Prior to moving to the Berkshires, Jennifer specialized in corporate interiors, office standards and systems furniture for a large New Jersey architectural firm.  In 1999, with her children in college or embarking on their own career, she decided the moment was right for a change.  Wanting a rural environment in which she could take a walk in the woods or stroll into town for a cup of coffee, she found the perfect spot in Great Barrington.  

A few months after making the move, she found a position at Clark & Green. With her corporate interiors, she made an easy transition to residential interior design. Her sensitivity and skill in selecting colors, fabrics, and fixtures along with her organizational skills have made her an invaluable asset in residential and commercial projects.  Along with filling a critical role in the project design process and implementation, she manages the day to day operations of the office.


Arriving in the early 1970’s, when his car broke down on the Massachusetts Turnpike, Stephan worked as a carpenter for three years in Berkshire County. He gave up his carpentry tools to study architecture at Pratt Institute in Brooklyn. After working in NYC Stephan returned to the Berkshires in 1988 to establish Clark & Green. Initially focusing on residential design, Stephan expanded the office’s work to include a variety of commercial building types. These projects required an broader understanding of design and construction that enhanced his residential design skills. These projects include an award winning transformation of an historic building into the multiplex Beacon Cinema in Pittsfield and the conversion of an athletic field house into the 32,000 square foot multi-use Elayne P. Bernstein Theatre complex in Lenox and the award winning Great Barrington Fire Station.

Stephan is a longstanding member of the West Stockbridge Zoning Board of Appeals, serves as Chairman of the Design Advisory Committee of Great Barrington and is a Board Member of the Berkshire Community Land Trust.


Originally from North Carolina Glenn began his college as an art student before transferring to the School of Architecture at Cooper Union in NYC. During this time he spent a year traveling and working in Europe and the Middle East. This experience intensified his appreciation of the built environment and its impact on the individual human experience and its relationship to history, philosophy, and artistic traditions.

Glenn’s drawings and models have been exhibited and published in books, magazines and periodicals. They include representations of a wide range of projects - private residences, apartment buildings, museums, churches and synagogues, commercial offices, university buildings, schools, city plans, stained glass windows, a mural and an award winning short animated film.

His early professional life was spent in NYC, the world’s greatest laboratory for architecture. Glenn joined Clark + Green in 2000 to be part of its strong commitment to design excellence and its connection to a local community. His role as designer and project manager requires sensitivity to the importance of local history and traditions while celebrating the variety and innovation of individuals and cultural institutions unique to the Berkshires.

He relishes walking to work and to downtown Great Barrington with his wife and two children


Steve McAlister has practiced architecture continually since 1977, in Salt Lake City, New Orleans, Connecticut and Massachusetts. His work in New Orleans included several years with August Perez, which was the New Orleans partner firm of Charles Moore. This diversity of background gave him experience with both large and small projects, as well as with new and existing buildings. Of particular note is his background with historic structures and historic districts, including the French Quarter, the Hartford region, Boston and Cambridge, among others.

He is a strong proponent of the idea that being a generalist is an advantage over narrow specialization in the practice of architecture, leading to the introduction of new ideas into established notions of building type and their design. His body of work is primarily in the commercial, institutional and nonprofit sectors, and his projects involving new and historic buildings have received AIA and other design awards at the city, state and multi-state regional level.

Steve is former chairman of the Planning Board of Tolland, MA and current treasurer of Berkshire South Regional Community Center.


Rebecca has been working in architecture since graduating from Wentworth Institute of Technology with a degree in Architectural Engineering Technology in 2006. Upon graduation, she moved to Providence, RI where she worked at two small firms gaining experience on projects ranging from affordable & high end residential to educational, religious & industrial facilities. Through those projects she carried out all phases of design, documentation and construction administration, working closely with clients, consultants and co-workers. She joined the team at Clark + Green in 2012.

Outside of work, Rebecca has also brought her architectural background in to personal projects as well.  In 2011 they worked together again to design and build a teardrop trailer that they then used to travel across the country before setting back in the Berkshires where they both grew up.  She also is a member of the Egremont Historical Commission and enjoys working on husband’s family dairy farm and with his malting business.

Brian graduated with a Masters of Architecture from Wentworth Institute of Technology in 2009, a member of the first class to receive a Masters degree.  He gained experience in the commercial field while working during college and proceeded to work at a small firm specializing in residential construction following graduation.  Enjoying the dynamics of sharing ideas, asking advice, and client collaboration that comes with the small office environment he happily joined the team at Clark + Green in 2016. 

Brian and his wife Chelsea recently settled in the Berkshires after spending the prior 12 years living in Boston.   They began the new chapter in their lives by designing and helping construct their own home with the help of family and friends.  They look forward to exploring the picturesque towns of the Berkshires, getting to know their new community, and finding great outdoor activities with their dog Bergen.
