The History of Tandem

With 2019 bringing exciting changes for Tandem. We wanted to take a look back at how we got here. From 2004 and beyond, read below for a bit of background on the history of Tandem.


Tandem was started when Tony Andrews, Sean Staunton, Chris Walsh, and Dimitri Nassis joined together with the vision of building new single-family homes on the north side of Chicago, IL. The entire team was looking for career changes and to scratch a collective entrepreneurial itch. It all came together at their first office located in Roscoe Village at 1720 W School Street. The vision only grew from there and they quickly took on and sold their first new home project by October 2005.


Since then, the scale of their projects has changed rapidly. This was kick-started by a large scale six-unit condo building completed in January 2008. Internally they also pushed to grow and change processes that have resulted in projects ranging from a meat packing facility, to a low rise apartment building and now a high rise apartment building at 730 North Milwaukee.


These changes in project size have also merited a growth in staff. What started as a group of four is now 25 and counting thanks to project expansions. Thanks to the efforts of the team, a bright future is certainly in store. Most recently, the team has taken on 730 North Milwaukee with the grace of a well-established builder. This high rise apartment building with both residential and commercial space is nearing top-off come the end of February 2019. Taking on a project of this size has only inspired Tandem to continue challenging themselves.

And Beyond

After the completion of 730 in January of 2020, they will begin two projects in the West Loop. Both are 200 unit buildings who’s completions are anticipated to be mid-2021 and 2023 respectively. After the addition of these buildings, Tandem will be managing about 700 units including their prior properties. Looking even further in the company’s future, they’ve explored a number of ideas including development opportunities in other cities. With a growing portfolio of diverse projects, a hard-working team that is always ready to solve challenges, and leadership committed to using cutting edge processes, Tandem is sure to leave an impressive legacy in the years to come.”
