I focus on delivering accurate and timely financial information to business leadership and all other stakeholders. I am always looking for better and more efficient ways to analyze and report on business information to help leaders direct business efforts where they are needed most.Main areas of business information I work with are sales and margin accounting, forecasting and budgeting, organizational level KPI's, purchasing information, and product costing.

I strive to provide the most critical and important information to decision makers. Sales trends, account membership, territory overviews, and financial data are examples of the kinds of information I deal with. Through developing knowledge and expertise, I have gotten more opportunities to work closely with management and affect important decisions. I continue to learn more about the health care industry and my business’s position in that industry.

Mar 2017 - Oct 2018

Operations Analyst

Mundelein, Illinois

I became an expert in my product division at our ERP system, operational processes, and financial accounting. This made me a key resource to management. I was often asked to create reports that did not exist at the time I was asked. However, I was able to use my knowledge of our systems to find the appropriate data in our databases. I also took on the extra responsibility of training other operations team members and product managers in the use of our ERP system and other processes. I controlled all costing information for products within my division. By using managerial accounting concepts, I helped realign our costs to better reflect actual costs. This immensely helped improve financial performance.

Jul 2014 - Mar 2017

Operations Specialist

This was my first role at Medline. I focused on my product division’s supply chain, systems, and financials. Through focusing on inventory management, I was able to help improve service levels while reducing surplus inventory. I spent a lot of time researching and changing our purchasing records to insure accuracy and proper sourcing. Finally, I had the opportunity to get more involved with our financials. After my first year, I had provided recommendations on changing costing rates which was approved and ultimately drove profits higher.

Jan 2013 - Jul 2014

Office Assistant

Vernon Hills, Il

I returned to Mangrove for a second summer before my senior year of college. Most of this summer was also focused on moving hard copy files into our electronic network. However, there was much more emphasis on indexing and filing these in a more organized way for easy access by other company personnel.

May 2012 - Aug 2012

Summer Office Assistant

Mangrove Cobrasource

Grayslake, Il

This was a summer job I had during college. I focused on scanning and entering paper documents into the company’s electronic network. I also worked on purging unneeded or duplicated files. This was all in preparation for the company’s move to another location.
