Accounting Firms Insero and CDLM to Merge

Rochester, N.Y.-based Insero & Co. CPAs (Insero) and Ithaca, N.Y.-based Ciaschi Dietershagen Little Mickelson & Company LLP (CDLM) have signed an agreement to merge. The combined firm will have over 125 employees and will operate under the Insero & Co. name.

“The combination will expand the service offerings for our clients and the growth potential for our team members in each office location. The client base and team members experience for both firms complement each other so well and allow us to continue our growth strategy while maintaining our promise of the highest standard in everything we do,” says Nancy Catarisano, who will serve as MP.

“What excites me about this merger is that both firms provide a full range of accounting, auditing and tax consultation, planning and preparation services.” said John Dietershagen, who will serve as OMP for the Southern Tier locations. “However, with the merger, we can now expand Insero’s Outsource Accounting Services Group to Ithaca, Cortland and Watkins Glen, and build on CDLM’s government, education and nonprofit experience into the Rochester marketplace.”

The combined firm will provide attest, tax and consulting services, including outsourced staffing solutions, for middle market, small business and large multinational companies in the manufacturing, distribution, real estate, not-for-profit, education, government and employee benefit plan industries.
