“The preschool staff and I love our new classrooms and facility. Our classrooms are even brighter and more beautiful than ever and our students are as engaged as ever! M+dN did a truly outstanding job from start to finish and exceeded our expectations in every way imaginable.”
Jasmine Milone, Washington Street United Methodist Church Preschool

“Our experience with Maginniss + del Ninno Architects during the construction phase was excellent. M+dN showed extensive knowledge of not just what they had designed but also design and construction standards when confronted with unforeseen conditions.”
Steve Nicholson, Office of Design and Construction, Fairfax County Public Schools

“This successful experience has confirmed that ACPS would like to continue with this type of construction as it proved effective in saving time in addressing the ever growing ACPS student population and was less disruptive to school operations and school sites.”
Alexandria City Public Schools FY 2013 Proposed Capital Improvement Program (CIP) Budget.

“In a nutshell, they are a truly client centered architectural firm. Other firms may claim that they are, but BMK (Maginniss + Del Ninno) really ‘walks the walk’.”
Chuck Petrick, Supervisor of Construction, Caroline County Public Schools

“…It has been a pleasure to work with BMK (Maginniss + Del Ninno). Going through a major renovation while students are attending school is very difficult. Because of their support, the process was made much easier for everyone. They were always available when I had a question or concern… I would highly recommend them…”
Donald E. Thurston, Principal, Robert E. Lee High School

“…With an eye for attractive design and an ear for budgetary restraints, BMK (Maginniss + Del Ninno) often incorporated both my suggestions and those of other field personnel into their solutions and directives. This was truly a team effort and one which I am very proud to have been a part of…”
Michael S. Long, Site Supervisor, Fairfax County Public Schools

“Throughout the entire design development and construction process, we were continually amazed at your firm’s ability to face difficult challenges and to prescribe sensible solutions to complex problems. One particular case in point was the fact that we soon discovered early in the project that the majority of the original structure was constructed without footings… We want you to know that the entire community is delighted with the final outcome of the project and to date we have received innumerable compliments regarding the newly completed Community Center.”
William T. Clark, Construction Manager, Office of Capital Construction, Loudoun County
