Bio Representative Matters Speaking/Writing Of Note

Nicole R. Gleason is a partner at Diepenbrock Elkin Gleason LLP, and leads the firm’s national environmental law practice. She is uniquely versed in environmental agency enforcement actions, brownfields redevelopment, environmental compliance, environmental due diligence, grant programs, cost recovery litigation and environmental insurance. As Nicole’s representative experience reflects, she has deep experience with complex, multimillion-dollar remediations involving former military bases, landfills and disposal facilities, railyards, manufacturing and storage facilities, regional-multisource plumes as well as smaller dry cleaning and gas station sites. Nicole was also one of the key negotiators of SB 445, which extended and expanded the grant programs available in California for contaminated sites and became effective on September 25, 2014. Since then, Nicole has remained active in a number of legislative and state policy advisory groups that are working to improve contaminated property grant programs. Regardless of the size or nature of the project, she creatively and efficiently realizes her clients’ objectives by being equal parts advocate, advisor, interpreter, connector and PR coordinator.

In 2016, Nicole was honored to be invited to join Lambda Alpha International, a honorary, non-political professional society devoted to the advancement of land economics.  In addition, and as a result of her years of experience in environmental law, Nicole was recognized by the Sacramento Business Journal and her peers as one of the “Best of the Bar” in 2015, 2016, and 2017 and as a mentor for the Business Journal’s Mentoring Monday.  Sacramento Magazine and her peers also honored Nicole as a “Top Lawyer” in her field in 2016, 2017 and 2018. Nicole was named a Rising Star in 2009 and a Super Lawyer in 2011, 2016, 2017 and 2018 by her Northern California peers.  In addition, she served as the Vice Chair of the Executive Committee of the California State Bar’s Real Property Law Section (RPLS), and was qualified as an expert on the California UST Cleanup Fund.

Nicole obtained her B.A. in Political Science with a minor in Planning and Development from California State University, Chico. During that time, she volunteered as Environmental Law Director – and then Administrative Director – for the Community Legal Information Center (CLIC) and served as an outdoor guide for Adventure Outings.  She earned academic honors while obtaining her J.D. degree from McGeorge School of Law with distinction, served as a member of both the Traynor Law Society and the Environmental Law Society, and was an editor of the University of the Pacific Law Review.
