Just a few words from our customers

My husband and I were thrilled with the interior design work that Tamsin Mascetti and her team did for us. Tamsin has been the creative leader of three projects for us at two different houses, including two kitchens, a family room, a living room, a dining room, a foyer, and interior paint and hardwood floor selection throughout our house.

Tamsin sets herself apart as an interior designer in three essential ways. First, she has a terrific personality and is just a joy to interact with, even on a stressful project. I never feel like she is talking down to me or bullying me into a design choice that isn’t right for me or my budget. Rather, I feel like she does an excellent job of learning who her clients are and what their tastes are, and encouraging them to enjoy the design process with her easy going personality and positive outlook. Second, she is consistently reliable when she estimates both projected cost and timing for a project. Tamsin takes the guesswork out of a project – she does not over promise, rather, she gives helpful, candid and reliable advice that make budgeting and planning so much easier for a project. Third, she understands the realities of working on a budget and constantly blows us away with her ability to narrow in on the design elements that will make a significant impact and thus deserve a larger share of the budget, and areas where costs can easily be saved. There is not a doubt in my mind that she has not only saved us thousands of dollars, even taking into account her fee, but she has guided us to a design result that we never would have come close to realizing without her help.

I cannot recommend her highly enough. It is a joy to me to walk in my house and see the difference Tamsin and her colleagues have made. I wish I had given up on the notion that I needed to figure out interior design all by myself much sooner and enlisted her help sooner, so I could have enjoyed her work years ago!


I hired Tamsin Design Group on the recommendation of my realtor. We had just purchased a big, old house and a lot of my décor from my previous home just wouldn’t be a good fit. I loved Tamsin and Jackie immediately, which was a good sign, and the whole process was wonderful. They were able to work with some pieces that I had and knew I wanted to keep, were able to design around a budget that was limited, and were able to tap into what we liked and find a style that fit the needs of our family perfectly. There were involved in every step of the process- from choosing window coverings to heading into the field to help choose carpet for stair runners, from going shopping with me to accessorize the rooms once the furniture was in, from answering a million emails and texts asking for an opinion of some treasure (or non-treasure!) that I found and wanted their opinions on. I can’t wait until I am able to call Tamsin and say, “Let’s do the whole upstairs!”. Until then I am just grateful for their help in creating a home that we absolutely love.

I have used Tamsin for several projects at my house and I think that she is fantastic. She has a modern sensibility (unlike my prior designer who was stuck in the Waverly era) and balances esthetic with functionality. She is flexible too – she will design an entire room and go shopping with you to pick things out or will even just hang pictures (in a cool grouping) or shelves on the wall if that is what you need. She has done amazing work for some friends as well. She is very easy to work with – she gets a sense of what you want, gives you a design, and then helps you through the process – letting you make the ultimate decisions but helping to guide you with thoughtful advice. She also do a great idea of blending the male and female feel/desires for a space.


Simply put, PERFECT. I met Tamsin and her associate for the first time and in less then a 20 – 30 min. meeting the project was set. The expectations were high especially from my two teens, but as a single father, the key word was budget. Tamsin Design group delivered beyond all of our expectations, transformed some of our space beyond what we thought it could be. I would recommend TDG to anyone for any project.

I had the pleasure of working with Tamsin on a few design projects for my home. She was amazing, very helpful, responsive, and did an overall great job. I plan to use Tamsin Design Group for my future design projects.

As a custom home builder, one of, if not the most important elements to the construction puzzle is the homeowner’s designer. Tamsin and her team at Tamsin Design Group, absolutely knocked the ball out of the park on our project, not only for us as the builder, but also for the homeowner.

One of Tamsin’s real strengths is her knowledge of the residential construction process. This is something that is rare among many designers but is so critical to a projects success.

Additionally, any home builder will tell you that three of the most important traits among a designer are that they are:
1) Responsive
2) Make themselves available for last minute meetings
3) Has the ability to communicate clearly with her clients so that decisions can be made quickly
Tamsin and her group excel at all three of these.

Finally, no designer can be successful without having good taste (duh!). Well, Tamsin has an impeccable design eye and a style that translates to anyone’s design preferences.

The Tamsin Design group was hired to complete our kitchen remodel in our Victorian home, built in 1877. Tamsin was incredibly easy to work with; always professional and always listening. She worked within our budget while putting out needs and desires first. She listened to every idea we had and made them reality. More importantly, she found the compromises we couldn’t find and made us both happy. I highly recommend Tamsin and continue to use her services to this day!


Seeking a designer for our new bar location I knew would be a challenge under our current circumstances. We had met with so many designers in our area but found disappointment when it came to their definition of elegance , warmth, and a romantic environment. Then I had an opportunity to meet the people at Tamsin Design Group. WOW! What a difference immediately. They verbally understand my vision as if I was not the only one. Took it and showed me samples and product to fit my every desire.

WOW again! Their knowledge in the industry and actually being trained and educated in design was a huge sale for me. On top of the fact that the renderings and design plans came back “spot on”. Most people “rant and rave” about whats not right with a situation. I promise I will “rant & rave” with what is right about this situation! Tamsin Design’s Groups professionalism, working with my staff and the positive comments I have heard from them are outstanding! I recommend this agency no matter where in the world your located! They are great!


I have my own business sewing custom window treatments, valances, pillows, etc. It has been a privilege to work with Tamsin for the past seven years. Her talent for design and her style make my job enjoyable. No two jobs are ever alike. She listens to the clients needs and executes a plan that reflects the clients personal taste and preference….and every job has the same end result. Beautiful!

Tamsin is a joy to work with personally and professionally. I happily refer Tamsin to clients and friends who are in need of design help.

We are about to start on our fourth project with Tamsin and are thrilled with the way everything else has turned out! Our first project was a family room make over then we did a complete 1400 square foot lower level with stacked stone fireplace, bar and wine closet. Our third project was adding lots of lighting (can lights, chandeliers and fixtures) to our main level. Can’t wait to start on the next one which is a redo of a place at the lake.

Tamsin has a terrific eye and quickly learned how to incorporate our tastes with a great design style. There have been many times when she has brought samples for me to review and pick for a project and everyone one of them was perfect and I had a hard time choosing. She respects our budget and always had a variety of ideas and suggestions based on how much we have to spend on each area.

I had not done much with a designer before. Because doing renovations and buying furniture involves some expenses, I was so happy to have found Tamsin. I know each project will turn out looking better than I had imagined and it always reflects our style (while staying true to our budget). She works efficiently and is conscious of deadlines. She is very easy to work and is a great project partner!! Can’t wait to see what she has in store for our place at the lake… I know it will be stunning!!
