Susan Eastwood has been a member of Sierra Club CT for many years. She serves on the Political Committee and is proud to have been endorsed by Sierra Club in her run for the state legislature.

Susan has lived in Ashford with her husband, Tony, for the past 25 years. Susan has been a tireless advocate here in Connecticut for over 30 years.  She founded and Chairs the Ashford Clean Energy Task Force and served on the Planning and Zoning Commission and the Board of Finance. Her main focus now is fighting to slow the impacts of climate change, which she believes to be the overarching threat that we and future generations face.
We are seeing the devastating results of our dependence on fossil fuels right now! This has brought her to fight against the new fracked gas power plant recently approved in Killingly and to oppose expansion of the toxic ash landfill in Putnam..

Angel Serrano

Term: 2022-2023


Angel Serrano is a Community Organizer at Connecticut Citizen Action Group (CCAG). He is graduate of Goodwin College with a degree in Environmental Studies with a concentration in Environmental Health and a minor in Business. He is passionate about his education and hopes to apply the knowledge he gains into advocating for policies to support the sustainability movement. 


Angel has a strong interest in politics, and its effects on society. He plans to pursue a Masters in Public Policy, and combine knowledge of the law and the environment in order to fight for the transformation of our communities and businesses into sustainable ones.


He is an experienced citizen lobbyist and has engaged in legislative advocacy with the Legislative Team. Angel can bring legislative savvy, environmental knowledge and friendly relationships with Hartford politicians to the Connecticut Chapter.

Jeff Gross
ExComm Member
Term: 2022-2023

Jeff Gross is a life-long adherent to sustainable living practices, but only found Sierra Club in 2016, when he volunteered to lead the new program now known as Clean Transportation for All.   As is the case with some of the Sierra Club priorities, including wind and solar energy, the Transportation's campaign work at the levels of legislation and public awareness is being reinforced by market forces:  in spite of outright hostility from the current US administration, all of these cleaner technologies are experiencing high growth and are projected to dominate in the coming decades.


As an Excomm board member, Jeff would like to engage in advocacy for a broader range of Sierra Club initiatives, including the  Ready for 100 Campaign and Outings. The hope is that these programs focused on local towns and local attractions, will bring in more active Volunteers, including our substantial base of Connecticut Sierra Club members.

Susan Petit
Shoreline Group Representative

For the last few years I have served on the Sierra Club Shoreline ExCom and the Connecticut Chapter Political Committee, on the latter helping to conduct interviews for candidates looking for endorsement.  Involvement with the Political Committee has been significant to me, especially so in this time of political chaos and unrest.  I have also been fortunate to have been able to travel back and forth to Africa these last years, meeting with researchers and working on wildlife conservation projects.  I hope to do more in this area.  Another passion of mine is wildlife photography, both here and in Africa.  

Arthur Helmus
Legislative Chair and ExComm Member
Term: 2023-2024

Arthur is a lawyer and currently develops commercial, industrial and residential solar power projects in four states. Prior to that, he served as a 2nd Vice President in the insurance industry and as corporate counsel where he led teams responsible for remediating hundreds of pollution sites across the United States. Art has served as a member of the CT Chapter Sierra Club Legislative Committee for the past year and currently serves as Vice Chair. As a renewable energy professional and legislative activist, Art has lobbied the Connecticut Legislature, submitted expert testimony on behalf of the Chapter, and has given presentations to industry groups on the need to improve the collaborative relationship between industry and environmentalists. He seeks to apply his skills earned through his MBA and Masters Degree in Sustainability and Environmental Management to enhance the effectiveness of the Sierra Club's initiatives. Art's knowledge and background will contribute significantly to the Chapter's brain trust.  

Roxanne O'Sullivan
ExComm Member, CCL Delegate, Communications Committee
Term: 2023-2024

I joined the Connecticut Sierra Club Communications Committee in 2017. Since then, I primarily work on communications for the Chapter, including the website, social media and the newsletter, and have also been involved in data base development. I support the work of the Chapter Director by helping with social media and other tasks. I feel working on the website provides the best opportunity for my skills and talents to benefit the Chapter. I'm a millennial, a digital native, and am deeply committed to the Sierra Club mission. I'm very eager to join the ExCom this coming year! When not working for the Sierra Club, I work full time as a Registered Nurse. In my free time I enjoy the outdoors by biking and hiking.

John Pilgrim
ExComm Member
Term: 2023-2024

Backcountry camping devotee turned environmentalist, John meshes a passion for data with the outdoors. He discovered the Sierra Club in 2020 after driving after wedge between himself and most of his friends and family over sustained discussion of environmental inadequacy. What John lacks in experience he makes up for in his fervent and detail oriented nature.


Since finding his family, John has been involved in various initiatives such as air quality research while supporting core IT tenets of the club through the Communications team. He intends to expand out into the strategic side of the club by getting involved in the CT Executive Committee. When he’s not out hugging trees, John can be found throughout Hartford country driving the speed limit on his growing collection of electric PEVs.

Stephen Lewis
Chair of the Hartford Group

Steve Lewis is an avid environmentalist who gained his appreciation for nature and conservation as a Boy Scout and has carried that passion on into adulthood.  As a Scouting leader, he was awarded a significant conservation award for his work on monarch butterfly conservation.  Along the way he also became a Leave No Trace Master Educator and teaches Outdoor Ethics which are rooted in Aldo Leopold’s land ethic. 

In addition to his Scouting involvement, Steve is a Connecticut Audubon Master Naturalist who loves birding and teaches naturalist history and climate change in their Master Naturalist program in multiple Connecticut Audubon locations. 

Steve worked in the Connecticut General Assembly for over a decade and brings his policy and legislative process experience to the CT Sierra Club Legislative Committee. He has extensive experience in public health and environmental health policy and has worked on mitigating such environmental injustice as lead poisoning, asthma, and the impacts of landfills and waste burning in urban neighborhoods.

As an active champion of electric vehicle adoption, Steve helped South Windsor host its first Drive Electric Week event. He also worked with the town on model EV charger zoning regulations.  His work with the town on behalf of the Sierra Club helped the town earn Sustainable CT Silver Status.

In 2021, Steve agreed to become chair of the Connecticut Sierra Club Hartford Group and hopes to help that team achieve its environmental goals. He strongly believes in the power of collective action which is well summarized in the quote by Margaret Mead, “Never doubt that a small group of thoughtful, committed citizens can change the world: Indeed, it’s the only thing that ever has.”​

Tanya Bourgoin
Wildlife Committee Chair

Tanya was born and bred in CT and is a lifelong resident of the state, with the exception of a few years spent in Colorado attending Colorado State University. She started her first conservation advocacy organization back in elementary school. After receiving a pin maker for Christmas, she recruited her friends to form a group to sell the pins, baked goods and branded pencils and donated the proceeds to national wildlife causes. In high school, she and a few close friends founded a school-wide organization to promote diversity, tolerance and inclusion long before most people were thinking about such issues. At the age of 6, she helped her grandmother raise an orphaned baby squirrel, and in 1998 she attained her wildlife rehabilitation certification.

Tanya is the President of the Friends of Machimoodus and Sunrise State Parks which she co-founded in 2016. In September of 2022, she was proud to be elected to the board of Friends of CT State Parks. Most recently she was appointed to serve on her town's Sustainability Team, a role which will allow her to share her knowledge and opinions about our natural resources and how to protect them. Additionally, she has been a DJ on WCNI Radio, a non-commercial listener-supported station in New London for the past 15 years, serving as the fundraising director from 2015 until this past March. When she’s not in a meeting, she likes to be outdoors with her husband, dogs, ducks and goats.

I am ready for 100.

Shawn Gregory
ExComm Member
Term: 2023-2024

Shawn Gregory is a senior at Wilton High School in Wilton, CT.  He became interested in environmental work after conducting research on the effects of PFAs contamination on mature stem cells at Yale University.  After encountering the potential risks of these chemicals through his findings, Shawn began to work with a variety of local organizations like Wilton Go Green and the Norwalk River Watershed Association to fight for overall environmental change.  Examples of his efforts include preventing the expansion of a methane gas pipeline and successfully protesting the installment of a new turf field at a local, all-natural meadow.  Shawn has also founded his own organization, named "Rhysos," to increase environmental justice coverage in secondary school education.

As an ExCom board member, Shawn will support anti-PFAs legislation and advocate for the protection of underserved communities from further environmental devastation.  He would also like to create a CT youth environmental network to bring together Connecticut youth in the fight for meaningful environmental change.
