Founder, president and owner, Carol Gretter is responsible for the successful day-to-day operation of the Eleven of Eleven team.

Known for her solution-oriented approach, Carol brings over 20 years of in-depth project experience to her work. She has a background in large-scale complex projects: land development, site analysis, and multi-use educational buildings, as well as intimate detail-oriented designs, specialty classrooms, performance spaces, and offices.

She has written curriculum and provided training for K-12 teachers in addition to architecture and design professionals. The combination of being a practicing architect and teaching in a variety of public and private classrooms, gives Carol unique insights when designing learning environments for schools and institutions.

In addition to her professional experience in commercial, residential, institutional, and urban design, Caroline helped construct a school in the Himalayas while studying abroad in India. She’s maintained her relationship with academia as an adjunct professor at the New York Institute of Technology, where she teaches students about traditional architectural graphic standards and how to produce modern construction drawings using Revit.

Caroline holds a Master of Architecture from the University of Texas at Austin and a Bachelor of Urban and Environmental Planning from the University of Virginia. She is a registered architect licensed in New York.
