What’s Being Said


“Our family has known Kate for several years through school. Personally, Kate is generous and extremely kind hearted. She’s great with interacting with children and likes establishing relationships with them. Last summer, my son took an art camp with Kate at Treehouse Arts and he was immediately hooked. His love for art is now fostered by Kate, on a weekly basis. She’s extremely flexible and caters to the child’s interests and skill level. She has a multitude of media she uses for instruction that’s very engaging. But she loves what she does…making her an amazing teacher!”

“Kate is a literal magician! She turns the ordinary into the extraordinary. I am never ceased to be amazed by the wonderful pieces my students created in our weekly sessions. While they range in both age and ability, Kate is able to reach them all with her unique teaching strategies and her true gift of connection.. Every week she deftly guides the children through an artistic process. Beginning with a mentor artist and model project, Kate leads step by step. May students are thriving and parents are consistently in awe of the beautifully creative pieces their children bring home. Kate has been partnering with us at North Star Microschool for more than a year. Throughout this time the children have grown in their confidence as artists and also their knowledge of techniques, their interests in art history and skills development. We are so very grateful to have Kate teach each week!”

~Fran Stuart

“Treehouse Arts and Kate are amazing addition to any artist’s life! Once we discovered her, there was no going back. Not only is Kate an incredible artist with years of experience with kids, she is an incredible person as well. Treehouse Arts is a wonderful and safe place to send your child with warm inviting atmosphere that fosters a deep love for art. My kids can’t wait to go back again and again. They have so much fun with Kate while building different art skills and studying in many different mediums and artists. Children and young adults of all ages will find so much challenge and depth here. We are so grateful to have this in our lives”.
