I had several shade design companies But none of the fabrics were the color I needed. Then I ordered the fabric myself and couldn’t get a Shade designer company to make the shades without purchasing thru them. Dian did a beautiful job. Professional and friendly demeanor. I highly recommend Dian. **Comment from Designs by Dian Window Treatments:** > Thank you, Denise! What a pleasure to work with you and your Mom. **★★★★★ — Holly Ackman, Nov. 2018** > Dian! Your service excellence has delighted me not once, but three times! You are the consummate professional. Your work is impeccable, and your responsiveness to service requests sets you apart from the normal contractors. When I needed a "tune up" to one of your installations, you showed up as quickly as you did for the original installation. I rate you a "10" and recommend that anyone who wants a true professional to hire Designs By Dian! **Comment from Designs by Dian Window Treatments:** > Thank you for your glowing review, Holly! I look forward to helping you with your future projects. Dian :-) **★★★★★ — ebh98yl, Dec. 2015** > "Dear Dian, > > It is with heartfelt and most sincere “thanks” that we write to let you know how very much we love, appreciate and enjoy all that you have done for us all these many years. > > Everything has turned out beautiful “thanks” to your amazing, creative and artistic talent.

We are thankful not only in being one of your many clients today—we are blessed because we also think of you as a good friend—one of life’s blessings we will always be thankful for. > > Dian, we especially want to thank you for the kindness and caring way you helped and guided us through a very difficult time this year when our home was so badly damaged by all the water after it flooded. > > We are very happy and pleased with all our draperies, the bedspread and bed ruffle, sheers and pillows that you created and made for us. As well as many other decorating and remodeling needs. > > Everything has turned out beautiful—it all flows together so nicely. Gee, it’s almost like having a new home.

Now we can relax and enjoy our home. > > We wish you many more years of continued great success and blessings of happiness. > > Thank you again, Dian > > God Be With You! > > Love, > Barbra and Earl Horstman > December 2010" > > PS: Here we are, December 2015, and in thinking back about all the projects that Dian has helped us with -- we are still very happy with everything. We trust her and we are grateful for her decorating talent and expertise. She can do anything or knows how to get it done. Whatever Dian does for her clients is done with their likes and thoughts foremost in mind -- that is why we are so pleased and happy with all she has done for us. **Comment from Designs by Dian Window Treatments:** > Barbra and Earl, I have loved working with you over the years. Our visits are always special and I look forward to your next project! **★★★★★ — Karen, Oct. 2015** > This is the second project Designs by Dian has completed for me. The most recent project was challenging because of the size of the glass sliding door and the desire to have sheers as well as a contemporary curtain. Dian started with excellent consulting services recommending fabrics and hardware and within days provided samples for me to consider and test during different times of the day. Her team's finished project is exceptional. Each aspect was perfectly executed and extremely polished. I love my bedroom now! I'd highly recommend Designs by Dian to any of my friends and family without hesitation. **Comment from Designs by Dian Window Treatments:** > Thank you, Karen! You are a joy to work with and I'm always here to help you with any future projects. **★★★★★ — feiners01, Sept. 2013** > I have always shied away from window coverings because I felt they would make a room feel closed in but I contacted Dian to see if she had any ideas. She spent hours with me, sketching out possible ways to frame my windows. She did three rooms and an entryway - all different designs. I felt she really took the time to understand my preferences and was so helpful. The final product is perfect and I was impressed by the quality of everything - this is not "off the shelves" kind of products - totally customized and I am thrilled with the results. She also helped me select chairs (again, spending hours with me) and then I ordered pillows from her for them. They are beautiful as well. I highly recommend Dian! **Comment from Designs by Dian Window Treatments:** > Jackie, your project was lots of fun, and I enjoyed working with you. ## Selected projects - [Lake Mission Viejo Retractable Solar Shading](https://www.houzz.com/hznb/projects/lake-mission-viejo-retractable-solar-shading-pj-vj~5576707) - Location: Not specified - Photos: 2 - Description: Custom Sunbrella Retracting Sun Shades.
