"I want to thank her for entering my life and for teaching me so much about design, plants, soil, communication, toughness, boldness, art, and now business. She’s taught me how to be a stronger woman, a leader, and to follow my dreams. I know she will always have my back and I hope one day I can pass along what she’s given to me to another 30- something bright eyed person who walks in the door with big hopes, dreams and a lot of bravery."
