John Cosich Founder and CEO READ BIO
John Cosich Founder and CEO

John Cosich is a founding member of Proven IT. Cosich is no rookie to the industry. He graduated from Valparaiso University in 1973 with a business degree, and landed his first job with Xerox Corporation in 1974. It was here where he gained significant industry experience and excelled as one of the top producers in the country.

After many years of toiling with the idea of starting his own company, Cosich opened Distinctive Business Products in 1982 with three employees, operating out of a garage. With a strong focus on sales and customer service, the company grew to over 130 employees with nine Chicagoland locations, topping the charts of Inc. 500 at #42 for America’s Fastest-Growing Private Companies within 10 short years.

In 1998, after 16 years, Global Imaging Systems bought Distinctive Business Products. John entered retirement, however his time off was short lived. With two sons having graduated from college, he thought it might be a perfect time start over again. In March 2003, Proven Business Systems was “born” with six employees and no customers.

In 2017, the company changed its name to Proven IT to reflect more than a decade of proven business solutions and success.

Shares life with individuals with intellectual and developmental disabilities with a full continuum of care. By serving society’s most vulnerable citizens, Misericordia also serves the families who want the best for them, yet cannot provide it at home.


A non-profit organization provides educational, vocational and residential services for children and adults with developmental disabilities.


The foundation provides quality-of-life grants through tax-deductible donations for Illinois families that care for children with developmental disabilities, especially Hydrocephalus. The grants provide stipends for families who don’t qualify for Charity Care, DSCC, Medicaid and other financial assistance programs. The stipends may be used for a wide variety of support and programs that assist their family member with special needs.

This Cameron Can Foundation is near and dear to our hearts as one of our employee’s sons is battling chronic, long-term hydrocephalus. The foundation originally directly supported his son, but due to his success, it has grown to support several children in the Chicagoland area.


Delivering on a PROMISE of excellence.
