Mona & Family. I am so sorry for your loss. I have been coming to Greystone for many years. Mark was so kind and gentle. His passion for animals, and his true caring for their well being was persistent. Mark took care of all my Golden Retrievers. The bond they had with Mark was incredible. When he would come into the room, he was literally attacked with love by all of them. He would get down on the floor and roll around with them. I will never forget putting Wilson down, and Mark crying along side of me. He was the true meaning of passion and love for his work. He will be missed.
