environmental planner

The Horsley Witten Group is thrilled to announce that Gabriella Spitzer has joined our growing team at the Boston, MA office. Gabriella’s area of expertise and focus is climate change and resilience planning. We are excited to include them on a wide range of technical and community engagement projects.

Growing up in Sharon, MA, Gabriella learned about the connections between social justice, public health, and the environment from their experience working for an organization called The Food Project. The group focuses on youth development and racial justice through urban and suburban farming. These early experiences were formative: Gabriella’s environmental approach has always focused on how environmental issues—especially land use—relate to all other kinds of other social issues.

Gabriella earned a Bachelor of Arts Degree in Environmental Science at Barnard College/Columbia University in New York City and a Master of Science in Environmental Science with a concentration in planning and management at the University of Illinois in Springfield. While working for the New York State Department of Agriculture and Markets they developed a program to help farmers reduce their greenhouse gas emissions and become more resilient to the changing climate. New York’s Climate Resilient Farming program is still going strong! Gabriella then worked as a consultant for FEMA helping the agency assist communities with reducing risks and becoming more resilient to climate change. Gabriella is excited to bring their years of experience in climate change resilience, hazard mitigation, climate policy, and environmental planning to HW.

Gabriella is an artist and, when they are not busy with work, enjoys painting with acrylics on canvas,  silk paints on silk, watercolors on paper, and combining them in mixed media in a new basement studio space. They developed a Haggadah for Passover called Haggadah Min HaMeitzar, A Seder Journey to Liberation published by Ben Yehuda Press. It includes a traditional text along with several kinds of commentary, including an environmental commentary, that Gabriella developed. The Haggadah features their art as well. Their next project involves art and essays on Jewish text and climate change.  

Welcome to HW, Gabriella!

Senior Engineer

The Horsley Witten Group is proud to announce that Alex Cedrone, Senior Engineer, has joined our engineering team in Exeter, NH.

A Groton, Massachusetts native, Alex grew up with an engineer parent who encouraged him to seek out career options in engineering. His love of history propelled him to a college experience centered around engineering and law with the environment  a close second. Alex loves green stormwater infrastructure and design and favors best practices for the site where possible. He has relevant experience with site work, remediation, and water treatment, along with research, zoning, site design, and soil evaluation.

Alex earned his Bachelor of Science Degree in Civil and Environmental Engineering with a Minor in Political Science at the University of Massachusetts, Amherst and his J.D. from the Mass. School of Law. At HW, he has hit the ground running with peer reviews and school site design projects.

When he is not working Alex enjoys spending time with his wife and Milo a four-year-old Australian Shepherd  who lives for frequent long walks and hiking adventures. Alex likes to spend free time on Cape Cod, enjoys skiing, and basically spends as much time outside as possible. *Hint, he owns an Aussie! Alex is a sports fan and especially likes hockey, lacrosse, and football plus horror and comedy movies. We are glad you have joined our team. Welcome to HW, Alex!

Senior Associate

The Horsley Witten Group is excited to share that Gary Hedman has rejoined the company in the role of Senior Associate! Gary’s career spans 24 years, with experience in site assessment and remediation, contaminated materials management, sediment characterization in support of ecological restoration projects, and assisting clients in complying with local, state, and federal regulatory programs.

After 12+ years with Horsley Witten, Gary spent the last 7 years at a leading New England based engineering/consulting firm helping them to grow their Eastern MA site assessment and remediation team and contributing to their emergency response, contaminated soils management, and sites management practice. He has learned over the years that collaboration across parties and honest communication are key to building meaningful client relationships and ensuring successful project outcomes.

A life-long New Englander, Gary earned his Bachelor of Science Degree in Environmental Studies at the University of Vermont. Encouraged from an early age to take a hands-on approach to problem solving, there’s nothing he loves more than figuring out a fix or finding a new hack. His roots in Vermont and on Cape Cod drive a strong sense of appreciation and love of the outdoors. Gary is excited to come back to Horsley Witten Group and to see so many familiar faces who are mission driven and committed to nature-based solutions. Gary is “off and running” on new projects and contributing to ongoing efforts. His passion for ecological restoration along with strong project management skills will benefit our clients and partners.

When Gary is not working, he’s most likely starting a new renovation or repair project around the house or lending a hand to friends and family, but his lifelong passion is skiing. He believes in “giving back” and is a dedicated member of the Magic Mountain Ski Patrol (his better half, Stacey, is also a Patroller). He volunteers with the Londonderry Vermont Conservation Commission and Village Wastewater Committee. Stacey (a 7^th generation Cape Cod native) and Gary are grateful to call both Vermont and Cape Cod home and share it with her 12-year-old yellow bellied mutt from Louisiana, Cajun! Welcome back to HW, Gary!
