Meet Our Sales Team

Shannon Sivak

Sales Manager

As the Global Sales Manager, I have been a valued Ikonix USA team member since 1999. I am responsible for the management, leadership, and development of sales personnel and sales channels for the Americas, Europe, Africa, and the Middle East. When I’m away from the office, I enjoy scuba diving, traveling, camping, and enjoying the outdoors.

Ryan Fink

Business Development Specialist

As an APT Business Development Specialist for the United States, I have been a valued team member since 2005. My extensive application and product knowledge enables me to be a valuable resource to my customers that extends well beyond the point of sale. I have developed employee training programs, assisted customers in navigating proper selections of equipment, and have extensive experience with technical support. I am fully dedicated to my customers. This dedication has resulted in the development of long-term relationships with customers such as BSH, Electrolux, Intertek, Frymaster and Hill Phoenix. I am a family man and sports enthusiast. In my spare time I enjoy bowling, golfing and traveling.

Ryan Fink


International Business Development Specialist

As the International Business Development Specialist at APT, I have truly enjoyed helping my manufacturing customer’s ship safe products throughout the world. I am proud to have received my B.S. degree in Marketing and Business Management from DePaul University. I am fluent in both Russian and Turkish. Outside of the office I love spending time with my family, taking long walks with my dog Lucy, and discovering new interests and cultures. One of my favorite quotes is by Francis of Assisi: “Start by doing what’s necessary, then do what’s possible; and suddenly you are doing the impossible.”


Eric Walusiak

Inside Sales Coordinator

I have been a proud team member of our Domestic Inside Sales team since the Fall of 2017. I graduated from Central Michigan University in the Spring of 2017 with my Bachelors in Business Administration with concentrations in Human Resources and Professional Sales. After happily living in Michigan for my four years of undergrad, I moved back to the Chicago suburbs. My passions and backgrounds for work include all sorts of customer experience roles. I apply this every day here at APT with the intentions of making positive impacts throughout all our customers and co-workers. Outside the office I try and pursue any and all outdoor activities, spending quality time with my friends and family, reading books and watching movies, and listening to live music.

Marie Lewis

Inside Sales Coordinator

As an Inside Sales Representative, I have been a proud member of Associated Power Technologies since the fall of 2017. I began my time at Associated Power Technologies with our Customer Care team, where I was able to get a firsthand look at how much we value our customer’s happiness. Ensuring our customers are completely satisfied from start to finish is my top goal. I attended the College of Lake County, where I received my degree in Business Administration with an emphasis in Marketing. When I am away from work, I enjoy hiking, traveling, and spending time with my family and friends.
