Zhanina Boyadzhieva, AIA

My passion is the relationship between cultural concepts and physical contexts. Architecture is a reflection of a culture at a given time but it is also a powerful tool for reshaping future social patterns and beliefs. It can heal, provoke, question, stimulate, inspire, and transform.

Lucy Hawkins

Good design is creative and rigorous; seeking to imagine spaces that promote health for each person, our communities, and the planet.

Yoojung Hyun

Design always focuses on improving people’s lives beyond the present. I believe design possesses the power to enhance human experiences and quality of life, going beyond mere form and function. I aim to offer a better environment for individuals by utilizing the influence of space through design. I see architecture not just as a building but as a space where people live, feel emotions, and interact. Therefore, I believe well-designed architecture can provide people with a more abundant, comfortable, and meaningful experience.

Ethan Jen

Architectural design is the silent composer of spaces, orchestrating elements to create a symphony of functionality and visual allure.

Danica Kane, AIA
Maryam Karime, Associate AIA

I am driven by the process of creating a holistic and compelling vision in response to the forces that affect good design, which is thereby thoughtful, empowering and transformative. It has the ability to impact and shape the lives of people well beyond our lifetime

Andrea P. Leers, FAIA

Dedicated to seeking cross-cultural connections, Andrea is an internationally recognized leader in urban and campus design, and building for higher education. A pioneer in timber design and construction for academic settings, she led a design collaborative to realize the largest cross-laminated timber (CLT) building in the United States—Adohi Hall at the University of Arkansas, which received a 2021 AIA Housing Award—and was principal on the John W. Olver Building at the University of Massachusetts Amherst, which received a 2020 AIA COTE Top Ten Award.

Andrea’s approach to architecture was shaped by her Masters of Architecture studies at the University of Pennsylvania’s Graduate School of Fine Arts, then led by Louis I. Kahn, pursuant to an undergraduate degree from Wellesley College. A subsequent year in Japan as an NEA-Japan U.S. Friendship Commission Fellow added to her professional sensibilities.

When Andrea and Jane Weinzapfel met as interns, they discovered shared values and established a firm to create a bold and refined architecture for the public realm. In 2007, Leers Weinzapfel Associates became the first woman-owned firm in America to receive the prestigious AIA Firm Award, and it has been included on ARCHITECT magazine’s “Top 50” US firms roster since 2015.

Parallel with her practice, Andrea has a continuous commitment to education. She is a former director of the Master in Urban Design Program at the Harvard Graduate School of Design, where she was adjunct professor in Architecture and Urban Design, and she now serves on the university’s Design Advisory Pool. Her previous appointments include Yale University, the University of Pennsylvania, and the University of Virginia. Internationally, she has taught at Tokyo Institute of Technology, National Chiao Tung University in Taiwan, and the University of Paris, Sorbonne. She was a Visiting Artist at the American Academy in Rome and lectures and participates in symposia and design juries throughout the United States, Europe, and Asia.

Andrea’s work earned her the Boston Society of Architects Award of Honor, and was Commissioner for the Mayor’s Boston Civic Design Commission.

Josh Liebla

I never fail to be amazed by our ability as designers to analyze a given problem and nurture our conceptual thoughts into physical solutions. It is for this reason that I welcome both the responsibility and opportunity of shaping our built environment for the better.

Eric Shichen Li

As architects, we do not create. As optimists and idealists, we discover, collect, and appreciate the extraordinary in daily life, distilling these shining moments into choreography using bricks, concrete, and steel.

Katia Lucic, AIA, LEED AP
Associate Principal

Nathan Madidisi
Graphic Designer

Design to me is a form of expression that can be interpreted and used in many different platforms. As a graphic designer I strive to apply design in many different ways to create strong and ever changing work.

Vy Mai, AIA, LEED Green Associate

The process of architecture is an act of optimism towards a world we want to live in. The negotiation of history, site, program and construction into a single vision is fulfilling work. I hope to be a part of creating spaces that inspire communities working towards their own visions of the future!

Layla Ni

Architecture interweaves spatial, temporal, and human dimensions, which choreographs experiences through design sensibility and accommodates needs through creative and sustainable thinking.

Laura Patrick

As an interior designer, I look to environmental psychology to inform design decisions, and believe it plays an integral role in providing a sense-of-place for the end-user within the built environment.

Su Poon, AIA, LEED Green Associate

Design is an optimistic attempt to realize our shared human aspirations while staying humble and rooted to where we came from -the environment, history and culture. And to have fun!

Ashley Rao, AIA, LEED AP Phius CPHC

Ashley joined us in 2016 and quickly became a passionate and articulate firm leader.  She brings a holistic interest in place and people to bear on her work, reflecting her background in both Architecture (Yale University) and History & Literature (Harvard University).

Caitlin Swaim

Design strengthens access. Attention throughout the design process to the forms of access particular to each project – whether equitable, ecological, or playful – allows buildings to establish committed opportunity for both individual and collective experience.


Siqi Tang

Design offers a unique perspective of the world. I enjoy seeing the world through the lens of design, as well as creating societal impact with diverse design strategies.

Kira Tyler, Assoc. AIA, NOMA

Architecture provides us with the ability to reflect on past and present iterations of the built environment, while remaining to exist as a catalyst, encouraging the societies we hope to mold for the future.

Collin Vermilyea

Design is an opportunity to invest in the future equity, vibrancy, and health of the public. As designers of built space and experience, we have the responsibility and honor of this mission.

Matt Vocatura, AIA, CPHC, LEED Green Associate

I strive for a balance between the abstract and technical in all that I make, never forgetting that our hands can be our most powerful tools. From the kitchen to the studio I’ve learned the value of iteration, and that like many things, architecture is both process and product.

Chiajung Andy Wen, Assoc. AIA

Architecture has the ability to direct our consciousness back to the world and towards our own sense of self and being.

Benjamin Wilcox, AIA

“A building’s concept is brought into reality through the details.”

Courtney Wilson
Marketing Manager

I am drawn to ways art and design can play a role in experience through visual story-telling.

Cole Wyatt
In forming meaningful connections with your environment, community, or individual, architecture acts as the framework, which is informed through poetics and individual fervor. Architecture deserves to be felt, and the understanding of its synthesis can make it human.
Reuben Zeiset

Architecture creates and orders the spaces in which we live, work, and play, and good architecture does so beautifully. As a designer, it is a privilege to help shape the world we inhabit and create spaces that enhance our environment.
