Nantucket Maria Mitchell Association Announces New Executive Director – Joanna Roche

Kelly Bernatzky • July 28, 2021

Helene Weld, the President of the Board of Directors of the Nantucket Maria Mitchell Association (MMA), announced today that Joanna Roche will take on the role of MMA’s next Executive Director. According to Weld, “While our search allowed us to consider a number of excellent candidates from across the country, we are pleased to welcome a Nantucket resident to this critical role. We are certain Joanna is the person to take our organization to the next level in achieving our mission: to create opportunities for all to develop a life-long passion for science through education, research, and first-hand exploration of the sky, land, and sea of Nantucket Island.”

 

Joanna is a proven leader who has extensive experience in both the nonprofit and business world. In her past roles, she has led large teams, worked successfully with diverse boards, delivered strong financial performance, increased and strengthened revenue streams, and focused on providing exceptional guest experiences. Her past career successes will serve her well in carrying out the goals of the MMA.

 

Joanna has articulated a bold vision for the future and for what can be next for the organization, including raising the visibility of MMA not only on the island but nationally; enhancing the overall experience for those visiting and interacting with MMA; and building and diversifying the funding streams for the organization.

 

Joanna said, “I’m especially enthusiastic about using my passion to help continue to promote the legacy of Maria Mitchell. Mitchell was a true pioneer, not only as a woman scientist, but as a woman leader who was far ahead of her time in advocating for and supporting the next generation of the curious, and those who love nature and learning.”

 

She has a well-established network of connections on the island and has served on the Town of Nantucket Finance Committee for the past six years. She was also recently named to the Coastal Resiliency Advisory Committee, where she will advocate for and contribute her expertise on issues of importance to both the island and the MMA.

 

She was most recently the Executive Director of GSN Planet and Foundation, where she led two global nonprofits focused on sustainability and education in the wellness arena. She has consulted on numerous new capital and development projects, managing budgets, financial oversight, and revenue growth. She also served as an executive at the Westmoor Club where she led the vision, revenue growth, and staff of the Club’s Wellness Center. Earlier in her career, she was Executive Vice President and Chief Creative Strategist for Pierce Mattie Public Relations in New York.

 

Frances Symes, who serves on the MMA Board and co-chaired the search committee, said, “MMA is pleased and excited to have the talents and energy of Joanna as our new leader. With her understanding of the island combined with her passion for the environment, business expertise and commitment to a high-quality visitor experience, we know MMA’s future is in good hands.”

 

Originally from the Berkshires, in western Massachusetts, Joanna has always been active in the communities where she has lived, serving on many local boards and committees. She is also a well-known speaker, hosted a long-running radio show here on Nantucket, and is a wellness and meditation teacher. Roche loves the outdoors, and is a longtime runner. 

 

Weld concludes, “This is an exciting time for MMA, as we look to the future and find new ways to grow our impact and presence both here on Nantucket and nationally. Having Joanna as Executive Director will make us that much more successful in leading the organization into a strong and vibrant future. We are grateful to Interim Director Jason Bridges for skillfully leading the Maria Mitchell Association over the past year.”

 

The Maria Mitchell Association is a private non-profit organization. Founded in 1902, the MMA works to preserve the legacy of Nantucket native astronomer, naturalist, librarian, and educator, Maria Mitchell. The Maria Mitchell Association operates two observatories, a natural science museum, an aquarium, a research center, and preserves the historic birthplace of Maria Mitchell. A wide variety of science and history-related programming is offered throughout the year for people of all ages.

Being Nantucket, we tend to stay cooler than the mainland in the summer though the humidity is often over the top. It often makes me think about people in the nineteenth century and earlier – heck, even well into the mid 1900s, and how they handled the weather. With climate change, we have warmed and our weather is more severe and volatile at times. Instead of a nice gentle rain, we get a deluge and the ground has trouble absorbing that sort of onslaught. But they did did still have heat and humidity – and think of a fire in the hearth all day and the bake oven – if it was a baking day. And now, think of the women standing in front of the firebox and bake oven, or even a cook stove later on. I am sure if the confines of their home, alone, les could be worn but for the most part, those women still had a lot of layers on. I am sure that a cloth dipped into or run under the mouth of the pump and wrung out gently – to keep as much as the cool, moisture as possible – was tied around a neck or stuffed down a dress front (or even in addition to the wet neckerchief).  At the Mitchell House, we get a little of the feeling for this. We have no HVAC in the House so we rely on doors being open – with screens to keep the bugs out – and the roofwalk opened (also with a screen) so that air circulates throughout the House. Air can move nicely through – the heat rises, the air moves up and out of the roofwalk hatch very much as it might have in Maria Mitchell’s day. While we do not have the added (somewhat) drying benefit of the heat of the fire in the kitchen, we do have all of the original horsehair plaster, so the House does remain somewhat cooler and drier overall. But some days, the relative humidity does get up into the 90s in the House – that’s when I say, “Get out your umbrellas!” JNLF

NANTUCKET, MA— The Maria Mitchell Association’s (MMA’s) Nantucket Harbor water-quality monitoring buoy is now part of the Northeastern Regional Association of Coastal Ocean Observing Systems, known as NERACOOS. NERACOOS is one of eleven regional associations that make up the U.S. Integrated Ocean Observing System, or IOOS, NOAA’s national ocean-observing network for gathering and sharing ocean, coastal, and Great Lakes data. This connection means that real-time data from Nantucket Harbor are no longer held only within a local monitoring program. They are now available through the NERACOOS Mariners Dashboard, where scientists, resource managers, educators, mariners, and the public can view Nantucket Harbor conditions alongside other coastal observing sites from Long Island Sound through the Gulf of Maine. The monitoring buoy carries a suite of sensors that track changing conditions such as temperature, oxygen, acidity, nutrients, and underwater light. These measurements show what eelgrass, bay scallops, and other marine organisms are actually experiencing over time. “This is an important step because Nantucket Harbor is now part of a larger coastal observing system,” said Dr. Betsy Sherman, the Maria Mitchell Association’s Senior Marine Science Advisor. “Our data can be compared with data from other sites, used in regional analyses, and placed in a broader environmental context. We are not just looking at Nantucket Harbor in isolation.” The Nantucket Harbor buoy project has been supported by the Great Harbor Yacht Club Foundation, whose early investment helped make continuous water-quality monitoring in Nantucket Harbor possible. Additional support has been provided by the Remain Nantucket Fund at the Community Foundation for Nantucket, the Osceola Foundation, the Sociable Weaver Foundation, and through collaboration with the Town of Nantucket Harbormaster. The timing is especially relevant for coastal communities because NERACOOS is also leading the newly funded NSF Seafood Engine in New England, a regional effort focused on strengthening fisheries, aquaculture, seafood technology, and coastal economies. For an island community facing changes in water quality, habitat, fisheries, and climate, joining this regional network strengthens the scientific foundation for understanding and protecting Nantucket Harbor. The Maria Mitchell Association was founded in 1902 to preserve the legacy of Nantucket native astronomer, naturalist, librarian, and educator, Maria Mitchell. After she discovered a comet in 1847, Mitchell’s international fame led to many achievements and awards, including an appointment as the first professor of astronomy at Vassar College. Maria Mitchell believed in “learning by doing” and today that philosophy is reflected in the MMA’s mission statement, programs, research projects, and other activities. The Maria Mitchell Association operates two observatories, a natural science museum, an aquarium, a research center, and preserves the historic birthplace of Maria Mitchell. A wide variety of science and history-related programming is offered throughout the year for people of all ages.  ####

Finished. Finis. Completed. Done. Accomplished. The Mitchell House roofwalk is now done. Back to looking a bit more normal up on the ridgeline. But as I may have noted in the other post about the roofwalk, the one that was removed due to its condition and how it sat on the roof’s ridge was far from the original – or even a nineteenth century one. I am including an image from about 1908 or so in order for you to see the Mitchell House without a walk – even then. Now, an interesting fact is that I am able to date the undated photo because in the west image – where you see the open year – you can actually see the shadow of the Maria Mitchell Vestal Street Observatory – at the backside of the 1825 Kitchen. And given that shadow you also know its late afternoon since that side of the House, as noted, faces West. Another interesting feature is the long downspout – more like a side spout – that takes water from the front gutter, along the upper West façade of the House and across a window and then over the 1825 Kitchen roof where it terminated in a cistern – still in existence under the ground today.
