Mr. Jehn has appeared as an expert witness in over 70 cases involving water rights, ground water modeling and geophysical logging. Mr. Jehn is skilled in working with multi-disciplinary, long-term water resource teams.

Ms. Theresa Jehn-Dellaport, PG: Ms. Jehn-Dellaport has over 20 years experience as a Project Manager working as a hydrogeologist for diverse water resource projects. She specializes in Colorado water rights issues, which include both surface and ground water. She has been an expert witness for water rights and environmental matters. Ms. Jehn-Dellaport has completed an aquifer storage and recovery well project for a major metropolitan district. This project was awarded the outstanding project for ground water supply (1998) from National Ground Water Association. Ms. Jehn-Dellaport is pioneering directional water well drilling for large production wells.

Ms. Gina Burke, CGWP: Ms. Burke has over 10 years experience as a hydrologist and project manager with Jehn Water Consultants.
