When disputes, claims, or regulatory matters involve complex technical issues, attorneys and clients need more than opinions—they need clear, well-documented, defensible analysis from experienced professionals. Souder, Miller & Associates provides professional witness and related litigative support services for matters involving civil engineering, environmental conditions, surveying, mapping, infrastructure, site development, water resources, construction, and land-related technical issues.

SMA brings decades of practical project experience to legal and administrative proceedings. Our engineers, environmental professionals, surveyors, GIS specialists, and technical staff support public agencies, private clients, tribal entities, developers, utilities, contractors, insurers, and legal counsel with objective technical review, documentation, and testimony support.

Serving clients across New Mexico, Arizona, Colorado, Texas, Utah, and Wyoming, SMA offers regional knowledge, multidisciplinary perspective, and practical understanding of the technical standards, field conditions, regulatory environments, and project delivery challenges common throughout the mountain west region.

Legal Support Grounded in Real Project Experience

SMA's professional witness services are built on the same foundation as our consulting practice: sound technical judgment, careful documentation, and clear communication.

This project-based experience helps us evaluate technical issues in context. Whether the matter involves a construction dispute, environmental impact, boundary or survey issue, infrastructure failure, design question, standard-of-care review, or regulatory compliance concern, SMA can help legal teams understand the facts, organize technical evidence, and communicate conclusions in a clear and professional manner.
