About Us

Studio McCallum's approach to landscape design and the creation of exquisite outdoor spaces is deeply client-centric and client focused. The process of learning a client's needs, wants, ideas and inspirations for a project are the most important part of the design process. Learning these, the creative process for melding those attributes into a holistic plan can begin. The studio translates the vision into reality, giving meaningful input with insights and suggestions as the process develops, so as to deliver a beautiful result that achieves the desired objectives.

Sharing a deep commitment to design excellence and the importance of aesthetically harmonious and pleasing built environments, the partners work closely together to achieve clients' visions for their projects. Cassandra being a Professional Landscape Architect, registered to practice in Montana and Michigan with an extensive design portfolio, provides the creative direction and lead.
