She helped me select paint colors for both the exterior and interior of my home, and her expertise made what can be an overwhelming process feel easy and enjoyable. She has a great eye for color and really took the time to understand my style, the character of my home, and how the different spaces needed to work together. I’m so pleased with the final selections and would highly recommend Mary to anyone looking for thoughtful, knowledgeable guidance with color. **★★★★★ — Joey Young, Aug. 2026** > Mary Fidler of Design Intervention was amazing to work with! She helped me select paint colors for my living room, entryway, dining room, and kitchen, while also coordinating everything with my flooring, hardware, window treatment, carpeting, and light fixtures. Mary is incredibly knowledgeable, thorough, and has a great eye for design. She took the time to listen to my needs and made the entire process easy and enjoyable. I felt confident in every decision because of her expertise. I highly recommend Mary to anyone looking for professional color and design guidance. **★★★★★ — Jodi Westerham, June 2026** > Mary did an absolute exceptional job helping us choose a new exterior paint color for our home! Picking paint colors can be such an overwhelming process, but she completely took the stress out of it. > > She was incredibly thorough, making sure to take our existing brick, the roof tone, and the color of our doors into consideration so everything would blend perfectly. We are absolutely thrilled with the results and our home looks beautiful. > > If you are struggling to find the right shades, I highly recommend Mary—she made a daunting decision so much easier, and I will definitely use her services again in the future! **★★★★★ — HU-317303761, June 2026** > Working with Mary was such a fun experience! Not only did she help me make confident decisions about colors and design for my home, but she also taught me so much throughout the process. I learned how color works in different spaces, how lighting affects paint choices, and how to select colors that complement one another and the room's overall feel. > > Mary listened carefully to my ideas, helped me refine my vision, and gave me confidence in the choices we made. What I appreciated most was that I didn't just walk away with great color selections, I walked away with a much better understanding of design and color in general. > > I highly recommend Mary to anyone looking for expert guidance, a collaborative experience, and someone who truly enjoys helping clients create spaces they love. **★★★★★ — Anne Nelson, June 2026** > Working with Mary at Design Intervention was a relaxing, interactive, educational experience and I HIGHLY recommend her. She was prompt, thorough, had great timing in terms of feedback and questioning.... She is clearly a gifted designer but also pays attention to structure, followup and processes. She is friendly, professional, prepared and intuitive. I would hire her again in a heartbeat! **★★★★★ — HU-401509111, May 2026** > I had such a great experience with Mary and am so grateful to have leaned on her knowledge and expertise. I truly felt heard and that Mary understood my vision for what I was hoping to accomplish and helped bring that to life. **★★★★★ — HU-143050787, May 2026** > We recently picked colors and discussed options for main house color and trim with Mary. She was helpful and has good insight on how to evaluate a color, by looking at it in different light, and using larger swatches. We took her advice and painted our own samples and found a color we love. We are very happy with the completed project and are thankful for Mary’s expertise and advice. **★★★★★ — Laura Dolan, April 2026** > Painting the exterior of a house is a big investment and I want to be absolutely sure we choose the best colors for our home. Mary's color consulting service gave me total confidence in our selections and peace of mind that we will love the colors we chose. Mary had me fill out a questionnaire about our project and send any inspiration photos I liked before we met. This ensured that our time together was productive and efficient. She had many large samples that we could look at to make our decisions. I am so happy with the color palette we chose. Mary is detail-oriented, which I really appreciate, she arrived on time and is very thorough. She ensured that I thought about every exterior surface and what to paint which color. I am so excited for our project to be complete and I think Mary's fee is well worth it. I highly recommend her services. **★★★★★ — Megan Relson, April 2026** > Mary was a god send with our resale project on our beloved first home. She helped make what could normally be a stressful project making our home refresh look cohesive and palatable to us as well as future buyers, effortless and fun. We highly recommend Mary and look forward to using her services on our new home! **★★★★★ — mlbezak, Feb. 2026** > Mary was amazing to work with! She helped us feel confident and respected in choosing interior paint colors that feel cohesive with the existing finishes and constraints. She came highly recommended to us and I can see why - wish I had contacted her even sooner! Her services are worth every penny because of her methodology, talent, and passion. I can’t wait to get started on our painting projects. **★★★★★ — Callie Myers, Jan. 2026** > Mary knocked it out of the park helping me select colors for my entire home. She listened well to my thoughts and concerns, gave me options where I needed them, and also pulled out some surprise recommendation that worked wonderfully! Her involvement helped me avoid so much stress, and helped make my project a success. I love all the new colors she helped me select. Thanks, Mary! **★★★★★ — HU-292857173, Jan. 2026** > I have worked with Mary on projects in two homes. Both times I came away in awe of her expertise in color! She is simply amazing. Mary takes into consideration the homeowner's preference of course, but also lighting, the stone, tile, flooring and other fixed features that must be worked with. Her ability to see the subtle differences in colors is what makes the final product from working with her "outstanding" rather than just "nice". I highly recommend Mary and know that if I have another project she is the only designer I would consider working with. ## Selected projects - [North Oaks Interior](https://www.houzz.com/hznb/projects/north-oaks-interior-pj-vj~6382580) - Location: North Oaks, MN - Photos: 6 - Description: Beautiful whole-home renovation with new paint throughout!
