Principal, founder, and project architect, Mark has over thirty years of experience in providing design excellence in creating beautiful, client-driven, sustainable places and spaces. Growing up in Wisconsin, with Frank Lloyd Wright 'nature-inspired' buildings around him, it was natural for Mark to get one of the first dual degrees offered in Architecture and Environmental Design. Taking advantage of our amazing views, abundant sunlight and fresh, mountain air, Mark strives to save energy on each project while keeping us all healthier and happier. In the future, Mark believes that as a society, we will better attune our built environment to accommodate day/night temperature swings, saving energy and taking advantage of clean power while happily re-connecting us to the surrounding nature.
