Why are you a part of CDM Smith? CDM Smith lives and breathes our core value of technical excellence, and our matrix organization allows us to put the best and brightest people on every project no matter where they “reside” across the world. We have deep technical knowledge across the firm, and we focus on knowledge sharing and mentoring to ensure that we are bringing up the next generation of technical experts.
Why CDM Smith? Because CDM Smith values technical excellence, leadership and community. Our environmental work is designed to facilitate developing integrated, multi-disciplinary project teams with strong interpersonal and professional relationships built on mutual trust and respect to develop the best solutions for our clients.
What’s a project or accomplishment that you’re particularly proud of, and why? We are nearly finished building a pilot plant for a PFAS-destruction treatment train using foam fractionation to concentrate PFAS from dilute water streams, electrochemical oxidation to destroy PFAS and a perchlorate polish to provide a complete solution for water treatment. Our approach has the potential to leverage synergistic technologies to provide a more sustainable solution for PFAS treatment.
What’s your personal motto? Be kind, work hard, no excuses.
What is your favorite part of your job? I love solving puzzles and I love our natural environment. My job allows me to marry these two elements to come up with ways to clean up hazardous chemicals and restore our natural environment. Often, restoring contaminated sites is like complex puzzle that requires building multi-disciplinary project teams to understand site conditions, and then identify appropriate solutions. Because of this, I continually learn and grow with every project and get to see success as we work through each step of the cleanup process.
I hold everything we do to the highest standard and strive to go the extra mile to exceed expectations.
