Roger Failmezger, P. E., F. ASCE

Roger attended Lehigh University for his B.S.C.E., which he received in 1981, and in 1982, he earned his M.E.C.E. from the University of Florida.   As a Professional Engineer since 1986 with significant contributions to geotechnical engineering, Roger was appointed as a Fellow by ASCE in 2006.  He is licensed in Virginia, Maryland, and Pennsylvania.

Many have sought to have Roger speak on the necessity of In-Situ soil testing for good engineering design work.   Some of his talks are listed below:
