The Founder

Madeline’s Meticulous began with Madeline Costanzo, whose passion for cleanliness and dedication to exceptional service laid the foundation for our company.

After budget cuts led to the elimination of her dream job at The American Red Cross, Madeline channeled her zest for life and people into starting her own cleaning business in Salt Lake City in 1992. Her commitment to meticulous cleaning and customer satisfaction quickly earned her a loyal clientele.

In 2000, Madeline relocated to Scottsdale, Arizona, where she expanded into the multifamily housing market, new construction, and condo conversions. Her sudden passing in January 2007 was a profound loss, but her legacy lives on through her children, who continue to uphold the high standards she set.

The Legacy

We lost Kelli Terwilliger in 2021, but her dedication, leadership, and expertise remain an integral part of Madeline’s Meticulous. Her impact on our team and clients continues to inspire our work every day.

Her presence is deeply missed, yet both she and her mother, Madeline, live on in spirit, serving as the driving force behind our commitment and dedication to the family name and business. Their passion, values, and work ethic continue to shape everything we do, ensuring that Madeline’s Meticulous upholds the high standards they set.
