Meet the founder

holly gallagher

Holly received a certification and education in space planning, color theory, period furnishings, custom window treatments, and furniture construction as the In-Home Designer at Calico Home Southlake before establishing Gallagher Interiors in 2006. 

Many of her clients made the transition with her, and her business had been powered by the referrals of happy clients ever since.

Holly’s easy communication style enables her to quickly tune in to her client’s design desires and create the ideal home for them. Her experience and expertise, along with her warm  personality make her clients feel comfortable and confident throughout the process. Holly enjoys long-term relationships with many of her clients, and has helped several of them build and furnish multiple homes. Some of her favorite projects are lakefront homes and the wine and whiskey rooms she has created for her clients who love to entertain, relax, and unwind in their homes.

Holly continually expands her knowledge by regularly attending industry market events, vendor presentations and ongoing education classes. This enables her to expertly guide her clients, taking out the guesswork, saving them time and money, alleviating stress, and empowering them to make the best decisions for their homes.

what people are saying

Holly was recommended to us by a friend and she quickly established a rapport that gave us confidence that she would be able to transfer our desires into a cohesive plan to meet both our goals of updating and brightening our spaces, but linked to our existing taste and other areas of our home. After reviewing the plan, she took us to several providers to ensure we were in agreement with the overall approach. Her professional network enabled access to items we would not otherwise have seen and ensured we had an outcome that was tailored to our vision. Holly kept us apprised of work in progress and exceeded our expectations. We love our "new" home and the professional but livable approach that we now enjoy. Holly was a pleasure to work with, was responsive and finished on schedule and within budget!

Holly came to our home & spent time getting to know us before starting our reno. She listened to our ideas and went from there....We loved everything she picked out. She has an amazing eye for color!!!!! She came highly recommended by a close friend...Now our friends are using her again. We will be calling on Holly again in the near future for a master bedroom & bathroom remodel.

Rick & Lynette L.

Holly is amazing! Our project is a complete home interior furnishing with some small construction upgrades as well. Holly has designed the home from top to bottom with impeccable taste and creativity. Our home is truly unique to us with one-of-a-kind pieces and custom decor. Every room design flows effortlessly into the next. The quality of furniture and decor selections is excellent and always within our budget. Holly listens intently and is always concerned that her choices are exactly what the client is imagining. She is comfortable with design changes and is timely in finding alternatives and solutions. She always follows through with pending orders and maintains an open line of communication with her clients. We are thrilled with our home design and blessed to know Holly!

Holly helped us completely redesign our living space in a home we purchased last year. After carefully listening to our concerns, Holly helped us set a reasonable budget that would deliver the outcome we hoped for. It was a gorgeous design that has been very well received by all who have seen it. Holly is a joy to work with. She is extremely creative, very talented and she has become our "go to" designer. We look forward to working with Holly on our next project.

Colleen A.

We thoroughly enjoyed working with Holly at Gallagher Interiors. From the start she was able to see my vision for a master bathroom remodel but then took my vision and made it so much better!! Holly is extremely professional in her work and very knowledgeable about design and trends. She is a great communicator and responded within the day to answer questions or help with concerns. This was our first time working with an interior designer and it has been the best experience. I'm looking forward to more projects in the future!

Brittney B.

Holly transformed an unused formal living room into a functional space we adore! She helped us pull a bit of our Old Ky Home into a bourbon lounge and library. Holly has great taste and helped us create a room that we have used so much over the holidays for entertaining. We have received lots of compliments from friends and family on Holly’s design. We highly recommend Holly and love our little piece of Kentucky in our Texas home!

Renee M.

Holly with Gallagher Interiors created a beautiful home for us. We moved into a new house. We had some things that were important to us and wanted an updated look. Holly did a fabulous job of incorporating our existing pieces to the plan she created for our new home. It looks fabulous and still has our family traditions in place. Holly did everything from window treatments, to furniture, to artwork and all the finishing touches. I felt that she captured my heart and soul in her design for our home. She communicated updates and deliveries on a constant basis and stayed within the budget we established.

Jackie S.

Holly Gallagher is fabulous! She used her talent and experience to redesign our living room to a beautiful and personalized style that we absolutely love.

Jan S.

Holly was wonderful! I asked her to make our home pretty - and she did! Her suggestions - furniture, artwork, granite and ways to improve our home - were right on! She treated our project as though it was her own home being worked on. She was very budget conscious and represented our desires throughout the process with the various subcontractors who worked with us. Thanks Holly for a great experience and making us love our home once again!

Jackie L.

Working with Holly is so fun and easy!! She quickly figured out our style and combined the most beautiful patterns, colors and textures to create an elegant yet comfortable home for our family's wishes and needs all while staying within budget!! I absolutely love it!! I’m looking forward to our next project with Holly!

Lauren P.

I can't say enough about the value of all the suggestions and decisions Holly made to help us with our project!! We couldn't have done it without her! She is the BEST and so knowledgeable!! Her expertise is very diverse, and we are truly thankful for all she did to help us transform the look of our home!!
