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.

Jennifer Picre

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.

Lillie Peterson-Wirtanen

Communications Coordinator

Lillie grew up moving between the east and west coast, always ready to explore the nearest beach. Protecting the environment for the benefit of people and wildlife has always been close to her heart. After graduating with an Honors BA in Classics from University of California, Santa Barbara, Lillie returned to the Cape to start a career working in environmental nonprofits.

Lillie currently works with Barnstable Clean Water Coalition and Barnstable Land Trust, contracting with other local nonprofits and small businesses. When she isn't working, Lillie loves exploring local beaches and conservation areas with friends, family, or her dog Red.
