Our firm traces its roots to the founding of S. E. Medall & Associates, Inc. in 1973. Mr. L. Fernando Aragón partnered with Mr. Medall in 1979. Over the course of more than three decades of professional consulting services by the original partners and other principals, the company weathered multiple economic cycles by maintaining a focus on uncompromising quality and client’s needs. Aragon Geotechnical, Inc. (AGI) is a successor to Medall, Aragón Geotechnical Inc., formally renamed in 2009 and now led by a second-generation principal, Carlos Fernando Aragón.
