Professional Experience:

Geoff is a member of the Board of Directors and the Southwest Regional Manager. He is responsible for directing and supervising the financial and operational performance of the region. Geoff manages a staff in Austin, Texas that provides monitoring and consulting services in 15 western states.

Geoff previously served as Technical Sales Coordinator where he supported all the GeoSonics/Vibra-Tech regional offices, working to continuously improve market position and achieve financial growth by pursuing sales leads and perspective clients. He delivered presentations and proposals to assist clients in strengthening their risk management strategy. Geoff also worked to maintain key client relationships with regional and national accounts.

Geoff has worked to develop our Re:mote monitoring services by helping design new web-based data management features on special projects. These features have helped clients track specific aspects of the drilling and blasting program as defined by the end user. He continues to help clients institute best practices and assist in continuous improvement initiatives.

Prior to moving into the Technical Sales Coordinator position in 2010, Geoff served as a Geologist, managing regional mining and construction projects for the St. Louis office. With his background in geology and geophysics, Geoff worked to expand the market for GeoSonics/Vibra-Tech’s geophysical imaging services.
