ENGINEERING GEOLOGIST
______________________________________PROFESSIONAL PROFILE______________________________________
• Project Management experience in all aspects of engineering geology. Includes all phases of projects from
conceptual feasibility, through design, and construction.
• Experienced in leading projects in many disciplines including civil, transportation, mining (including
underground), dams, water conveyance, and environmental.
• Possesses a keen understanding of how a particular site’s geologic characteristics will affect a project’s
engineering, design, and construction. Uses this understanding to create the best plan for geotechnical
data collection and analyses.
• Experienced in leading projects in all types of terrain and environments, from extremely rugged remote
sites to sites in crowded urban settings.
• Experienced in many types of forensic investigations.
• Accomplished technical writer.
• Possesses extensive experience in predicting project costs and creating project budgets as well as
managing costs to stay within those budgets.

Senior Engineering Geologist, Saguaro GeoServices, Inc., Tucson, AZ, 2003 to 2014
As a Senior Engineering Geologist at SGS, it being a very small firm, I was responsible for performing all aspects
of project work. On a typical highway design I prepared proposals, cost estimates and budgets; obtained permits,

prepared subcontracts, managed logistics, and scheduled field work; did all core and soil logging, mapping, and
other field activities; managed all subconsultants; processed and reduced all data collected, performed
engineering analyses, and prepared all reports. During construction I monitored excavation and slope stability.
Typically this would involve inspection of the blast hole pattern, loading, and timing. As blasting proceeded and
slopes were exposed, I would inspect them and recommend areas for scaling and or rock bolt installation.
Notable projects managed during my tenure at SGS include:
• SR87 – Segment AB – Design and construction of a new, approximately 4-mile-long northbound
alignment through extremely rugged mountainous terrain north of Fountain Hills, AZ. Included cut
slopes of up to 300-ft in height in a complex igneous geologic environment.
• US60 – Top of the World to Pinto Valley Road – Design of the widening of an existing rural highway
between Superior and Globe, AZ. The project involved widening the existing highway through a
geologically varied and culturally sensitive area. It included 100-ft + cuts and very high fills.
• Cerro Jumil Gold Mine – Tetlama, Morelos, Mexico – Slope design for a 300-m-deep open pit mine.
Designed and performed a program of oriented core drilling and fracture mapping. Performed
probabilistic kinematic, back-break and global stability analyses to determine maximum bench face and
inter-ramp angles for the different pit sectors.
• Golinski Mine AMD Mitigation – Lake Shasta, CA. Remote (no road access) abandoned mine emitting
AMD into Lake Shasta. The project involved rehabbing access into the multi-level mine, mapping the
geology and workings, remote measuring of seasonal flow rates, design of a bulkhead to pool AMD
inside of the mine, and design of an artificial wetland to neutralize the AMD metered out of the
bulkhead.
Manager of Geotechnical Engineering, Pattison Evanoff Engineering, Tucson, AZ, 1998 to 2003
At this locally owned soils engineering and testing firm I managed the geotechnical engineering department. I
was responsible for writing proposals, designing exploration programs, selecting of samples for laboratory
testing, performing analyses and designs (primarily for foundations, slabs, pavements, and septic systems), report
preparation, scheduling, and budgets.
Senior Engineering Geologist, Engineers International, Inc., Tucson, AZ, 1990 to 1998
At this small geotechnical/geological engineering firm I worked with engineers in developing project designs.
Typically, I would perform fieldwork and provide all geologic data and analyses to the engineers for final design.
Geologist, US Bureau of Reclamation, Vernal, UT and Tucson, AZ, 1982 to 1990
At the BoR I worked as a staff geologist on water conveyance projects (CUP and CAP). This included dams,
tunnels, canals, pipelines, and pumping stations. I performed geologic mapping, field subsurface exploration and
detailed geologic mapping during construction.
Geologist, USDA Forest Service, Gold Beach, OR, 1980 to 1982
Working in the West Engineering Zone of the Siskiyou National Forest, I was responsible for road alignment
evaluation and roadway design studies, landslide inventories, landslide remediation, and aggregate source
evaluations.
Geologist, US Corps of Engineers, Tulsa, OK and Los Angeles, CA Districts, 1978 to 1980
For the CoE I was primarily a field geologist logging core and performing hydraulic testing.
