Our Services

GSI’s services are characterized by their breadth and depth. We are a full-service firm, offering expertise in strategic planning, campaign management, major gifts and grants, board and staff development, research and analysis, and communications and marketing. Our depth is reflected not only in our extensive experience but also by the extent to which we partner with our clients. We don’t just counsel—we roll up our sleeves and help get the job done.

We know your organization is unique. Your culture is unique. Your challenges are unique. Through our deep engagement, we’ll get to know you well—your staff, volunteers, donors and prospects—and customize our services based on your particular needs. There are no shortcuts, no cookie-cutter solutions to help you achieve your goals.

Planning Studies

GSI’s approach to campaign planning has revolutionized the way our clients prepare for a capital campaign. Historically, organizations have engaged fundraising counsel to conduct a feasibility study, testing the “possibility” of a campaign. Realizing that for most of today’s clients a campaign is a must, we have taken the campaign study process a giant step further by introducing a comprehensive campaign planning phase to the effort.  In brief, this phase emphasizes quantitative data analysis supplemented with qualitative research facilitating remarkable accuracy in projecting philanthropic potential and goal setting. The result: Capital campaigns that consistently exceed goal.

Capital and Comprehensive Campaigns

GSI’s core competency is planning and managing capital and comprehensive campaigns. Each campaign is tailored to the client’s unique circumstances ensuring the effort is conducted according to their way of doing business. We offer a range of service options including full or part-time onsite campaign management, of-counsel service or remote engagements – or a combination of these. We are flexible and work with clients to devise an effective, efficient service plan reflecting organizational culture and budgetary considerations.  Very importantly, GSI’s Calculation of Potential – our proprietary methodology for projecting philanthropic potential and tracking funds raised in real time – produces realistic financial parameters which set the foundation for accurate goal setting and, ultimately, successful campaigns.

Strategic Philanthropic Program Consultation

Customized for each client, consultation services emphasize the essential components of building and sustaining a dynamic fundraising enterprise, including strategic planning, staff and leadership development, volunteer training, program audits, and philanthropic capacity assessments—all to prepare your organization for better fundraising results.
