Andrea Keller is a licensed architect with 25 years of experience in multifamily, residential and boutique hotel design. Her work seeks to bring people into greater alignment with their core values, their communities and the earth.

A key component of Andrea’s work lies in the life-long study of sacred geometry, symbols and pattern language. Andrea uses unique geometry and proportion systems for each project, bringing power and resonance to the design. As we know from epigenetics, our environment can literally change our genes – her mission is to use architecture for healing, activation, and amplification of personal power. She is currently designing healing centers worldwide.

She was a professor of Architecture at both USC School of Architecture and Otis College of Art + Design. She holds degrees from the University of Pennsylvania (B.A., Design of the Environment) and UCLA (M.Arch), and studied Sustainability through Gaia Education. She lectures regularly for the Institute of Classical Art + Architecture.

Shannon Lee Harris is the founder of Homeself, a pioneering approach that blends neuroscience, interior design, and self-development to transform the way people experience their spaces and themselves. With over a decade of experience in real estate development and custom interior design, Shannon has led projects ranging from full-scale renovations to finely tailored finish packages, guiding clients to create environments that are as functional and resilient as they are beautiful.

In addition to her design practice, Shannon is a certified yoga teacher and holds a Neuroscience Coaching certificate, bringing a rare integration of somatic awareness, brain-based coaching, and spatial intelligence into her work. She helps clients recognize how their environments directly influence their nervous systems, moods, and behaviors — and how subtle, intentional shifts can unlock hidden parts of themselves.

Shannon’s genius lies in being a bridge between science, energy, and self-evolution. She doesn’t just design spaces — she decodes the subconscious language of the home, revealing how textures, light, rhythm, and flow can sustain well-being and call forward new expressions of self. Her work has become a love letter to wholeness, guiding people to create environments that honor every part of who they are and who they are becoming.

Through Homeself, Shannon empowers individuals, families, and communities to rewire their spaces and rewire their minds — aligning inner and outer worlds to foster resilience, clarity, and transformation.
