My pathway to Veterinary Medicine started as a very young child, fostered by my supportive parents and siblings as I accumulated various dogs and cats over the years. The world of animals was my haven, and James Herriot my hero.
As a graduate of Oklahoma State University, I believe that being a veterinarian is not limited to just interacting with animals though. I also communicate and incorporate the family into the treatment plan for the pet. My “Gold Standard” is to above all else, do no harm.

I have had the privilege of working at AGAH for my entire career. I have chosen to work strictly in outpatient care as my joy comes from working with the pets and their family. Many of my long-term clients have become my extended family. I have been with them during the good and bad times, both personally and professionally. I thank them for this gift and consider my life well spent on continuing in this manner for years to come.

Currently my daughter is, of course, the center of my universe. She shares with me a love for all of God’s creatures. We share our home with Taggerung, her sleek black male cat who always keeps us both thoroughly entertained.

Dr. Rue has been a part of the Aquia Garrisonville team since 2012. She grew up in a suburb of Melbourne, Australia where she completed a Bachelor of Science Degree with Honors at Monash University.

She has also enjoyed the companionship of several Boxers over the years, and the breed holds a special place in her heart.

Dr. Rue is passionate about science based medicine and loves to educate clients so that they may make informed decisions about the health of their pets. When not caring for patients, she spends her time cooking, gardening and supporting her son’s baseball endeavors. She is also an avid fan of the Nationals.
