empowering transformation
people + places

We are catalysts of change, holistically developing shoreline communities and enhancing quality of life for a sustainable Great Lakes region. 


groundwork for sustainability

Karnerblue is a sustainable development consultancy specializing in public sector initiatives. We direct regions, cities and towns on how best to approach and navigate the complexities of urban redevelopment within the Midwest-Great Lakes region. Our successes in sustainability stem from our passion for transformation and uplifting places that people love.


As catalysts, Karnerblue perceives barriers to development as quality of life issues that can be mitigated or overcome through ecosystem integration. We lead clients through a catalytic process of change that brings disparate assets into renewed wholeness. By activating the deeper potentials of people and place, we help clients cultivate true capital and sustainable growth moving forward.

Our ideal clients are gamechanging public sector officials, staff and partners who desire a balanced, inclusive approach to developing the economy, environment and culture as one. Clients engage our firm early on because we bring a high level of integrity and expertise to major public infrastructure investments and special projects.

Founded by Tina Rongers in 2010, Karnerblue is an Indiana WBE/DBE firm, CDBG administrator and federal contractor.
