NRWA Mission and NRWA Board Bios

NRWA Mission

The Norwalk River Watershed Association, incorporated in 1996, is a not-for-profit membership organization whose mission is to improve the water quality and fish and wildlife habitats of the 40,000-acre Norwalk River watershed; to restore the riverbanks, meadows and forests through invasive plant abatement and promotion of native species; to encourage recreational use of the river, the surrounding open space and its trails; and to promote research, legislative advocacy, education, cooperation, and action on the part of the stakeholders in the seven watershed towns in CT (Ridgefield, Redding, Wilton, New Canaan, Weston, and Norwalk) and NY (Lewisboro).

We are working to help implement the Norwalk River Watershed Action Plan.

David Havens, Vice President, has been a lifelong resident of Connecticut, splitting his time between Norwalk, Stamford and New Canaan and serves as the Vice President of NRWA.  After growing up along the Norwalk River, Dave spent six years conducting full-time environmental fieldwork from 1971 to 1977, while also working for the Stamford Museum and Nature Center. Since 1977 Dave has worked as a science teacher for Pre-K students to Graduate Studies. He has been an active voice for environmental issues locally and nationally, working with several organizations such as Greenpeace, Earth First!, Audubon, Green Schools Alliance and NRWA. Along the way Dave earned two BS degrees and three graduate degrees in science as he continued to conduct research on a number of issues: Invasive Species, Open Space, Habitat Destruction, Breeding Bird Census and much more. Over the last few years, he designed and built a raised outdoor classroom and boardwalk through his school’s wetlands, developed a plan to eliminate 14 species of invasive plants that gained a strong foot hold on the property and taken his passion of teaching and environmental work to an international level with the Green Schools Alliance. In 2012, David and his students were selected as state finalist in “Siemens We Can Change the World High School Challenge, sponsored by Siemens Foundation, Discovery Education, the National Science Teachers Association (NSTA), and the College Board”, for their efforts to selectively and safely exterminate invasive plants along the Norwalk River.

Laurie Mirra teaches yoga and works to restore wildlife habitat and protect water quality in South Norwalk. Laurie moved to the Village Creek neighborhood ten years ago and has been advocating since then for environmental protections in that community, encouraging homeowners to stop using pesticides on lawns, to use nontoxic mosquito/tick treatments, to plant for pollinators, to help her start a tree planting program, and to protect healthy trees.  Much of her energy in the last five years has focused on restoring Woodward Avenue Park in South Norwalk which lost most of its trees during hurricane Sandy. As neighborhood liaison to the city of Norwalk’s Tree Advisory, she has long advocated for restoring the tree canopy in South Norwalk. She helped organize a collaborative effort by NRWA, Village Creek, Recreation and Parks, and the Department of Public Works to remove invasives and plant native shrubs and trees, transforming Woodward Park.  In addition, the park’s new garden is now part of the pollinator pathway. Plans to connect Woodward and Oyster Shell Parks through a corridor of pollinators-friendly trees is one of the NRWA projects she is helping spearhead. As a yogi, Laurie says she lives by the practice of ahimsa or non-harming, which is an important part of an ancient philosophy that includes the practice of compassion for all living things. Ahimsa means not harming the complex web of nature that connects us all, including plants and trees, water and air, and our pollinators. She also is inspired by Doug Tallamy’s ideas around enriching biodiversity and protecting our environment, starting in our very own backyard.

Kristin Quell-Garguilo grew up in Westchester County to a family of tree nurserymen and has always been fascinated with the balance of nature and environmental systems. She has a Master’s of Science in Sustainable Systems, a Bachelors of Science  in Geology and one in Environmental Science, and Certifications in Ecosystems Services, Plant Based Nutrition, and Hazardous Waste Material. She has been teaching as Professor of Energy Systems since 2008. After moving to Ridgefield, she began volunteering for environmental causes in and around the area.  This led her to joining the Board of the Norwalk River Watershed Association where she is excited to combine her scientific expertise and her passion for environmental conservation.  “I enjoy spending time in the outdoors with my husband and two daughters. With my background and understanding of the integral nature of water as a key abiotic factor, I want to help preserve and improve the natural ecosystem of southwestern Connecticut.”

Kitsey Snow has served on the Board for more than a decade and organizes the Ridgefield Pollinator Pathway. She also serves on the Ridgefield Conservation Commission Board  where she helps to oversee the many miles of hiking trails for the RCC.  A resident of Ridgefield for over 25 years, she raised three sons and there, and was an active member of the PTA, serving in several positions.  She is a member of the Board of Directors for the Ridgefield Garden Club and enjoys hiking and kayaking.  She graduated from Wheaton College with a BA in psychology and worked in operations for Bankers Trust Co. in New York for seven years before moving to Connecticut.

Cathy Smith has lived in Wilton since 2002. She and her husband were initially attracted to Wilton and continue to reside there because of the enormous natural and historic beauty of the area. She joined NRWA in 2017 after volunteering to help clear invasives and plant native wildflowers and shrubs along the NRVT. She graduated with an MA from the University of Toronto and worked in advertising and financial services for many years. She now teaches yoga, gardens, and takes frequent hikes and walks in the woods throughout the Norwalk River watershed area.
