What Cornerstone Staffing Solutions, Inc. does

Cornerstone Staffing Solutions, Inc. is a privately held US staffing and recruiting firm headquartered in Pleasanton, California, founded in 1996. The company provides temporary, temp-to-hire, and direct hire placements across seven vertical specializations: administrative/professional, manufacturing and light industrial, healthcare, engineering/technical, call center, sales and business development, and human resources. It operates a multi-brand platform with three specialty subsidiaries — RightStone (IT and technical staffing), Arlington Resources (HR professional staffing, based in Chicago, acquired January 2018), and Casey Accounting and Finance Resources (finance and accounting placements) — allowing the firm to serve both commercial/industrial clients and higher-margin professional verticals under one corporate umbrella.

The company serves enterprise and mid-market employers through branch offices in Pleasanton, Sacramento, and Fremont (California) plus Davison (Michigan) and Baltimore (Maryland), and through onsite managed-services partnerships embedded at client facilities across Southern California, Arizona, Utah, South Carolina, Michigan, and New Jersey. The technology stack is built on the Avionte staffing platform, supporting both client-facing operations (job portal, candidate application system) and internal workforce administration (My Cornerstone staff portal for pay history, W-2 access). The revenue model is a professional-services markup on temporary wages, supplemented by conversion fees on temp-to-hire arrangements, placement fees on direct hires, and managed-services revenue from onsite staffing contracts.

Cornerstone has accumulated 18 ClearlyRated awards since 2016, including Diamond status recognizing 5+ consecutive years of Best of Staffing wins (an award achieved by fewer than 1% of US and Canadian staffing agencies), with documented client satisfaction scores of 70.1% at 9-10/10 (vs. 41% industry average) and a Net Promoter Score of 62.6% (vs. 29% industry average). Leadership transitioned in February 2023 when Mike Mitchell — a 40-year industry veteran who previously grew ProDrivers from $100M to over $200M as Division President — took over as President and CEO, accompanied by a refreshed C-suite including CFO Brenda Massey (2023), VP Strategic Partnerships David Bishop (2023), and VP West Joan Van Donge (2022). The firm was previously led by Steve Drexel, who was named to SIA's 100 Most Influential in Staffing list in both 2013 and 2016.
