Services and Capabilities

Pinnacle is a general partnership comprised of two experienced geological professionals. As such, a standard company organizational chart is not applicable. All projects are managed directly by either Mr. Keith Thompson or Mr. William Malvey. 

Pinnacle’s special expertise is the ability to respond rapidly and with great flexibility to the changing needs of our clients. Pinnacle has the proven ability to complete project work in virtually any location in the United States. Our personnel have successfully coordinated the scheduling, logistics, and completion of field activities at locations throughout the country.  

Pinnacle has developed numerous positive working relationships with experts in their respective fields. These relationships are utilized as necessary to provide an expanded range of services on an as needed basis. This approach keeps overhead costs low and allows Pinnacle to respond to varying project needs while maintaining a competitive cost structure. When required, Pinnacle has the proven ability to provide the services of qualified toxicologists, groundwater modelers, a variety of engineers, and construction professionals. Our extensive experience in southern California enables us to readily identify and subcontract those professionals who can be called upon when needed to assist in special problems presented by unique projects.
