Mike Greenfield
Mike created Greenfield Geotechnical to take the advanced aspects of engineering and computer science and apply them to modern geotechnical practice.
With his background in soil mechanics and foundation design, Mike strives to develop robust, efficient, and economical geotechnical engineering solutions.
Melani Banks
Melani Banks joined Greenfield Geotechnical in 2021 with over 10 years of experience in geotechnical consulting. As a Project Engineer, she focuses on traditional geotechnical engineering projects, particularly the design and construction of multi-family housing facilities. Engineering naturally combines her concern for the community and environment with her love of math and science and flair for bureaucratic detail.
Tim Estep
Though he has a background in law, Mr. Estep’s interest in the environment and outdoor recreation generated a strong curiosity in mapping and geospatial information. Since 2021, he has focused on the collection, analysis, and visual presentation of geologic and hydrologic data in support of the engineering solutions developed at Greenfield Geotechnical.
He collects data, processes geospatial layers, manages GIS databases and ultimately develops intuitive and visually compelling maps and figures to complement the recommendations, reports, and publications of Greenfield Geotechnical’s engineers. He also provides business support and technical editing of the firm’s written work product.
Christina Sanon
Christina Sanon is a civil engineer working at the intersection of seismic risk and data-driven decision-making. With experience in both structural design and geotechnical earthquake research, she has mapped earthquake hazards, assessed vulnerable structures, and applied data science to support informed planning.
Her work spans liquefaction mapping, remote sensing analysis, and post-disaster reconnaissance. Across these efforts, Christina is committed to translating complex challenges into clear, actionable solutions that strengthen community resilience. She also champions evidence-based engineering policies that advance public safety and long-term infrastructure sustainability.
Outside of work, Christina enjoys spending time with family, listening to audiobooks and various podcasts, attending live music events, and exploring new places through travel.
