Mr. Craig's professional career spans 33 years. He is an experienced project manager and technical hydrogeologist with expertise in all aspects of groundwater supply. He has expertise in advanced quantitative analysis including application of almost all groundwater flow and solute transport models. He is an original MODFLOW and MT3D user and an advanced user of GMS.

Dan has been involved in numerous groundwater supply projects including private and municipal supply well and aquifer recharge systems. He is experienced in hydrologic data collection; construction of groundwater supply, injection, and monitoring wells; and design of pumping and treatment systems. Dan has also worked on numerous groundwater contamination and site remediation projects, and routinely evaluates fate and transport of solutes in groundwater. He has conducted strategic analysis and planning on behalf of a variety of clients, including water and wastewater agencies, private companies, legal counsel, and federal, state, county, and city governments. He has been designated as an expert witness for several groundwater lawsuits.

In recent years, Dan has assisted the several South Bay municipalities in developing their local groundwater supplies. He managed the planning, design, construction, and operation of new municipal wells in the Cities of East Palo Alto, Menlo Park, Santa Clara, San José, and for the Counties of San Mateo and Santa Clara. Dan has also recently completed several managed aquifer recharge projects that included the design, construction, and operation of new spreading basin and injection well facilities. Since 2014, Dan has assisted the Coachella Valley Water District (CVWD) with numerous projects including start-up and optimization of operations at the Palm Desert and Thomas E. Levy recharge facilities. For these projects Dan designed and constructed local transient MODFLOW and MT3D groundwater models to predict future flow and groundwater quality changes. Dan has also designed and managed construction of monitoring wells for the recharge facilities. In 2019, Dan began assisting CVWD with preparation of their Sustainable Groundwater Management Act (SGMA) Groundwater Sustainability Plan (GSP) Update, that includes updating and upgrading CVWD's basin-wide groundwater flow model.
