About Our Firm

Cole, Martin & Co., Ltd. (CMC) was established in August 1991 to provide accounting, computer consulting, and tax services to small and closely-held businesses. Stephen Cole, William Martin, and Janet Nelson are the owners. It has been located in the Northern Illinois region since its inception.


CMC prides itself on not being the traditional accounting firm focused solely on tax and accounting issues. Instead, CMC takes a proactive role in offering services and support to add value and grow businesses.

Each of our clients has unique business and tax needs. We look at each client and put them in the best position to succeed. Instead of an executive asking "Why isn't my CPA telling me this?", our clients find that we provide them with revealingly useful insights.

In the area of software implementation, CMC is especially proud of having team members with credentials in the areas of:

  • QuickBooks,
  • Peachtree,
  • Sage MAS90 and MAS200, and
  • Crystal Reports.

How often have you said “I wish my accounting firm understood my software”? We will make sure your financial results make sense. You can only make informed decisions to move your company forward with accurate, easy to understand financial data.

Client Service Approach

Our client service approach is simple. As a smaller firm, we can focus on active partner involvement and excellent client service, resulting in personal attention, accessibility, responsiveness, and dependability. We are accountants that will call you back. We know that all the expertise in the world is meaningless unless we take the time to work closely with you, listen to you, and understand your objectives.
