         After graduating in 1970 with an associate’s degree in Architectural Engineering Technology from
Wentworth Institute of Technology in Boston, Massachusetts, John F. Sullivan, Jr. worked for William J. Gavin
Associates in Lowell, Massachusetts. There he was a field supervisor for residential and commercial projects, an
architectural draftsman, and a schedules coordinator, as well as being named Treasurer in 1986. In 1980 he
attended Boston Architectural Center in Boston, Massachusetts gaining valuable knowledge of architecture. In
1982 he founded New England Design Build, Inc., which entailed residential and light commercial construction.
He still owns NEDB but now restricts much of the work to major projects such as financial institutions and
subdivisions. In 1986 he became President of William J. Gavin Associates, changed the name in 1997 to Gavin
& Sullivan Architects, Inc. and focuses on residential, commercial, and historical architecture.
       His extensive experience in the field of architecture and construction has facilitated him to be successful
today. The knowledge he has gained through his education and his vast experience has allowed him to work on
an array of projects from simple additions to complex commercial buildings.

Joined Gavin and Sullivan Architects in 1983 after working for Architects and Associated Designers, Inc. in Boston.

  

       In 1982 Mark D. Wilcox graduated from the New England School of Art and Design in Boston,
Massachusetts for Interior Design. In 1979 he began working for Architects & Associated Designers, Inc. located
in Boston, Massachusetts as an architectural designer and draftsman, as well as a presentation specialist. After
working a few years in Boston, Mark ultimately decided he wanted to work closer to home and in 1983 joined
Gavin & Sullivan Architects, Inc (formerly William J. Gavin Associates). He has worked as an architectural
designer and draftsman and presentation specialist and specifications for nearly twenty years at Gavin &
Sullivan.
       After working for almost twelve years he decided to further his education and completed courses from
The Lowell Institute School @ M.I.T. in 1995 in the discipline of AutoCAD I, II, and III and Computer Literacy.
His knowledge in commercial architecture is extensive and since he has a degree in Interior Design, he
has a knack for design and spatial aspects. He specializes in our larger projects such as commercial properties
and large homes.
