Mark Easter, P.E., is a licensed Professional Engineer with more than two decades of experience evaluating buildings, infrastructure, and environmental systems. He received a BS in Engineering from the University of Oklahoma, and a Master’s degree from Southern Illinois University. His work focuses on building diagnostics, structural performance, with particular experience in foundation behavior, moisture intrusion, and building-envelope issues common to Texas soils and climate.
Mark’s engineering background includes as an Air Force engineer, engineering design and his own private practice, In those roles, he evaluated structural systems, utilities, and site conditions; reviewed engineering designs and construction activities; and managed programs affecting long-term asset performance. He has also served in project and program manager positions and Air Force Base-wide programs and systems. This gives him strong grounding in risk assessment, data interpretation, and technically defensible decision-making.
In private practice, Mark specializes in structural evaluations of residential and light-commercial structures, with an emphasis on slab-on-grade and pier-and-beam foundations, differential movement, drainage impacts, and moisture-related issues, His approach is diagnostic rather than prescriptive: identify root causes, separate cosmetic issues from structural concerns, and clearly explain findings in plain language.
Clients value Mark’s ability to bridge the gap between engineering rigor and real-world practicality. His reports are thorough, unbiased, and written to stand up to scrutiny. He brings a systems-based perspective to every project, understanding how soils, structure, moisture, and construction practices interact over time.
