Liz has made an impact from the first day she joined the Big Rock team. She brings a great mix of passion, inquisitiveness, determination, and work ethic. She is knowledgeable, poised, and vigilant in all project environments. A commitment to uphold our core value of safety and ensure the Big Rock standard of operational excellence shines through in her work. Whether in the office or in the field, she is a tone-setter with effort and proactiveness. The completion of her tasks isn’t the end of the workday, as she always looks for opportunities to advance team goals or help others.

Liz is a sharp, thorough scientist who’s tremendous attention to detail with data and reporting ensures high-quality deliverables and client outcomes. When faced with uncertainty or project challenges she brings an effective, solution-minded approach. She takes pride in being a reliable, accurate communicator in all situations. Her support of others elevates team cohesiveness and makes cooperation a huge strength.

In September Liz was recognized for her outstanding contributions in four key criteria that enable successful programs.

Congratulations and thank you on behalf of Team Big Rock!
