Sandy was born in Gettysburg and presently lives at Hundredfold Farm, the first cohousing community in Pennsylvania. See www.hundredfoldfarm.org for more information about the community.

Sandy received her Masters degree in Education from Shippensburg University. Her goal is to help people of all ages overcome learning challenges by developing underlying processing skills, such as processing speed, and executive function skills. Specific tools and techniques are matched to the specific learning issues to address the root causes of a learning disability.

Students of The Learning Curves find that they spend less time on homework. They report that they are able to pay better attention and are more successful in the classroom. The number one comment heard is that students feel more confident in their abilities to do their work independently.

Services are provided in South Central Pennsylvania, not far from the Maryland border. The Learning Curves is located eight miles west of Gettysburg, PA, (near Cashtown, PA), or from Maryland, just north of Emmitsburg.
