Mrs. Halley brings four decades of regulatory/permitting strategy, civil engineering, and program management to Cornerstone’s clients. A Penn State graduate (BSCE ’81), she assists in regulatory agency interface, strategizing on CEQA compliance, and water resource engineering. She is a sought-after consultant on matters of California energy policy. Mrs. Halley holds a particular expertise in Underground Injection Control compliance. She has proven herself to be an adept communicator of technical settings to a variety of audiences, including elected officials, agency representatives, and the public.

In the early 2000’s, Mrs. Halley was Utilities Division Manager for San Luis Obispo County, responsible for a team of 32 professionals in operating the County’s utility and water supply systems. Of particular note was Mrs. Halley’s years of participation in the $180 million Nacimiento Water Supply Project for San Luis Obispo, the largest public works project undertaking by that agency at the time.

Arguably among the most connected professionals in the San Joaquin Valley, Kent Halley brings more than 35 years of management, sales, and marketing to Cornerstone. But he brings much more than that. Kent holds a reputation for understanding client resource needs and drivers, then aligning the right professionals for the job. He has personally played a role in placing well over 200 professionals into mid- and upper-level technical and managerial positions. In doing so, Kent repeatedly succeeds in bringing top-notch talent into the Cornerstone team on behalf of our clients.

Industry practice areas in which Kent has played a key role include energy, industrial, mining, land development, and technology. His networking with senior staff for the region’s top employers and influencers make him an effective professional, and strengthens Cornerstone’s market strategy.

Kent’s community involvement includes board seats on Cal State Bakersfield Engineering Advisory Board and Cal State Bakersfield President’s Community Ambassadors Council, Kern Venture Group Executive Board, and Deaf Haiti charity for education of deaf children. Financial sponsor of “B3K”, Beautiful Bakersfield and Boundless Kern, an organization engaged in regional prosperity. He is also an active member of Laurelglen Bible Church.

Educated at Rio Grande University in Ohio, Kent holds degrees in chemistry and mathematics with course emphasis in business management. Industry work includes U.S. Sales and Marketing Manager for Emerson Electric Corp in the 1990’s followed by a marketing manager position for Systems Measurement Services in the years following that. As principal at TJCross Engineers, Inc. in Bakersfield, CA, for 16 years, Kent forged engineering alliance partnerships with the area’s larger oil & gas producers. He carried on that role in the years following the acquisition of TJCross Engineers by Parsons. In 2018, Kent partnered with Derrill Whitten at Cornerstone and to date, Cornerstone has grown from a civil engineering team of seven to a multi-disciplinary team of approximately 80 people.

Derrill Whitten began his career here at Cornerstone in 1990 and is the thread of continuity for our service set over the decades. He anchors Cornerstone’s civil engineering and land development services and provides subject matter expertise to our surveying department. Unique among his colleagues, Mr Whitten not only holds his civil engineering license, but he is also a registered professional land surveyor and a Grade V wastewater treatment plant operator. This rare combination of education (BS in Petroleum Engineering from University of Texas at Austin) and licensure brings well-rounded critical thinking to Cornerstone clients.

For a decade beginning in the mid-1990’s, Mr Whitten worked for a consulting firm in his home state of Oklahoma and the City of Bakersfield Public Works Dept. Those assignments in particular blended utility operation and capital planning skills with his technical training. As a result, Mr Whitten has been brought in to manage city-wide wastewater capital planning, treatment plant upgrades, street improvements, and campus improvements for community college district facilities. More importantly, he brings continuity and a family atmosphere to the Cornerstone team and to our long-time clients.

Formally educated in engineering and business with experience in operations and strategy, Mr. Dhanens adds an organized and well-rounded perspective to the consulting of energy and infrastructure. As the Natural Resources lead at Cornerstone, Eric performs long-term strategic plans at the intersection of economics, technology, and regulatory policy; making sense of the complex energy landscape for our clients.

Rolf Scherer brings a breadth of experience to the Cornerstone team that has accumulated over his diverse career. Since receiving his BS degree in Mechanical Engineering from Cal Poly San Luis Obispo, he has spent the last 30 plus years working in California’s top industries of Agriculture and Oil & Gas.

Rolf began his career with a large citrus fruit processor in Ventura, CA, where he managed capital projects, maintenance of mechanical and process systems, held responsibility for energy contract negotiations and budget preparation. He then dedicated twelve years as Process Engineer and Environmental Specialist for San Joaquin Refining Co. in Bakersfield, CA. He was project manager over the expansion and replacement of capital equipment and assessed system needs for a variety of refining processes, including analyzing project feasibility and economics. It was with Grimmway Farms that Rolf first took on a role as Director of Project Operations, leading a team of engineers and mechanical designers to develop and implement capital improvement projects for all company facilities across the country. Rolf oversaw power and natural gas energy purchasing, annual capital expenditure planning, master construction schedule and resource planning as part of the divisions’ senior leadership team.

Cornerstone clients know Rolf well in his role as Director of Project Operations. He sets standards for Cornerstone’s project managers and serves as a senior resource for our mechanical engineers and designers. But chances are that if you asked Rolf, he would speak of none of this, but rather share proud stories of his family, his adventures as a leader in Boy Scouts of America Troop 194, and the kids who he has coached in soccer and baseball over the years.
