OSI and the Community

Our owners Randy Conlon, Steve Gerstenberger, and Trent Pearson take pride in having lived in the Galesburg area all of their lives. In addition, our entire team is dedicated to supporting the communities we serve.

We are active members of several local and national organizations including:

Our History

Office Specialists Team HistoryIn November of 1989 two of three of OSI’s current owners — Randy Conlon and Steve Gerstenberger — established OSI. Both brought over industry experience having worked at other office products companies. The first month, they operated the business out of Steve’s first house – a small bungalow located in Galesburg. They had two employees in addition to themselves (all are still with the company today). At that time, OSI served the Galesburg community only, selling office supplies and furniture. OSI quickly grew with two additional employees and before Randy and Steve knew it, a 3,450 square foot commercial space located in Galesburg was the new home of their business.

In November of 1991 OSI became a member of National Office Buyers (NOB) currently known as Tri-Mega. Through this nationwide buying organization, we are able to purchase products direct from manufacturers at substantial cost savings. Doing so allows us to provide our customers with the opportunity to purchase products at equal or better prices than big box stores.

In October of 1992, we expanded with the purchase of Norris Office Equipment in Monmouth, Illinois. Following this purchase, we became the Authorized Sharp Copier dealer for a multi-county area. We then expanded again with the addition of a machine showroom in Galesburg located at 28 North Seminary Street – in August of 1993. The machine showroom expanded to a larger facility in February of 1996 and moved to 221 East Main Street. Having the bigger space allowed us to showcase and demonstrate our full line of Sharp multi-function products and facsimile machines.

OSI Continues to Grow

In November of 1999 OSI’s Machine Showroom/Service Center and Office Products and Furniture Divisions consolidated into a larger facility at 143 East Ferris Street in Galesburg. In August of 2000 the Computer Division was formed, also operating out of the Ferris Street location. Soon after, we merged with Missing Link Communications and this division grew to seven employees providing a full range of computer sales and service. The addition of a retail store in Kewanee, IL came in July 2001, which currently employs two product specialists. We expanded our Computer Division and in 2010 our third owner, Trent Pearson (who manages our Computer Division) became a partner of OSI along with Steve and Randy.

In March of 2011 we continued the expansion of our product offerings with the addition of janitorial, sanitation and restaurant supplies. This addition increased our ability to supply products to a diverse array of businesses, and facilities. After achieving strong growth in this new area of business, OSI joined NISSCO, one of the industries leading janitorial buying groups. This has allowed us an even greater product offering with the ability to compete against large distributors. Customers can now purchase these additional products at competitive pricing, along with their office supplies for delivery on our scheduled routes. This takes us one step further to being your single source provider.

Today, we are pleased to say we have 28 local employees who all take pride in serving the more than 900 customers within a 70-mile radius of Galesburg and Kewanee.

Through the years, as the locations of our business has changed and our product and service offerings have increased, a few things have never changed, and never will:

  • We are passionate about assisting our customers with service that exceeds their expectations.
  • Through our connections with manufacturers, we will continue to offer the best prices we can.
  • We provide our customers with productivity solutions, now and after their purchases.
