Boston Program Manager, Institute for Transportation & Development Policy (ITDP)

Charlie says: Being a part of LivableStreets helped me to understand why most cities are so car-oriented. I also realized that passionate citizens have the power to change that paradigm, making moving people the priority rather than vehicles.

Stephen Gershman / Internal Committee Chair
Principal Consultant, Arcadia Healthcare Solutions


Stephen.pngStephen knows that the easiest way for people to connect to the LivableStreets mission is experiential — each day people enjoy traveling along greenways and wonder the best way to cross a street and reach a friend's home safely — that's why he likes telling new friends about the organization while out on a group run, bike, or drive. Stephen looks forward to seeing LivableStreets develop a playbook and leadership structure that will enable everyone to advocate effectively for complete streets in their communities. As a member of the Governance Committee, Stephen helps with internal policy development and recruitment. He is currently a Senior Technical Manager at Arcadia Healthcare Solutions, where he builds technology for leading hospital networks to deliver better care to patients.

Vivian Ortiz


Vivian-Ortiz.pngVivian grew up in El Paso, TX and is a resident of Boston's Mattapan neighborhood. You can find her spreading the word about great things in Mattapan on twitter @mattapanviv. She says she joined the LivableStreets board because the organization has been a “one-stop transit advocacy shop” for her, and she hopes to bring the Street Ambassador program to Mattapan and surrounding neighborhoods. Vivian was a featured speaker at the StreetTalk 10-in-1 in 2015, and fondly remembers Boston Chief of Streets Chris Osgood running over to introduce himself right after she’d just finished pointing out the eight lanes of traffic that people were forced to cross without a crosswalk on Blue Hill Avenue in Mattapan Square (An area which still has yet to see any changes!). Vivian is Coordinator for the Let's Get Healthy, Boston! project for Mattapan Food and Fitness Coalition in conjunction with the Boston Alliance for Community Health and the Boston Public Health Commission. She enjoys jigsaw puzzles and playing board games.

Since then, the organization has engaged thousands of people who want to live in a city that they can be proud of, one that is designed around people rather than automobiles.

Emily Warren

Kathryn.pngEmily grew up in the auto-oriented suburbs of the San Francisco Bay Area, but is now delighted to live car-free in Somerville. An avid pedestrian, bike commuter, and recreational cyclist, she is passionate about expanding complete street infrastructure and multi-use paths throughout the region to support active transportation. Emily currently serves as a Venture Partner at Fontinalis Partners, a venture capital firm focused exclusively on investments in the transportation sector. Previously, she was one of the original employees at Lyft, where she lead the company’s transportation policy team for several years, and at Lime, where she built the global policy and public affairs team from the ground up. She believes new mobility technologies can play an indispensable role in reducing reliance on car ownership - provided the right policies are in place to prioritize the public interest. When she’s not caught up in wonky debates about mobility datasharing policy, running speed intervals around the Ellis Oval, or making a fool of herself at improv class, Emily can often be found walking her two beloved rescue dogs, Leo and Charlie, along the Somerville Community Path.
