Meet the Staff at Barnstable Clean Water Coalition.


Zenas “Zee” Crocker

Executive Director

Executive Director Zenas “Zee” Crocker grew up on Cape Cod and has ancestral roots in Osterville, Cotuit, and Marstons Mills. Zee graduated from Barnstable High School and earned an Honors BA from McGill University in Quebec.

Before taking the helm at Three Bays Preservation, Inc., in April 2017, Zee spent over 30 years in the financial services industry in Boston where he specialized in Institutional Equities.

When he’s not working passionately on clean water issues, you can find Zee on Nantucket Sound where he’s a lifelong fisherman and sailor.


Heather D. Rockwell

Director of Operations

Heather is a native Cape Codder who grew up on the shores of Hyannis and received a BS in Biological Oceanography from the Florida Institute of Technology.  Her passion and career for all things aquatic began at the New Jersey Academy of Aquatic Sciences, the Whale Adoption Project, the Soundkeeper Program at the Alliance to Protect Nantucket Sound, and now at the Barnstable Clean Water Coalition.

Heather’s role as a delegate to the International Whaling Commission since 2000 has taken her around the globe to far flung places including Asia, Australia, South America, Europe and Africa. 

She lives in Marstons Mills with her family, husband Michael and sons Colin and Derek, who root for all things Boston Bruins.


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 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.


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.
