    Wouldn't consider hiring anyone else. Dennis has it ALL - professional and incredibly talented. Kind and fun to work with but, never misses even the most minute detail. Some projects can feel overwhelming but with Dennis, you know immediately you're in the most capable hands. The results of this project far exceeded my expectations and my expectations were HIGH. Pure talent - if you can get him, HIRE HIM!

    We have had the pleasure of working with Mr. Dennis Duffy for over thirty years. These projected have included major residential renovations in nyc and San Juan, Puerto Rico along with some commercial sectors. In all of these, he has exhibited a keen eye for design, space, form, and function in very different settings along with the ability to work with different personalities balancing their goals and expectations.

    We have found him to be detail oriented and also flexible in both design approach and budget. He has a strong ability to blend existing furnishings and artwork with the architectural setting, layering pieces that he designs specifically for the project, when appropriate. He has always paid attention to our unique interests and needs and made sure they were satisfied. He is able to work well with other team members, architects, builders, tradesmen or condo boards, and coop boards in New York City and San Juan.

    In short, Dennis is one interior designer, friend, and great human being!

    Dennis is amazing.

    We are home builders and we have worked with many firms. Dennis is not only an exceptional design talent but he brings a solution-based approach to his creativity -something that is a rare combination of talents in his field.

    One example is he staged a house for us and it sold within days at the highest price ever in that market ( 1.4M)

    We recommend him to all of our clients without hesitation.

    Love him! Dennis is the best interior designer there is! We chose him after a long review of other professional interior designers and have never regretted it. His designs are thoughtful and interactive. His taste is of the highest caliber, but he always offers several options and starts over again if the owners’ concept or the facts on the ground require it. Most importantly, he is always available. He designed us safely and happily through 2,400 square feet that had not been touched since sometime before 1996. We had every conceivable problem a condominium Board of Trustees could throw at you, but he was diplomatic and confidence-inspiring throughout. We commend him to anyone looking for an interior designer and do so with the strongest possible enthusiasm. See the results here at https://www.nehomemag.com/a-renovated-condo-in-charlestown/

    My project consisted of a total renovation of my kitchen and two half bathrooms, painting, staining, wallcovering, hardwood floor refinishing, new lighting fixtures, and window treatments for the entire first level of my home. Also,my staircase was updated with new contemporary balusters. I was extremely satisfied with the professionalism of the firm and the attention given to every detail. I was amazed by the total transformation of my home and how the whole project came together. My designers ability to combine the contemporary look that I wanted while keeping the original character of my Tudor home was not easy. I had complete confidence in all the decisions I had to make due his incredible taste and knowledge. I would not hesitate to recommend Duffy Design Group and look forward in working with Dennis on future projects.

    We've worked with Dennis on multiple projects - a Back Bay condo, a home in Newton, and a second home in Nantucket - over a span of 15 years. He is a tremendously gifted designer with a wonderful eye and an ability to listen carefully and develop ideas that reflect your tastes and are appropriate to the context (e.g. newlywed condo in the city vs. a home for a young family). He has his fingers on the pulse of what's available from leading vendors but is also quite talented at developing original designs; our bedroom furniture, two couches, several rugs, and a kids table with Warhol-inspired painted flowers are all among our collection of original, custom Dennis Duffy creations. Dennis doesn't constrain his initial ideation process with what things cost - and we have some very expensive bar stools that we fell in love with to prove it - but he will also work toward a budget if asked. We gave him a fixed budget for a new 6k foot home on Nantucket - comprised of hundreds of items - Dennis managed a detailed spreadsheet in designing the entire space and was the only partner we worked with in the process who actually hit their budget.

    Dennis is a truly gifted designer and a great guy and we highly recommend him!

    Eight years ago we hired Dennis Duffy of Duffy Design Group for a re-do of our uniquely shaped family room. When he said we could feature our beloved Beatles pictures above a sofa, we knew we had found the right guy! We just completed an update of that room with him. The original project involved custom made L shaped sofa, end tables, coffee table, wall shelves, media unit, accessories. The room has 10 foot ceilings and they are even higher near the window.

    In a problem corner behind the sofa he installed a wall mounted lamp over a table. It was a very contemporary look and a design element that just makes the room seem bigger. The recent room update changed the accent color from red to blue and featured a new rug (the original rug was 12 years old), and toss pillows.

    This was the first of many projects we have done with Dennis Duffy. Dennis does a great job. We highly recommend him

    We worked with Dennis and Duffy Design group twice, when we first moved to the Back Bay and ten years later when we wanted to renovate the house we have been living in. We will work with Dennis again and again and we would highly recommend DDG to all of our friends. Dennis always treated us with utmost respect. He was able on both occasions to listen, understand our vision and transform our house into a practical and beautiful haven. He respected our budget and he helped us on many occasions to deal with difficult situations with our subcontractors. His team is The A team, courteous, reliable, professional and always answered our questions in a timely fashion; all combined with an exquisite taste and a true love of design....
