1 year old catahoula leopard dog. Gina is an avid hiker with her hounds, not as active in the dog training world at the moment, and she loves exercising her dogs and providing quality care to make each day a perfect dog day!
