Senior Associates

A leader in Dattner Architects’ Sustainable Practice Group, David Levine AIA, LEED AP BD+C, CPHC was one of the firm’s first architects to achieve certification as a Certified Passive House Consultant.

Deeply interested in architecture’s manifestation at all scales, Mia Lee AIA approaches design holistically and is fascinated by the many ways in which the built environment is experienced.


Dedicated to socially responsible design, Jen Switala AIA believes that architecture evokes something different in each individual, and that this variety of experience creates a meaningful complexity to the urban realm.

Informed by his background as a musician, Adam Siegel AIA, LEED AP approaches design with the appreciation that a creative process involves many layers of complexity, rules, opportunities, and limitations.

Before studying architecture, John Seward AIA, LEED AP BD+C flew on C-17s in the Air Force for four years, experiencing the world and learning the value of discipline and collaboration.

Philippe Martelly AIA comes from a family of educators and is naturally adept at mentoring and team building, contributing to his belief that architects have a responsibility to the profession to help produce good architects.

As the Human Resources Director, Mary Beth Lardaro focuses on nurturing an equitable workplace culture that celebrates diversity, provides professional development opportunities for all employees, and supports the firm’s civic mission.


This year, William Stein FAIA transitions to Senior Consulting Principal. In this new role, Bill remains in a leadership position, engaged with projects, the firm, and with his professional associations, including serving on the board of the Citizens Housing Planning Council and chairing a NYC Code Revision Committee.

The evolution of Dattner Architects also includes the appointment of a Director and Resource Leader for each of our four studios. Rachel Ehrlich AIA, LEED AP BD+C; Keith Engel AIA, CHPD, LEED AP BD+C; Eric Epstein AIA, LEED AP; and Gia Mainiero AIA, LEED AP BD+C are serving as Studio Directors, overseeing practice areas. Our Studio Resource Leaders are Mia Lee AIA; Heather McKinstry AIA, LEED AP; Shefali Sanghvi LEED AP BD+C; and Adam Siegel AIA, LEED AP. Studio Directors and Studio Resource Leaders work together within and across the studios to promote the exchange of design ideas; to foster knowledge sharing; and to build community and culture.
