Nathan O’Leary, PG, CHMM

Project Manager


Nathan graduated from Iowa State University in 2004 with a Bachelor of Science in environmental science. Since graduating, Nathan has worked for consulting firms in New Jersey, Iowa, and North Carolina and was fortunate enough to join Hart & Hickman in 2010. Throughout his career, Nathan has worked on due diligence, compliance, site assessment, site remediation, Brownfields, and state-lead projects across the country and most often in California, Colorado, Texas, North Carolina, and South Carolina. The aspect that Nathan enjoys most about his career at Hart & Hickman is the range and volume of projects and the opportunities that it presents for professional growth.

Nathan has been married to his amazing wife Karen for almost 10 years and is lucky to be the father of two beautiful and hilarious girls Kaia and Sydney. In his free time, Nathan enjoys gardening and yard work, hiking, reading, fishing, disc golf, and spending time with his family. Fun fact – Nathan is an Olympic curler stuck in a consultants body.
