Karen Wertenberg Karen Wertenberg is well loved by all of the staff, volunteers, and critters at Sulphur Creek. She seems to have a special connection with the mammals that reside at Sulphur Creek, and she goes the extra mile to take very special care of them. The guinea pigs love her so much that they all start to squeal when they hear her voice! Being a retired teacher, she is amazing with kids and brings incredible life to her programs and presentations in the classroom, at rest homes, and at the Matt Jimenez Community Center. Karen is ready and willing to volunteer for every job that we need her for and always goes into these tasks with 100% effort and enthusiasm. She works well with kids and adults of all ages and is an excellent representative of the District.
