Meg A. Materne

Field Operations Manager

Meg grew up in Rhode Island and southeastern Massachusetts collecting sea shells and found the beginnings of her career niche in water quality at UMass Amherst where she graduated with a BS degree in Environmental Science.

These days, you can find Meg at the helm of our Boston Whaler where she undertakes water quality testing in ponds, rivers and embayments throughout the Town of Barnstable.  Before coming to the Barnstable Clean Water Coalition, Meg worked at the Broadmoor and Oak Knoll Sanctuaries owned and operated by the Massachusetts Audubon Society.

Meg resides on the Upper Cape where she takes a walk every day on the beach not far from her home.


Casey J. Chatelain

Special Projects Manager

A New York native, Casey grew up as one of those dreaded summer kids in Cotuit. After graduating from College of the Holy Cross with a BA in Environmental Studies, she moved to Cotuit full time to work for Barnstable Land Trust. A lifelong sailor and a former commodore of the Cotuit Mosquito Yacht Club, Casey’s love for the water (especially Cotuit Bay) drove her to get a Masters of Oceanography from the University of Rhode Island.

As if working for Barnstable Clean Water Coalition doesn’t get her on the water enough, Casey spends her time off work sailing, shellfishing, or paddling in her homemade kayak.


Christy Laidlaw

Development Consultant

Raised in Montclair, NJ, Christy spent every summer at her family's house in Harwich (yet another dreaded summer kid!). She developed her love of water from those Cape Cod summers, particularly swimming and hopping the waves.

Christy graduated from Skidmore College with a BS in Fine Art and after graduation moved down to NYC to work in the arts. She worked in art galleries and at an art school, and then in an unusual career twist, worked ten years as a Newsdesk Editor at Time Magazine. After relocating full time to the Cape with her husband and young daughter Claire in 2009, Christy worked for nearly 10 years at the Cahoon Museum of American Art in membership, public relations and development.

After watching the water quality decline on the Cape, she doesn't swim as much anymore and has become passionate about helping find a way to fix it.

In her free time Christy helps restore their historic home and enjoys walks on the beach with her family and their dog, Hoppy.

Jennifer Pic

Jennifer Loughran

Community Outreach and Engagement Consultant

Jennifer Loughran returned to her home state of Massachusetts in 2016 after living in Connecticut and Texas for more than 30 years. Vacationing every summer on Cape Cod and in Rhode Island, she always knew that living by the water would be “home” at some point and now resides in Cotuit. After graduating from Bryant University with a Bachelor of Science in Business Administration, Jennifer spent 20 years in various human resources and training and development leadership roles in the banking and insurance industries. In 2005, she retired from the corporate world and started down a new path working in the non-profit space, which led her to joining Barnstable Clean Water Coalition in 2019. In her free time, Jennifer enjoys volunteering for many worthwhile causes, hanging out at Oregon Beach on sunny days and traveling afar to new places.



Ian Walsh

Island Manager

Ian Walsh is the 2021 Seasonal Island Manager on Dead Neck Sampson’s Island (DNSI). He was born and raised in Minneapolis, MN. In 1907, his great-great-grandfather built a small cottage in Bourne, and Ian has spent summers there since he was a child.

An Eagle Scout, Ian has always had a passion for the outdoors, and graduated with a bachelor’s in environmental science from Iowa State in 2014. He has served with the Minnesota Conservation Corps, and most recently spent the summer of 2020 as an invasive species specialist working in the Black Hills of South Dakota for the National Park Service.

In the fall of 2020, Ian attended the National Park Service’s 14-week Law Enforcement Ranger Academy and became certified to work as a Law Enforcement officer in both Minnesota, and the National Parks. Though he understands the need for law enforcement, his interests lay more in public interaction and education, and he has managed to find that perfect balance on DNSI with BCWC.


Alex Ledwitch

Island Ranger

Alex is from Lake in the Hills, Illinois, where he graduated in 2020 from McHenry County College with an Associates in business, although his true passion is the outdoors. He developed his passion for nature through becoming an Eagle Scout and has spent hundreds of nights camping around the Midwest. Alex’s favorite outdoor recreational activity is either kayaking or archery. He decided to leave friends and family in Illinois to explore the beautiful East Coast and to pursue career and education opportunities and was thrilled to land a spot on the seasonal island staff.

When Alex is not on the island, you can find him exploring the Cape, at the library, or taking a hike. He splits his time between Falmouth and Stamford, CT.


Jonathan Rice

Island Ranger

Jonathan is from Fairhaven, MA and attended New Bedford Greater Regional Vocational Technical High School. He grew up travelling to and from Martha’s Vineyard on his family’s boat every weekend since he was 5 years old, so he has a lot of experience on the water, especially in Buzzards Bay.

Due to his upbringing, Jonathan knew from an incredibly young age that he wanted to pursue a career where he would spend much of his time outdoors and on the water. With that in mind, he is currently pursuing his bachelor’s degree in marine science, Safety and Environmental Protection at Massachusetts Maritime Academy. As for what Jonathan will do after he graduates, he is open to any opportunities that may present themselves. He has put much thought into careers involving environmental protection and was excited to join BCWC’s team working as a seasonal island ranger on Dead Neck Sampson’s Island this summer.

Jonathan’s experiences on the island have been invaluable, informing not only his growth as a person, but helping him better understand each side of the story, whether from the perspective of a conservationist or a local member of the community. When Jonathan is not working, you will most likely catch him running on the local bike path or fishing the surf on West Island in his hometown.


Bobby Skubal

Island Ranger

Bobby grew up in Minnesota, enjoying recreating on the many lakes and public lands that the state has to offer. Through this, he developed a strong appreciation for the natural world and its importance to our existence as a species. Robert graduated from the University of Minnesota in 2016 with B.S. in psychology, and a minor in neuroscience.

Since graduating, he has served three service terms through AmeriCorps programs. One with the National Civilian Community Corps (NCCC) in the southwestern U.S., and two with the Conservation Corps of Minnesota and Iowa. The 2021 summer season is Bobby’s first time on the Cape. He is excited to be part of a conservation effort in this unique ecological area, and to explore this region and see all that this natural environment has to offer.


David Carter

Island Steward

Growing up in Raynham, Massachusetts, David was never far from water or the coast. It was through this close connection to the ocean that he grew to love water and chose to attend the University of Maine (UM). A rising junior at UM, David is studying marine science with a concentration in oceanography. His research interests include the effects of polar ice caps on gyre and deep ocean trench circulation.

David hopes to pursue a career in research oceanography after graduation. He joined BCWC last year as the seasonal water sampling assistant and returned this year to work on Dead Neck Sampson’s Island as an island steward.  David enjoys assisting BCWC staff members with other projects. His interests include tennis, hiking and reading.


Lucy Pesek

Island Intern

Lucy has grown up swimming and sailing in the Three Bays. She is a rising junior at Northfield Mount Hermon, where she is an environmental leader on campus. Lucy has also worked on environmental issues and awareness with the Sunrise Movement in her home city of Boston. When she can't get to the waters of Cape Cod, she enjoys rowing crew on the Connecticut River.


Livia Graham

Water Sampling Assistant

Growing up on Cape Cod, being near the water and in nature was never uncommon for Livia. Through her appreciation of the ecosystems around her, she went on to attend the College of the Holy Cross in Worcester, MA, where she is completing a BA in biology. Livia’s interests include geology, ornithology, and freshwater ecology and she hopes to pursue a career in environmental science after graduation.

This summer, Livia is assisting BCWC with water quality monitoring, as well as helping with the cyanobacteria program at APCC. Her interests include birding, hiking, and spending time with friends and family.


Mackenzie Welch

Aquaculture/Water Quality Intern

Although Mackenzie moved around a lot growing up, one thing that remained consistent was spending every summer on Nantucket. Snorkeling and beachcombing on the island are what started her passion for marine life. At UMass Dartmouth, Mackenzie received a BS in biology.

She found her niche in marine shellfish working as a research assistant for the Maria Mitchell Association’s bay scallop research program.

But now Mackenzie has shifted her focus from bay scallops to eastern oysters in joining Barnstable Clean Water Coalition as an aquaculture intern. She is often at Hyannis Harbor maintaining the upweller tank, taking care of the oysters and educating the public about the biology of oysters and their importance to our local water quality and commercial fishery.


Nathaniel Horta

Aquaculture/Water Quality Intern

Nathaniel is a New Englander who grew up just off Cape Cod in Acushnet, where he enjoys exploring the lakes. Currently enrolled at the University of New Hampshire, Nathaniel is a rising senior working on his BS in Marine Biology. He is interested in conservation and educating people on ways to protect and improve our oceans and aquatic environments.

Most days, Nathaniel can be found down at Hyannis Harbor taking care of the oysters and upweller tank. Along with greeting and educating tourists and locals about BCWC’s oyster upweller project, he has grown quite fond of the baby oysters. On his days off, Nathaniel can be found fishing along the coast with friends and family.
