As National Sustainable Design Leader at HED, Daniel steers a team promoting high-performance design across the 450-person firm.  He is a member of the AIA LFRT and Building Green Sustainable Design Leaders network as well as the 2030 National working group.

Before being promoted to National Sustainable Design leader, Daniel led a production team in the Higher Education and Healthcare studios as a Senior Project Architect leveraging almost 20 years of experience.  His direct knowledge of the practice greatly informs his efficacy as a sustainable design leader. 

Prior to HED, Daniel practiced at smaller firms gaining a diversity of experiences, guiding projects from the formative stages through closeout.  He shepherded various high-performance design projects, including the first LEED Gold-certified building in Westchester County, NY and worked for industry expert Randolph Croxton, authoring major portions of the Sustainable Design Guidelines that governed the redevelopment at the World Trade Center site.  Prior to practice, at RPI’s School of Architecture, Daniel completed both under-graduate and Post-Professional Master’s Theses on new technologies for intelligent and adaptive buildings and advanced façades and taught building science as a teaching assistant in RPI’s core architectural program.
