**★★★★★ — Kathy Olson, April 2018**

> We hired Katie to help us design a remodel to our existing back yard.  We found Katie to be a great listener and a true professional.  She really understood our vision and suggested creative ideas to help it become a reality.  Katie not only added her own flair, but she worked with us to come up with solutions that far exceeded our expectations.  She met every deadline and her pricing was very fair.  We highly recommend Zinnia Design for your landscape design needs!

**★★★★★ — Ceramic Design, May 2016**

> My experience with Zinnia Design was exceptional. The owner, Katie Seidenwurm, was a pleasure to work with. I had seen her work at a neighbor's house and contacted her. Katie came to my house several times documenting my current landscape and redesigned my wish list to transform my yard. Her finished product contained more that I had expected with colored schematics, blueprints, photos and overlays of the new plans. All the hardscape had accurate dimensions and the landscape was labeled. Her drawings made my contractor's job very easy.

**★★★★★ — Stacy, Nov. 2014**

> We were struggling when trying to decide on what to do with our backyard makeover. Katie took photos of our existing back yard and drew up a design plan which she placed over the photos. This really helped us visualize what our backyard could look like. From helping us decide on our patio cover to helping us choose the right landscape plantings, she was great!  Katie was professional in making and keeping appointments with us and we are very happy with our results.
