Absolutely the best. Dr. Lewis has been taking care of all of our animals for many years, and provides the best possible health care for all our dogs and our cat. When she moved her practice from Columbia to WInnsboro, we did not hesitate to make the drive. Besides, the drive to her office in Winnsboro from NE Columbia takes less time than driving to downtown Columbia, & is easier because there are no traffic problems. Dr. Lewis diagnosed & directed medical interventions that saved our labrador retriever's life on two separate occassions, but perhaps just as importantly, she focus on advising us on how we can keep each of our pets in optimal health throughout their lives. She has helped us with allergies, infections, spinal stenosis, arthritis, spaying, accidents, and more! Her rates are very fair, & her focus on keeping them healthy saves $$ while keeping our pets happy & comfortable. Dr. Lewis is a great vet. Both she & her staff care about their patients & their families.
