Mr. Noe specializes in RiverWare© model development and the development of technical tools to help clients make informed decisions on the water resources. Prior to his tenure at Precision, Mr. Noe spent several years in Austin focusing his time on both non-profit youth work and videography before deciding to pursue a career in water resources planning and management. Send Patrick an email >

Brett Boyer, BS // Water Resources Engineer

Brett Boyer received a B.S. in Mechanical Engineering from the University of Utah in Salt Lake City. During his time as an Engineering student, he became interested in Water Resources while working as a technician on an NSF research project known as “Innovative Urban Transitions and Aridregion Hydro-Sustainaibilty” (iUTAH). Directly after graduation he left the field to work as a Control Systems Engineer on a gold-mining project, but joined Precision in the Spring of 2020 to start a career with a stronger environmental focus. Mr. Boyer is an expert in RiverWare® modeling and specializes in developing and maintaining utilities to help Precision Engineers and clients interact with models and visualize results.

Benjamin Abel, PhD // Water Resources Engineer

Dr. Abel received a BA in Music from Westminster College in New Wilmington, Pennsylvania. He then moved to Los Angeles, California and spent six years in software quality assurance before deciding to return to school. He moved to Colorado in 2013 to attend the University of Northern Colorado in Greeley where he received his MA in Earth and Atmospheric Sciences. Then, he received his PhD in Civil Engineering from the University of Colorado at Boulder. His diverse, interdisciplinary background includes climatology, data science, numerical modeling, and programming. During his time at CU, he gained experience with RiverWare, and he will continue development of RiverWare models to assist in water resources management with Precision. He will also use his climatology and data science knowledge to help clients better understand how climate and hydrologic data affect and inform water resources management. Send Ben an email >

Leland Dorchester, M.S. // Water Resources Engineer

Leland received a B.S. in Geology from Colorado State University (CSU) in Fort Collins, CO. During his undergraduate studies, Leland became interested in water resources while working as a field and laboratory technician in the fluvial geomorphology laboratory at CSU. He then gained experience working in environmental consulting at sites across Colorado. In the Fall of 2020, Leland returned to school to pursue a Master of Science in Hydrologic Science and Engineering from Colorado School of Mines (CSM), where he gained experience in numerical and analytical hydrologic modeling techniques. Upon finishing at CSM, Leland began working at Precision as a Water Resources Engineer in 2022. With Precision, he will work on developing RiverWare© models that provide support to water resources management decisions. In his time away from work, you can usually find Leland in the outdoors skiing, mountain biking, or climbing in the Colorado Rocky Mountains. Send Leland an email >

Lianne Daugherty, M.S. // Water Resources Engineer

Ms. Daugherty received a B.S. in Civil Engineering from the University of Nebraska-Omaha and worked as an environmental engineer for three years.
