Dr. Jason Randall, DVM

Thanks to a successful 30-year career in veterinary medicine, Dr. Jay has a plethora of touching stories. His favorites, however, involve meeting young families who raise their children with pets. He loves watching the families create unique bonds that stay with them for life; much like the wonderful memories he has for his first dog, Rags. When Rags was diagnosed with diabetes, Dr. Jay remembers how a compassionate doctor helped add years to the dog’s life, allowing him to remain an important part of the family. Through that process, Dr. Jay decided to be a veterinarian. 

After graduating from the University of Illinois in 1983, he gained extensive surgical experience at the Animal Emergency Center of Lake County, where he focused on trauma surgery and wound management. Since opening the Animal Hospital of Woodstock in 1991, Dr. Jay has pursued specialty interests in ultrasound, completing a five-year commitment to advanced ultrasound training, endoscopic diagnostic procedures and laser surgery, for which he has acted as a national laser surgery consultant. 

Outside the office, Dr. Jay enjoys spending time with his family, writing and pursuing outdoor sports such as hunting, hiking, camping and fly-fishing. He also remains an active member in the community by participating in his church and the Woodstock Rotary Club.

 Dr. Spencer White, DVM

Dr. Spencer White grew up in the small farming community of Taylorville, IL. Helping out on his grandparents' farm, he was instilled with the importance of taking care of animals and the significance of the relationship we share with them. His grandparents' early lessons influenced and encouraged him to seek out a career in veterinary medicine.

He attended the University of Illinois for both undergraduate and veterinary school. During this time at the College of Veterinary Medicine, Dr. Spencer served as the class representative for the class of 2014 and president of Omega Tau Sigma, the professional veterinary fraternity focusing on philanthropic efforts throughout the Champaign-Urbana community. He graduated in May of 2014.

Dr. Spencer is very excited to be part of such a wonderful team! His special interest is reproduction.

During his free time, Dr. Spencer pursues a very wide range of interests. Camping, hiking, fishing, ice fishing, Frisbee golf and most outdoor activities are a the top of his list. When not engaged in these outside activities, he enjoys reading, writing, acting, watching movies and spending time with his close friends and family. Most of all, Dr. Spencer enjoys spending his time with his dog Freckles.

Dr. Lindsay Andsager, DVM

Dr. Lindsay grew up in Naperville, IL. She decided that she wanted to be a veterinarian in third grade, when her uncle (also a veterinarian) invited her family to visit the University of Illinois Veterinary School Open House. Touring the vet school,  she envisioned working with animals as a career and never changed her mind! Her passion for animals began as a little girl, playing with stuffed animals and begging her parents for a variety of pets. In high school and college, Dr. Lindsay was fortunate to go on numerous mission trips with her church, where she learned of her deep love for helping people in need. Veterinary medicine is the perfect way for Dr. Lindsay to combine her passion for helping both people and animals. 

Dr. Lindsay attended Yale University for her undergraduate studies and the University of Illinois for her doctorate in veterinary medicine. At Yale, she majored in biology and was a varsity athlete competing on the Yale gymnastics team. After graduating with high honors from veterinary school, she practiced one year in Downers Grove, IL before joining the Animal Hospital of Woodstock. Her areas of special interest include oncology, internal medicine, and surgery. 

When Dr. Lindsay isn’t working, she enjoys working out, traveling to visit family and friends, and spending time with her pets. She has a collie dog, Berkeley, a ragdoll cat, Miel, and a beta fish, Petey.

Dr. Stephanie Willney, DVM MPH

 Dr. Steph was born and raised in Illinois. She attended Carroll University in Wisconsin for undergrad and the University of Illinois Urbana-Champaign for veterinary school. While attending veterinary school, Dr. Steph also completed her Master's in Public Health at the University of Illinois Chicago. Dr. Steph uses both her degrees to serve the Woodstock community but also globally as she volunteers with Christian Veterinary Missions Fellowship. This allows her to travel, learn new cultures and help empower others by caring for their animals. 

Dr. Steph has traveled to Haiti, India and Indonesia teaching classes on caring for livestock and performing spay, neuter and deworming clinics in rural areas where there are no veterinarians.  In her free time, Dr. Steph enjoys spending time with her husband renovating their home and attending family game nights. She also is an avid reader, loves watching movies and tending to her family's ever growing zoo.

Read What Our Clients Say

  • "I cannot stress how awesome the entire staff is at Animal Hospital of Woodstock. We are new patients of this office and I’ve been going through random drama with my cat and his food allergies. Any time I call with a “crisis” the staff is warm and understanding all while being prompt with advice or instructions. If you are looking for a new vet I highly recommend this office. Thanks to Dr. Chris for taking such good care and concern with Watkins!"

  • "Thank you for your evening hours! We ran into a problem with our dog at 6:30 PM (he had something caught in his throat) and we were able to run over to our regular Vet clinic and get care. Dr. Chris was great and a big help! He even checked up on us the next morning. We've been clients for a long time, and really appreciate all of you!!"
