DEPARTMENT: Accounting

Toni Horsch, Manager

Toni has worked for Maner Costerisan for 25 years and brings nearly 30 years of experience to the firm. Prior to joining Maner, she served as an accountant for a national restaurant chain franchisee. She is now a manager and team leader in Maner’s Accounting and Outsourced Solutions department, providing expert outsourced accounting and payroll support to clients. Toni also specializes in offering payroll and accounting-related support to clients on Quickbooks, Sage 50, Business Central and Accounting CS.

Toni decided to enter the accounting industry because she always liked working with numbers and working on puzzles. She felt accounting was a natural fit for her. She enjoys providing solutions to a wide variety of clients and helping give them peace of mind wherever she is able. She has met so many interesting people. She stays in this industry and at Maner because of the opportunities available and the people. She loves being a part of such a talented team with leadership that enables her to grow and excel.

Toni grew up in Dewitt, Michigan. She now lives in East Lansing, Michigan, with her husband, Russell. She loves to cook, travel and sci-fi movies.

I believe if you stay positive, have a willing attitude, and keep smiling – this world is a much better place.
