Design Group of Philadelphia did a fantastic job designing some very challenging spaces is our 150 year-old home. Erin and Ginger were able to combine our lifestyle and their design talent into the perfect spaces. Erin had an amazing way of challenging us to take a design risk - all of which turned out to be some of our favorite results. We look forward to completing more spaces with Erin and Design Group of Philadelphia.

I had moved into a new home and had furnished it but artwork and accessories were badly needed. I was looking for a designer to pull the decorating of my house together. Erin was perfect. She was expertly able to evaluate my needs. She came up with great artwork and accessory ideas as well as an overall theme that pulled my paint palette and furnishings together. Finally I have that AHHHHH feeling when come home!

From the instant Erin walked in we felt comfortable .She was quick to determine a table and chair selection that entirely meet are needs. With our present furniture and the upholstery on the new chairs, she was quick with matching rugs. I was a little surprised at the cost (all costs were specified up front,once selections made),it was a little higher than expected. However,I will say this,looking at the end result we are very well pleased.Erin, surely knows her job and is to be highly recommended.

I had the pleasure of working with the Design Group of Philadelphia while updating and replacing my furniture and decor in my family room, kitchen, dining room and foyer. Erin and her team made the process easy and enjoyable, from the first meeting to the final delivery. I was not able to give them much insight into what my end visions were, but through their questions they were able to offer design options which were better than I could have ever imagined. They understood my style better than I did. Design Group of Philadelphia also did a great job working within budgets and incorporating new designs around existing furniture. I highly recommend Erin and her team and look forward to having them come back out and work on our next home project.

Erin and her very professional team worked with the people of St. John's to redesign and re-decorate our Fireside Room. This "congregational living room" serves as the setting for a Moms and Babies Group on one end of the life cycle to a Family Visitation Room during funerals on the other and everything in between including youth gatherings, 12-step meetings, classes for adults, committee meetings and a dressing room for brides. Their creativity and careful listening skills (to lots of people) resulted in a absolutely beautiful room. Their patience with an extended decision making process was a true gift. Their implementation of the design was professional. The result was a beautiful, calming and functional space that is well serving our congregation and community. One more thing, they were fun to work with!!!!!!

Erin is amazing. What talented, knowledgeable designer. She followed up with everything and met every deadline. Her ideas were wonderful and exactly what we wanted our Residential and Commercial lobby to look like. It is elegant without being overdone or cold. It is warm and inviting as well as beautiful. Our Board was unanimous in their approval of her final designs on our first vote. Will engage her again on other ongoing projects.

Erin helped design a new and improved kitchen layout for us. Erin was absolutely invaluable for narrowing down choices based on my style. She listened to what I wanted, gave me an honest opinion and in the end, a fabulous kitchen!

Erin is nothing if not versatile. She brings a keen eye, fashion sense and a desire to maximize value in every project she tackles. She has designed everything for me from ground floor retail to high end residential and the compliments continue to roll in even years after her work has been completed. I wouldn't not hesitate to recommend her to anyone for any interior design project.

I had the pleasure of working with Design Group of Philadelphia for a previous employer and recommended Design Group to my current employer. I would highly recommend the Design group to any one seeking an interior designer. They will keep your budget in mind while creating a design specific to your needs. I enjoyed working with Erin and hope to have the opportunity to do so again.

Erin and Erin completely redesigned my home office and master bedroom. And WOW...what an amazing transformation. They did an amazing job on both. Absolutely gorgeous. My office is now functional and super chick and totally "me". People are floored when they come in my house and see my new office. And my bedroom now looks like it's straight out of a fancy schmancy hotel. Soothing colors, gorgeous fabrics, and beautiful furniture. I love everything about both rooms. If I knew how to include photos here I would,because you really need to see the before and afters. I know that Erin has taken a bunch. Ask her to post them or send them to you. You'll be amazed!

Erin with Design Group of Philadelphia did a fantastic job working with me on furnishing our newly finished basement. She really listened to my ideas and was able to come up with a fabulous design plan. The end result is one that is both functional yet sophisticated. It is exactly what my husband and I had in mind. We are so happy with the results that we have hired Erin to help redesign a new kitchen for our home.

Erin, Just a short note to let you know that Ang and I are so looking forward to getting started with our renovation project. We are very happy with your quick response to our request for information and to meet. Our meetings were clear and concise and the results are outstanding! The proposals you prepared for paint, furniture style, fabrics, window treatments and lighting were "spot on" with just a few modifications. And, even within our original budget. Our front and back doors will be installed within the next 3 weeks and we look forward to getting started with the remainder of our project.

We had a very pleasant experience as a client of Erin McConnell of Design Group of Philadelphia. She helped us with design decisions and purchasing furnishings, drapery and art for our family room. She listened to our ideas, then provided several options. The entire process was very professional, timely, and smooth. She helped us to create a fresh, young look for a tired old room. We would definitely recommend her services to anyone.

I was need of a major living room makeover. I knew the style I liked, but had no idea where to find the perfect pieces to bring it all together. Erin had taken the time to figure out my likes (and dislikes) and was able to transform my living room into exactly what I was hoping for! She stayed within my budget and offered opinions on where to splurge and where to cut back. She has an amazing sense of design and was able to take away the stress of "trying to figure out what to do with a room!" I have recently hired Erin to design my new master bathroom and work on my bedroom makeover project. I highly recommend her work!
