Craig M. Lis

Senior Water Rights Engineer

Craig M. Lis, P.E., joined Martin and Wood in August 2010 and has more than 30 years of related experience. He is directly involved in the review of water court applications, associated engineering reports and proposed rulings for Applicants and Opposers, and preparation of expert disclosures for the water court. Craig also works on Alternative Transfer Mechanisms including leasing-fallowing projects in the Arkansas River basin, as an alternative to the purchase of historically irrigation lands and then the subsequent dry-up of that land to support water user somewhere else (“buy and dry”). Craig's previous 24 years of experience include performing reviews and engineering analyses, and providing recommendations related to the adequacy of proposed water supplies and potential injury to decreed water rights, water court and litigation issues, surface and groundwater hydrology, and groundwater and surface water computer models.

Craig's experience also includes review and approval of substitute water supply plans and well permit applications, acting as a liaison between clients and other water users, state and federal agencies, and negotiating terms and conditions for water court decrees.

William R. BerG

Senior Hydrogeologist

Bill Berg, P.G. joined Martin and Wood in 2005 and has been working in the surface and groundwater fields since 1997. Bill has technical expertise in water supply and water rights, groundwater wells, environmental remediation, mining, solid waste, and power sector projects. He has extensive experience in the design, implementation, and management of hydrogeological field investigation programs including the design and construction observation of shallow wells, deep wells, monitoring, and observation wells along with water quality sampling, analysis, and interpretation. Bill’s work has included the design and permitting of coal bed methane (CBM) water discharge systems in the Powder River Basin in Wyoming. He has conducted field sampling of surface water and coal bed methane water outfalls in coordination with geochemical evaluations. His past work has also included the evaluation and design of remedial alternatives.

His computer modeling experience includes three-dimensional finite difference groundwater flow modeling for the evaluation of well depletion effects on surface water stream systems. He also has extensive experience with comparative statistical analyses.

Our Founders

Joe Tom Wood

Joe Tom Wood & Phil Martin started Martin and Wood in 1991. As an engineer and hydrogeologist team, Joe Tom specialized in surface water resources and Phil Martin specialized in groundwater resources. Joe Tom and Phil built M&W into the company it is today by developing trusting relationships with our long-term clients, providing excellent service, and mentoring our staff.

After many years of dedicated service, Phil retired in 2012 and Joe Tom retired in 2017. Phil retired to Florida where he spends his time sailing, playing piano, volunteering with Engineers without Borders, and traveling with his wife Madie. Joe Tom retired to California where he spends his time reading books, taking classes at Stanford, going for walks, and spending time with his wife Holly and his 7 children and 11 grandchildren. Today M&W strives to honor Phil and Joe Tom’s legacy by providing exceptional water resource engineering and hydrogeological services in Colorado.
