What does Service, Trust, and Purpose mean to you?

To me: SERVICE involves working hand-in-hand with clients to create a resilient and secure future for their communities. TRUST is built by demonstrating commitment and expertise, working together and finding innovative solutions that consistently meet and exceed expectations. PURPOSE fuels my motivation to resolve water management issues in in the arid West and my drive to serve my colleagues, company and clients.

Keys to your success?

Communication, energy and execution. I enjoy communicating with people at all levels internally and externally; listening to other’s needs and striving to find alignment amongst competing interesting. I bring positive energy to each interaction; striving to sustain an optimistic yet measured outlook from the start to the end of each project. I do what I say I am going to do, which sometimes means I have to say “no” – not an easy thing to do – but allows me to ensure that I can deliver on my promises.

What are you passionate about?

I have a passion for balancing sustainability with engineering. At an early stage in my career I became a LEED Accredited Professional, to demonstrate my commitment to finding solutions that balance economic, environmental and social goals. My high school physics teacher told me I could save the environment with math and physics, so I became an environmental engineer. Over my career I have transitioned between engineering natural treatment systems, like wetlands, to advance treatment systems for potable reuse of municipal wastewater; saving the world one drop at a time for future generations.
