CPA & Founder

Dianne Carobus

CPA, Quickbooks & Financial Statements

As a CPA, Dianne has specialized in monthly accounting, financial statement preparation, compilations and reviews for Susan S. Lewis Ltd.'s clients. Working with the firm since December 2006, she loves helping small businesses and the interaction she has with business owners on a daily basis. Dianne also has extensive QuickBooks and other accounting software knowledge and has spent many hours assisting and training clients with their bookkeeping tasks. She has relocated to a warmer climate, and when not crunching numbers, loves to craft, travel, and play golf.

Julie Keating

Office Manager

Julie joined the Lewis team over 15 years ago. You'll likely talk to her several times as she's the friendly voice and face of the firm. She wears many hats, from scheduling appointments to client relations. When not multitasking in the office, she is multitasking at home. Julie enjoys cooking and entertaining and spending time with her family including her husband, three children and son-in-law, three grandchildren and one crazy French bulldog, Lola.

Patti Iwinski

Associate, Payroll Services

Patti brings years of accounting expertise and manages the weekly, biweekly and monthly payrolls for clients. She's also an active member of several not-for-profit organizations, including the St. Charles Moose Family Center, which provides support for children and seniors in need. She'll never pass up a raffle ticket for a good cause-which recently resulted in her winning a custom-made motorcycle.
