Our company founder, H.H. Henningson, noted over a century ago, “There is always time enough for kindness.” Founded in 2012 by HDR Chairman and CEO Eric Keen, the HDR Foundation is an extension of that mission, aiming to benefit the communities in which we live and work.

The HDR Foundation provides grants to qualified organizations that align with HDR’s areas of expertise: education, healthy communities and environmental stewardship. As an employee-funded and employee-driven foundation, preference is given to organizations located in communities where HDR employees live and work, and those with strong employee involvement. Since its inception, the HDR Foundation has provided nearly $5 million in grants to over 200 organizations.
