Dr. Christine Barnhorst took over ownership of Walker Valley Veterinary Hospital Nutrition & Wellness Center in December of 2019 from Dr. Kate Lucas who founded the hospital in 2002. Dr. Barnhorst has chosen to remain a privately owned hospital in the sea of ever expanding corporate owned hospitals. By doing this we have the freedom to practice medicine with the best interest in mind for you and your pet. 

We have expanded our services to include vaccine titers, full-service dentistry including digital dental x-rays, soft tissue surgery, abdominal ultrasound, hospitalization of sick patients, in-hospital immediate lab results, acupuncture, cold laser therapy, nutrition consults, exotic animal medicine and surgery as well as echocardiograms/cardiology consults done by Dr. Petrie, a board certified cardiologist.

After graduating from Notre Dame and Purdue University College of Veterinary Medicine over 29 years ago, Dr. Barnhorst started her career as a veterinary Captain in the US Army where she trained enlisted soldiers, performed public health duties, cared for military working dogs and pets of military families. She then began practicing as a small animal veterinarian throughout NY and NJ. Dr. Barnhorst is skilled in small animal medicine, surgery, dentistry, acupuncture and nutrition. 

We are pleased to announce that Dr. Stephanie Chlebowski recently joined our hospital as a full-time associate. She is one of the kindest, most compassionate and intelligent veterinarian you will ever meet. She is skilled in small animal medicine, surgery, dentistry and has a special interest in exotic animal medicine and surgery. 

We are an integrative full service veterinary hospital putting an emphasis on wellness and nutrition. We are seeing a lot more cancer, arthritis, allergies and other inflammatory diseases in both our pets and ourselves. We hope that by becoming more aware of what causes these diseases you may be able to make some changes that will improve the quality of the health of your pets. We value every client and patient that walks through our doors and strive to make every interaction as enjoyable as possible.

We invite you to help yourself to a non-GMO, organic beverage and snack while you relax in our waiting room with a wide screen television on our comfortable couch and chairs. We hope that you will become part of our family and stop in to visit whenever you are in the neighborhood!
