Technical Advisory Council

I am a passionate advocate for all things associated with assessing and renewing our aging water and sewer infrastructure. Being a certified trainer for nearly the past 20 years, I am proud to continue serving my industry peers as Chair of the Technical Advisory Council.

Veronica Alvarez

I am dedicated to driving innovation and efficiency in critical water solutions. My 17-year career includes domestic and international projects, specializing in large-diameter pipelines and master planning. I am committed to mentoring underserved youth in STEM, encouraging them to pursue careers in our industry.

Eric Haenlein, P.E.

I have been a member of NASSCO for five years and am most active with the Pipeline Rehab Committee and the Technical Advisory Council. A licensed professional engineer in 12 states, I help the Puris Corporation with design challenges and client engagement.

Chris Macey, P.E.

Where I come from (Winnipeg, MB), they have practiced trenchless as a “way of life” for a long time, so I have been at it and fascinated with condition assessment/rehabilitation for over 40 years. In the past couple of years Lynn Osborn and Sheila enticed me to get involved with TAC, expanding it from one to a Team. I’ve been hooked ever since.

Dennis Pivin, CSP
