Our Story

McGuinness Group was founded in 2009 by Deanne McGuinness. Deanne has over 25 years of experience in the architecture and interior design field and has designed over 6,000,000 square feet of space. Deanne worked as a senior member of staff at Elkus/Manfredi Architects for 11 years before starting McGuinness Group. 


McGuinness Group specializes in corporate office, higher education, multi-family and healthcare interior architecture. We have provided design solutions for a wide variety of businesses around the country. 100% of our business is commercial.




Our mission is to provide fresh, holistic and socially responsible spaces that also respect aggressive budgets and schedules. We are dedicated to sustainable solutions that contribute to a more livable world.

Client Service:  We seek to understand our client’s world and to develop solutions to fulfill their mission. We are dedicated to client’s business goals while providing an exceptional and memorable experience regardless of project size, scope or budget. Listening and collaborating with clients to understand needs and objectives and then coming up with design solutions that are unique and meaningful and hit the bulls-eye of their expectations every time.

Process:  We believe in a strong commitment to the design process. From the initial client meeting through occupancy, we have developed an expertise in programming, space planning and providing solutions. We work with clients to identify goals, schedule requirements and budgeting parameters. Ultimately, we develop a design that is sensitive to the individual considerations of the project and reflects and addresses each client’s mission.

Design:  Well designed spaces address a number of different levels of meaning. Design is a powerful catalyst for transforming business, culture and the ways we live and work today. Design should honor the unique qualities of its purpose and place, and be environmentally responsible. Great design is great fun: fun to create, experience, fun to see the reaction of clients when their projects succeed beyond their wildest dreams.
