Technology on Purpose. A family-led MSP since 1991, now serving Southern Wisconsin, the Phoenix metro, and San Antonio-Austin.
Second generation. Same purpose.
Tim Radtke founded TSR Solutions in 1991 on a simple idea: technology should serve the business. That idea became our mantra: Technology on Purpose. Started with his brothers, Paul and Mike, alongside him, today the second generation is stepping in to leadership at TSR: Tommy Radtke as CEO and Johnny Radtke leading sales. We maintain the same commitment to plain talk, fast response, and long relationships, now across Southern Wisconsin, the Phoenix metro, and San Antonio-Austin.
We provide managed IT, co-managed IT, cybersecurity, cloud, and AI implementation among other offerings for small to mid market businesses. We work especially with Manufacturing, Healthcare, Legal, Professional Services, and Non-Profit. Work is coordinated from our Cedarburg headquarters, with coverage across teams in southern Wisconsin, Arizona, and Texas markets.
