My interaction with VNC is ongoing since we have yet to find the cause of my dogs brain lesions. However, I am completely impressed by everyone I've come in contact with at the VNC. Dr Knowles is extremely knowledgeable and took time to thoroughly examine my dog, ask many questions and clarify my multiple questions. He underwent a CSF culture and and MRI and we are still waiting on results. However based on the treatment we've received from Dr. Knowles and the front desk staff I know regardless of what they find, he is in good hands!
