What our clients are saying

  • Oh my goodness there is so many amazing things to say about Jill and her services I don’t even know where to begin! From the beginning she was so intentional with meeting us where we were at, helping us ideate on interior design visions, and help us execute with as much guidance as possible. As first time homeowners, my husband and I had never made any mood or vision boards and so we knew we needed professional services. She has helped us design literally half our home and we are so in love! Slowly but surely we are bringing it to life and we will update with photos! If you need help with any interior design projects Jill is your girl!

  • Highly recommend Jill. We just wanted some additional ideas as we did our own research and take our project over the goal line. Jill did exactly that for a fixed fee. We bought the furniture etc. ourselves. Thanks Jill!

  • hired Jill to stage my 1 bedroom apartment for an immediate sale. Jill’s professionalism, courtesy, and proactive communication throughout the process gave me peace of mind, which was important as I was living across the country. Jill has a great eye for detail and was able to find creative workarounds to help bring my apartment to life. The apartment was sold within 10 weeks, nearly half of the 21-30 week timeline that my realtor had given me. I would highly recommend Jill for any staging project.
