Danielle Barnewolt, Receptionist

Danielle is from Illinois and has recently relocated to Tucson for higher education. She has been in the veterinary field since 2013. Danielle has been passionate about animals since she was a child. She has 2 loving dogs at home. Danielle has volunteered at several animal shelters in the past alongside working in the field. She has always been interested in furthering her involvement and education in veterinary medicine. She previously worked at an animal ER while living in Illinois. She gained years of experience and knowledge from the clinic due to the vast differences in each animal and diagnosis. Danielle is specifically interested in big cats and yearns to help rehabilitate those in need. It is her life long goal to open a big cat sanctuary where she can help them live the life they deserve. While there are many years and obstacles to go, she is hopeful she will accomplish her dream of saving neglected and abandoned big cats.

Loree Kester, Receptionist

Loree was born and raised in Cottonwood, AZ. She moved down to Tucson in 2015 to work towards a career in the veterinary industry. Loree started 4H/FFA in middle school and began raising market sheep, even beginning to breed market lambs for other local students and found herself with her first horse. These programs also gave her an abundance of leadership skills and introduced her to many crucial people in her life. She discovered at a young age her passion for animal care and working in a clinic, especially when learning from her aunt, a CVT of nearly 30 years. With her Queensland Heeler and love of her life, PJ, right at her side, Loree is thrilled to join the family here at Greenway Pet Clinic. Loree hopes to continue to grow in her knowledge of the veterinary world and learn as much as she can.

Darren Gardner, Veterinary Technician

Levi the cat

Levi (AKA Leviticus), is our resident clinic cat. He is 9 years old and came to us when he was just a year old. Levi loves to chew on anything plastic, which landed him an outside cat at his previous owner’s because he kept chewing his owner’s insulin pump line at night. Once outside, he was likely hit by a car and came to us with a broken leg. We repaired his fractured right front leg, and he became a resident at the clinic from that point on, as outside life was not for him. Most time you willfind him sleeping on the copy machine, or his cat tree by the doctor’s desk. When the mood strikes him, he will often wander into exam rooms during appointments.

Dear Greenway Pet Clinic Clients:

The global spread of COVID-19 is a concern for everyone. I wanted to let you know that Greenway Pet Clinic has also taken some preventative measures to ensure everyone’s safety, clients and employees alike.

We are continuing to do curbside service only, with the exception of end of life appointments. We appreciate peoples understanding about not entering the clinic. It is for everyone’s safety to keep a distance and not be confined in a small space. We also ask that clients wear masks when interacting with the staff. We wear masks continually inside so we can provide care to your pets and not spread the virus between each other.

I ask that if you are sick, stay home and do not bring your pet in. Please find someone else to bring your pet in if he or she needs to be seen. I want to try to accommodate all our patients but won’t be able to do that if my staff and I get sick.

In addition to daily temperature checks upon starting a shift and wearing a mask, any staff member who starts to feel sick will be sent home and asked to go get tested. If they do have the Coronavirus, they will have to stay home a minimum of ten days or 24 hours past resolution of signs if longer than ten days.

I am not sure when this curbside protocol will end. Unfortunately, this pandemic is far from being under control. I am looking forward to the day when the infection rate is under control and we can again have some sense of normalcy.

Please be safe and take care, Carole Treat DVM
