Amanda Barrett Wittman, Ph.D.

Consultant

As the kid of academics, I grew up in an environment where reading was the best way to get time alone and data could get me out of trouble. From that, my entire career has been about data-driven storytelling. Today, I am a learning design and evaluation expert who creates innovative curricula, designs program assessments, analyzes data and communicates findings to affect social change.

As a 20-year veteran of higher education and nonprofits, I have come to believe that wide and inclusive research design demands that we utilize non-colonial methodologies and facilitative leadership styles. I am especially excited about the possibilities of Ripple Effect Mapping for helping us answer questions like: How does my organization make meaning out of data? How might we leverage evaluation and strategic thinking to tell new and previously invisible stories? How do we remain asset-based and future-focused? These questions excite me and the organizations I work with. 

 My scholarly work examines the (im)possibilities of radical change agendas in organizations. Learnings about how change happens deepens my own facilitation and partnership work, and this perspective colors my consulting. We will learn together about the interactions of systems and individuals, action and inertia. 

Dr. Wittman received her Ph.D. from the University of Edinburgh in political science and international relations.

Sophia Cotraccia B.A.

Consulting Associate

As a Consulting Associate at Grant Street Consulting, I leverage my diverse background in humanities and management to deliver comprehensive analysis that drives client success. Drawing from my experience overseeing teams and projects, I provide strategic insights using mapping techniques to visually organize and analyze data.

I am a graduate of Oberlin College and Conservatory, where I developed expertise in storytelling, data visualization, and navigating complex topics with an analytical mindset. My academic focus on global religious traditions honed my ability to synthesize diverse perspectives and approach challenges with nuance – skills that prove invaluable in our client engagements.

My leadership experience also supports two Philadelphia-based percussion ensembles, where I provide musical leadership, support audience engagement initiatives and foster an inclusive environment. This combination of artistic discipline and team leadership enhances my collaborative approach at Grant Street Consulting.

With a unique blend of humanities expertise, management experience, and technical proficiency, I  am excited to continue supporting the innovative work of Grant Street Consulting.

Why “Grant Street?”

Why Grant Street Speech

I grew up on Grant Street in Utica, NY during the 70’s and early 80’s. Utica’s economy was suffering and the city was shrinking like many rustbelt cities of that era. My neighborhood was predominantly lower to middle income, and my neighbors and friends at school came from across the socio-economic spectrum. My mother worked with Southeast Asian refugees and my father was in the clergy, serving an economically diverse faith community. Creating environments where new and unexpected relationships could flourish was one of my parents’ many superpowers.

Inspired by my childhood experiences and my parents’ legacy, I have had the honor of developing and growing grant opportunities for many communities over the last two decades. At Grant Street Consulting, we’re excited to hear your stories, and to support the important work of building philanthropy and making an impact in your community.
