Gladiator Consulting

Gladiator Consulting partners with nonprofit organizations to embrace an abundance mindset.  We believe in an abundance of time, opportunity, talent and resources for each of our clients and those they serve.  We acknowledge a troublesome gap between available resources and how they are used/shared. We are compelled to find clarity around how our client’s mission and programs fit into the larger nonprofit ecosystem and we work internally, externally and collaboratively to serve the broader community. 

Since 2015, Gladiator Consulting has partnered with over 30 nonprofit organizations to reimagine planning, strategy, fund development and communications. The majority of our clients serve children, low-to-moderate income families, distressed communities and those impacted by inequitable policy. We seek to partner with organizations who share our desire to create equity throughout our region. We have created and supported implementation of strategies that build strong organizational culture with shared priorities.  Our approach to organizational culture and team building creates a shared mindset of abundance and collaboration across work teams, organizations and systems. We understand the interconnected nature of fund development, communications and advocacy and work alongside our clients help them transcend mission to achieve vision.
