About Us

A family-run business rooted in Milwaukee — bringing spotless, dependable portable sanitation to every corner of the metro.

Our Story

What started as a commitment to cleaner facilities grew into the portable sanitation company Milwaukee counts on most.

Pinnacle Porta Potty Rental Milwaukee came to life in 2019, born from David Kowalski's deep roots in Milwaukee's vibrant South Side Polish neighborhood. Having spent years managing event operations at the Summerfest grounds and Henry Maier Festival Park — where hundreds of thousands gather each summer for the city's legendary ethnic celebrations — David witnessed a glaring gap in portable sanitation quality. Finding a provider who delivered on schedule, maintained genuinely fresh units, and respected every client seemed almost impossible. He joined forces with Sarah Chen, who brought over a decade of hospitality operations experience from the Wisconsin Center and Milwaukee's bustling lakefront venues. Their founding principle was refreshingly straightforward: give every rental the same level of attention, whether it's one restroom for a Riverwest neighborhood gathering or an entire fleet for a major Brookfield commercial build. From a modest start with a handful of units, Pinnacle Porta Potty Rental Milwaukee has expanded into a comprehensive operation serving the entire Milwaukee County region — yet the core lessons David absorbed working in his family's longtime South Side business remain unchanged: be punctual, do the job thoroughly, and value every single customer.

We exist to provide top-tier portable sanitation that addresses the diverse demands of Milwaukee and its neighboring communities, all while giving back to the areas where we operate. Whether it's tradespeople shaping the next wave of development in Walker's Point or families marking special occasions in their Wauwatosa yards, every individual who steps into one of our units deserves a clean, comfortable, and dignified experience. Pinnacle Porta Potty Rental Milwaukee is dedicated to responsible environmental practices, meticulous operational standards, and the authentic Midwestern hospitality that defines life in Milwaukee.

David Kowalski, CEO & Founder

David Kowalski

CEO & Founder

David Kowalski grew up surrounded by Milwaukee's close-knit Polish community on the South Side, where his family operated a neighborhood plumbing supply store on Lincoln Avenue for over thirty years. After completing his business degree at UW-Milwaukee, he spent several years overseeing logistics for major gatherings at Henry Maier Festival Park, including the massive setup and breakdown cycles for Summerfest. Through that work, he recognized how few portable sanitation providers in the Milwaukee area truly delivered on their promises. In 2019, David founded Pinnacle Porta Potty Rental Milwaukee with one clear goal: bring dependable, high-quality service to every community from Walker's Point to West Allis. Outside of running the company, you'll find David cheering at American Family Field during Brewers season and pitching in with volunteer river cleanups along the Menomonee.

Sarah Chen, COO & Co-Founder

Sarah Chen

COO & Co-Founder

Sarah Chen relocated to Milwaukee after earning her MBA from Marquette University and immediately connected with the city's unique combination of lakefront beauty and Midwestern friendliness. Prior to co-founding Pinnacle Porta Potty Rental Milwaukee, she built more than ten years of operations management expertise with hospitality and catering firms that served events along Milwaukee's lakefront, inside the Wisconsin Center, and throughout the suburban communities. Sarah's thorough knowledge of Wisconsin's seasonal extremes — from bitter January gusts blowing off Lake Michigan to the sticky heat of summer festival weekends — keeps Pinnacle Porta Potty Rental Milwaukee's equipment and staff ready for every condition. She serves on the board of a Bay View neighborhood development group and spends her downtime kayaking along the Milwaukee River.
