Diana Lynn Muller, Executive Director

Diana brings with her a thirty years hands-on environmental professional work experience, from being a field-lab tech to directing science and policy, with many peer-reviewed publications and technical reports.  She is on the Board of Directors of the Maryland Water Monitoring Council, EPA Chesapeake Bay Program’s STAC Land-Water steering workgroup, and EPA Chesapeake Bay Program’s Climate workgroup.  Diana holds a MS in Environmental Policy from Johns Hopkins and a B.S. in Environmental Chemistry from Evergreen State College.

Diana grew up on the shores of Puget Sound in Olympia, Washington to a family of watermen and loggers.  The boat the she “grew-up” on was a 1956 Mansfield with the old Mahogany deck.  Summers were spent working on the water with her dad to fish, oyster, clam, and crab.  By the time, she was 12 she had her own boat, and in college she was chartering college friends salmon, rockfish and halibut fishing.  Today she holds a 100T USCG license.  She became interested in marine biology at the age of five, due to the fishing, whale watching, camping, and hiking through out Puget Sound, Hood Canal, and Straits of Juan de Fuca.  During her teen years, the fish in the local area had cancerous lesions on them, so she became interested environmental chemistry.  She graduated with a B.S. in Environmental Chemistry and Environmental Policy.  Diana then drove her old 1963 Plymouth Fury across the country to graduate school at Old Dominion University and worked for the lower Chesapeake Bay and Elizabeth River water quality-monitoring program.  She then worked at Virginia’s Aquarium as the lab manager and was part of the stranding team.  She met her husband (Andrew Muller) at ODU and they were married in 1992.  Andrew finished his Ph.D. in oceanography and Diana was expecting their first child in 1998, when careers moved them to Lancaster, Pennsylvania.  Diana became the QA/QC specialist at Lancaster Labs.  They spent 10 years researching the water quality of the Susquehanna, Conestoga, and smaller tributaries while living in Lancaster County, and the upper region of the Chesapeake Bay.  Then in 2007, another career opportunity moved Diana and Andrew to Annapolis, Md.  Diana became the Director of Science & South Riverkeeper for the South River Federation, and Andrew became a professor of oceanography at the United States Naval Academy.  Diana spent eight years at the Director of Science, bringing the “gold-standard” water quality monitoring to a small nonprofit and writing peer-reviewed publications on what is now known as “triblet” science.  She testified in legislature, and county council over many environmental topics during that time.  She then moved on the teaching for a few years environmental science in the Anne Arundel County schools.

Diana was enticed by Chesapeake BaySavers’ uniqueness of taking science, outreach, and education to make positive policy and legislation for a healthier Bay, and has a vision for a swimmable and fishable Bay.

Diana and Andrew have two children: Arianna who is an environmental science major in college and her son (Keaghan) who is currently an IB student at Annapolis High.  They also have two dogs, a chocolate lab- Daisy, and a mini-St. Bernard-Brandy.  During her “off-time,” Diana trains for ½ marathons, kayaks, gardens, and goes hiking with her family.
