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.

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. Dannhauser

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.


Emma Taccardi

Emma Taccardi

Water Steward

Emma Taccardi grew up in Rochester, NY and earned her BA in biology at Hamilton College. After graduating, she worked for The Nature Conservancy on Block Island, RI and the Lawrence Berkeley National Laboratory in Berkeley, CA. She recently graduated with her PhD in marine biology at the University of Maine. Outside of work, Emma enjoys playing guitar and piano, running, and reading. She is excited to work for BCWC because she is learning about estuarine ecology around the Cape and gaining experience operating boats. In the future, Emma plans on exploring marine policy and the connection between science and its implementation.
