“When working with a client, I listen to what your needs and aspirations are in order to create an environment which reflects your personality and lifestyle.  I use problem solving skills and experience to analyze what will work best to give a client thoughtful, practical, and beautiful design. Knowledge in green design and building allows me to offer you healthier, smarter, more durable, high performance products for the home.”
