Senior Leadership


Rob Hazelton

Owner & Chief Executive Officer

Rob Hazelton founded D3G in 1994 as an environmental consulting firm. Early on he encountered an environmental process so difficult and convoluted, that few wanted to understand it. This was HUD! Rob dove headfirst into learning HUD, housing, tax credits, and leveraged finance. D3G steadily grew after expanding its services to include a myriad of housing preservation consulting. As population and social-economic issues expand, housing becomes more imperative than ever. Rob became a self-proclaimed Housing Geek, immersing himself and the entire company into affordable housing, public housing, senior housing, homelessness prevention, housing for the disabled, and most recently foster-care housing initiatives. Personal challenges and opportunities along the way, including being the parent of a special needs child, has enforced his feelings of empathy for others, which continues to translate daily in the work D3G does and the people the company serves. Rob gives a special thank you to all the housing advocates, housing geeks, and D3G clients out there, as we are all making a difference one unit at a time in this country.
