“Karen is an incredible teacher. I attend ceramics classes in her studio. She works with me on the wheel and hand building with my children. Her studio is well appointed with four wheels and a kiln. We go once a week and LOVE it!”

“The studio at Greentree is perfect - you can spend time learning to throw pottery on the wheels or work on learning hand building techniques. Karen is very talented and generous and allows you to focus on whatever you are interested in. We have been coming for almost a year and the studio is warm and inviting and there is an atmosphere of relaxed fun. I recommend Greentree enthusiastically!”
