  • "For a long time I've wanted to send a note to thank you for your care of our pets. Every time we bring our animals to your clinic, you show the perfect combination of expert care and compassion. I am especially grateful for the sensitivity you showed me when I brought Whitefoot in for the final time. You helped me through a rough time."
