About Us

DoodyCalls® of Denver

Craig and Jo Ann Hammer opened DoodyCalls of Denver in 2011 after careers in purchasing and transportation. Servicing Thornton, Arvada, Littleton, Lakewood, and the Greater Denver area, we are passionate about helping to keep our community clean, safe, and pet waste free.

We were drawn to the DoodyCalls business model for several reasons. DoodyCalls allows us to make a positive impact in the community by providing a necessary service. As Colorado natives with strong ties to the local area, we feel strongly about supporting both residents and communities within Greater Denver, Lakewood, Thornton, Arvada, and the surrounding areas. Jo Ann is also involved in Denver’s local chapter of Impact100, a collective giving organization that empowers women. As pet waste is classified as a non-point source pollutant by the EPA, we were also drawn to the fact that DoodyCalls benefits not only the residents of our community, but also the environment in which they live.

We also have two dogs of our own: a ten-year-old yellow lab, Zoey, and a four-days-a-year “hunting dog” that can be found sleeping on their bed any of the other 361 days. As dog lovers, we enjoyed the idea of opening DoodyCalls as a fun family business. Since 2011, we have proudly provided high-quality pet waste removal services to thousands of residential and commercial customers in the Denver area.

By using servant leadership, they hope to build a great, passionate company that develops great people and provides communities with cleaner, safer areas for their families.
