For years, consultants Nanette Fridman and Kelly Segal have collaborated with each other—and other trusted colleagues—to develop solutions to their clients’ varied organizational challenges. Over time, they found themselves explaining this working model over and over again. So once again they put their heads together and, after many hours of brainstorming, they launched Effect Collective.

Effect Collective is a consulting, training, facilitation, and coaching firm that specializes in helping both nonprofit and corporate leaders and team members do the work that matters most.

Through Effect Collective, Nanette and Kelly’s past, current, and future clients receive the same excellence, accessibility, partnership, and ease of collaboration as always—plus they have access to a new group of curated, trusted experts.

Nanette Fridman is a catalyst for values-driven organizations and leaders. 

Before launching Effect Collective, Nanette founded and led Fridman Strategies, Inc. for nearly 20 years. During that time, she helped leaders across North America—from small start-ups to large international organizations—plan for success, solve big challenges, advance their missions, and maximize their impact. Known for her good humor and high energy, Nanette is a frequent keynote speaker, workshop presenter, trainer, and facilitator. She is the author of Holding the Gavel: What Nonprofit Board Leaders Need to Know and On Board: What Current and Aspiring Board Members Must Know About Nonprofits & Board Service.

Nanette is honored to be a Harry S. Truman Scholar. Nanette has held many volunteer leadership roles in the greater Boston community and beyond. She lives in Newton, Massachusetts, with her husband and two children.

Kelly Segal

Specialties: Nonprofit Management, Coaching, Organizational & Systems Optimization, Fundraising

Kelly Segal raises the bar for mission-driven organizations, elevating performance to reach new heights.

With 25 years of experience working in the trenches alongside nonprofit and educational institution leaders, Kelly is a lightning-quick diagnostician—one who offers practical solutions to today’s management, fundraising, and communications challenges. Kelly's work is fueled by the idea that the strength of communities rests on the shoulders of healthy, values-driven organizations. As she develops results-driven strategies for strength maintenance and impact-maximizing growth, Kelly makes a point to consider an organization’s culture and bandwidth. She gets particular joy from managing professional teams and facilitating skillful leadership transitions. Kelly’s coachees describe her as their “secret weapon” and “a warm kick in the pants.” And as a collaborator by nature, she began working with Nanette Fridman in 2019 to offer more comprehensive services to clients. Before joining forces with Nanette to launch Effect Collective, Kelly founded and ran a nonprofit management consulting firm for 13 years and served as interim-executive director for several clients. In these roles, she leveraged methods to activate leadership, energize professionals, and increase efficiency and combined different operational and management philosophies to quickly assess systems, diagnose problems, design strategy, and execute solutions. Originally from Colorado, Kelly graduated summa cum laude from Brandeis University with degrees in English, art history, and women’s & gender studies. She is also a recipient of the J.V. Cunningham Award for Excellence in Writing. Throughout her career Kelly, has served on a variety of boards for organizations dedicated to racial justice, women's rights, and educational equity. Kelly lives in Wellesley, Massachusetts, with her husband and two sons. She loves travel (except to or from soccer matches), late-night research (preferably Page 6), cooking, and audiobooks of all kinds.

Once Nanette and Kelly get to work, if you have additional needs, they activate the Effect Collective to find your perfect match of professional partners. The Collective features 12+ Members who are long-time trusted partners and experts in their fields, and in addition to Effect Collective’s core services, these Members provide:
