Dr. Gordon graduated from the University of Vermont with a BS in Animal Science in 2001. After four years at the Cummings School of Veterinary Medicine at Tufts, he participated in a one-year small animal internship at the Animal Medical Center in New York.

After four years in a small animal surgery practice outside Washington, DC, he and his family moved to Tasmania where he joined a small animal hospital and was the only specialist (surgical or otherwise) on the entire island.

When not in surgery, Dr. Gordon tries to survive raising three sons. In rare moments of peace, he enjoys finding the perfect recipe, talking about outdoor activities, and subjecting innocent bystanders to his banjo playing.


Hannah Schofield

Practice Manager

Hannah is a British native that emigrated to the US after college in 2003. She entered the veterinary field quite by accident when she took a Saturday job at a small clinic whilst studying for her Masters in Clinical Psychology. After quickly realizing she was pursuing the wrong dream, she shifted gears and started working at a Northern Virginia general practice in 2007. Developing an interest in surgery, she moved into specialty medicine and began studying for her degree in veterinary technology in the evenings. Hannah was staff supervisor for a large surgery group for three years before taking time off to start a family in 2012. She joined Lazar Veterinary Surgery the following year, working from home on her farm in Western Loudoun County that she shares with her horses, dogs, cat, chickens, fish, two beautiful daughters, and long suffering husband. Hannah spends most of her spare time training and competing her retired racehorse, Rigby, in local horse trials, and passing on the horse obsession to her girls.

Kate Ackermann, LVT

Surgery Manager

Kate is a Northern Virginia native who has always had a passion for animals. Over the last 6 ½ years she has learned that veterinary medicine is where she wanted to spend her career and started going to school online to earn her degree in Veterinary Technology while working in a small animal practice. Within the general practice, she learned that surgery was her real area of interest and was thrilled to join the Lazar Veterinary Surgery team in August 2017. After graduating and becoming an LVT, Kate plans to continue taking classes and become certified in surgery and anesthesia. Currently Kate has no pets that live with her but enjoys spending time with all the family dogs and cats, and is looking forward to the day when she can adopt another Dachshand and hopefully one day have a little farm of her own.
